SAAB front passenger seat position sensor

Are the connectors actually wired the same? Check the wiring diagrams for each seat if you can find them, otherwise trace the wiring from the internal components in the seat to the connector and make sure the heaters are going to heater power pins in the original harness, and temperature sensors are going to temperature sensor pins (temperature sensors may be polarized, that is, it makes a difference which pin goes to positive and which to ground).

This is usually under the driver's seat or the front passenger seat.

Heated Seats
This system allows independent seat electrical heating of each front seat on demand.
The components of the system are:

• the seat heater mats located on the seat cushion and backrest.
• the heated seat module located on the passenger power seat track and cushion frame on manual seat track.
• the heated seat switches, located on the electronic automatic temperature control (EATC) module.
• temperature sensors, located in the seat cushion heater mats.

A new heater mat will come assembled on a new foam pad.
Climate Controlled Seats
The climate control seat system is able to heat and cool the front seats. Each climate controlled seat is operated by push-buttons on the electronic automatic temperature control (EATC) module located on the instrument panel. Each front seat temperature is then monitored and controlled by the climate control seat module (CCSM) located on the front passenger seat track.
The climate controlled seat system contains the following components:

• EATC module
• CCSM
• Thermo-electric device (TED) and blower assembly within each front seat cushion and backrest
• Air filter (attached to each TED and blower assembly)
• Cushion TED adapter attached to the cushion frame
• Cushion and backrest manifolds
• Cushion and backrest foam pads
• Cushion and backrest trim covers
• Seats
  Front Seats
  NOTE: The high speed controller area network (HS-CAN) circuits that pass through the passenger seat harness are part of the main HS-CAN LOOP. If the front passenger seat-to-floor connectors are disconnected, a NO START condition will result.
  NOTE: The medium speed controller area network (MS-CAN) circuits that pass through the driver seat harness are part of the main MS-CAN LOOP. If the front driver seat-to-floor connectors are disconnected, various MS-CAN modules will not be able to communicate.
  The front seats can be equipped with the following systems:
  
  • Two-way manual seat track (passenger only)
  • Four-way manual seat track (driver only)
  • Six-way power seat track
  • Manual recline
  • Power recline
  • Backrest, without fold flat
  • Backrest with fold flat (optional, passenger only)
  • Heated seats
  • Heated/cooled climate controlled seats
  • Memory driver seat
  • Manual lumbar (driver only)
  • Power lumbar
  • Adjustable head restraints
  • Seat side air bags (standard)
  • Occupant classification sensor (OCS) system on passenger seat
  
  Driver Seat Module - Memory Seat
  The power driver seat, power outside rear view mirrors and power adjustable pedals are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option. The DSM is located on the driver seat track.
  This system allows automatic positioning of the driver seat to 2 programmable positions.
  
  • A power driver seat position can be stored at any time. The driver must move the seat to the desired position using the driver seat switch assembly. The driver must then depress the memory SET switch which activates the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out), the driver must select a memory position. Memory 1 is selected by depressing memory switch 1. Memory 2 is selected by depressing memory switch 2.
  • If no memory switch input is received within the 5-second time limit, the operation is aborted and the memory seat position switch (set switch) LED is turned OFF. This also occurs if one of the following inputs is received during the 5-second programming limit:
    • Driver seat control switch
    • Memory seat position switch (set switch)
    • Power adjustable pedal switch
  A programmed seat position can only be recalled when the transmission selector is in PARK or NEUTRAL with the ignition switch in the RUN position. A position may be programmed at any time.
• Principles of Operation
  Driver and Passenger Power Seats Without Memory
  The driver and front passenger power seat motors are hardwired to the seat control switches on each respective seat. The circuits are normally at ground through the seat control switch. Each individual seat track, recliner (if equipped) and lumbar (if equipped) motor circuit is switched to power when the specific adjustment position is selected.
  
  Power Driver Seat With Memory
  The driver power seat is controlled by the driver seat module (DSM), if equipped. The memory driver seat feature allows the driver to program a personalized seat position that can be recalled using the memory switch or a remote keyless entry (RKE) transmitter. There are 2 memory settings possible. The outside rear view mirror positions are also stored and recalled with the power driver seat positions.
  The DSM is located underneath the driver seat cushion frame. The DSM does not require calibration to the driver seat track.
  The driver seat control switch provides voltage to the DSM when activated. The NEUTRAL position of each driver seat control switch position is a ground state through the seat control switch contacts. A voltage input causes the DSM to power the appropriate motor until the input is removed. Ground is the normal state of the motor circuits through the DSM and is not switched to control the motors. The DSM internally switches the appropriate circuit from ground to power for operating the motors.
  As the seat is adjusted, the DSM constantly monitors the motor position sensors to record the current seat position. The DSM will remove power from the motor upon termination of the seat control switch input or if the DSM does not see movement from the motor by monitoring the position sensor.
  The DSM communicates diagnostic trouble code (DTC) and other information using the MS-CAN communication bus. It should be noted for diagnostics that because CAN bus communication is more robust and reliable than other methods, it may be possible to have limited module communication with one of the CAN bus circuits disconnected or shorted to ground. Refer to Section 418-00 for information concerning MS-CAN bus communication.

Do you have memory or not ?

Taking the vehicle to a qualified repair shop an having a diagnostic scan of the seat module's done could save time an money , by not replacing parts needlessly .

DTC B0058 Right Front/Passenger Pretensioner Deployment Loop Open.
The passenger seat belt pretensioner deployment loop consists of a seat belt pretensioner-RF and the seat belt pretensioner-RF high and low circuits. A shorting bar used within the seat belt pretensioner connector shorts together both the seat belt pretensioner high and low circuits when the connector is disconnected. This will help to prevent unwanted deployment of the pretensioner during servicing. During a frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the seat belt pretensioner. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a diagnostic trouble code (DTC) will be stored in memory.
DTC B0084 Left Front/Driver Seat Position Sensor Circuit
The inflatable restraint seat position sensor (SPS) is used to determine the proximity of a front driver or passenger seat position with respect to the frontal air bag. The SPS interfaces with the sensing and diagnostic module (SDM). The state of the SPS allows the SDM to disable stage 2 of the frontal air bag for a front seat that is forward of a forward/rearward point in seat track travel. The SPS is a hall effect sensor that is mounted on the inside seat track of both the driver and passenger seats. The seat track includes a metal bracket that shunts the SPS magnetic circuit creating 2 states of seat position. The shunted state represents a rearward seat position. The non-shunted state represents a forward position. The SPS provides 2 current ranges, one range for the shunted state and a second range for a non-shunted state. These 2 states are inputs to the SDM. State 1 (shunted) being the rearward threshold and state 2 (non-shunted) being the forward threshold. When the SDM receives input from a SPS that state 1 threshold is reached (seat is rearward) the SDM will not disable stage 2 deployment, if required by the deployment sensors. When state 2 threshold is reached (seat is forward) the SDM will disable stage 2 deployment on the side the seat is forward. The SDM monitors the SPS circuit and if a fault is detected the SDM will set codes B0083 or B0084 and defaults to disabling stage 2 frontal deployment. This will only default on the side of the vehicle the sensor has a fault. Its important to understand that the SPS is secondary to the passenger presence system (PPS) and the manual instrument panel (I/P) module disable switch. If either one of these devices are in the disable mode the passenger air bag will not deploy regardless of the SPS status.
You should take this to a qualified repair Shop ! Takes special tools to test .

There is no relay for the passenger side air bag . What seams to be the trouble ? There is possibly a code set in the air bag control module .
Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) The air bag supplemental restraint system (SRS) is designed to provide increased collision protection for front seat and second row outboard occupants, in addition to that provided by the 3-point safety belt system. Safety belt use is necessary to obtain the best occupant protection and to receive the full advantage of the SRS.
This vehicle line contains dual stage deployment (advanced restraint system) driver and front passenger air bag modules. These vehicles are also equipped with driver and front passenger safety belt retractor pretensioners. These vehicles can also be equipped with optional side air curtains that deploy from the A-pillar to the C-pillar upon a side impact. Vehicles with optional side air curtains are also equipped with seat side air bag modules in the front seats.
Side air curtains deploy from the headliner, protecting the first and second row outboard occupants during a side impact. Seat side air bag modules deploy from the outboard front seat backrest upon a side impact. In addition, a front impact severity sensor is mounted to the lower radiator support, a seat position sensor is mounted to the driver seat and a usage detection switch is added to the front driver and passenger outboard buckles. If equipped with optional side air curtain modules and seat side air bag modules, there are an additional 4 side impact sensors.
Vehicles are also equipped with an occupant classification sensor (OCS) system as part of the front passenger seat. The OCS system includes 2 OCS rails and an OCS module.
Passenger Air Bag Deactivation (PAD) Indicator
The passenger air bag deactivation (PAD) indicator is a visual indicator used to inform the front seat occupants of the passenger air bag deactivation state. The PAD indicator is a stand-alone lamp installed into the vehicle instrument panel in a position visible to each front seat occupant.
The restraints control module (RCM) controls the state of the PAD indicator through a direct hardwire connection, based on information provided by the occupant classification sensor (OCS) system. The PAD indicator is lit to indicate the passenger air bag module is disabled. An exemption to this is when the front passenger seat is determined to be empty and passenger safety belt buckle unbuckled, and therefore indication of a deactivated passenger air bag module is not necessary. In all other cases, the PAD indicator is unlit when the passenger air bag module is enabled.
When the ignition switch is in the ON position, the PAD indicator prove-out period is initiated by the RCM. The RCM briefly activates the PAD indicator to prove-out the indicator function and verify to the front occupants correct functional operation of the PAD indicator.
The PAD indicator will be lit/unlit within 1.0 to 1.5 seconds of a change of state from the OCS system.
When an OCS system fault is present, the RCM defaults the passenger air bag module to the last valid state received from the OCS system until the ignition switch is turned OFF. If the OCS system fault is still present when the ignition switch is turned ON, the RCM defaults the passenger air bag module to enabled regardless of the size of occupant in the front passenger seat. The PAD indicator will be unlit. For information on the OCS system, refer to Occupant Classification Sensor System in this section.
The following table indicates the passenger air bag status and the PAD indicator status based the size of the front outboard passenger occupant.

The dirver seat module is attached to the underside of the seat frame. It must be calibrated if replaced. The dealer can use a tool to get failure codes (DTCs) from teh module. 1/2 hour labor charge to extract codes.


Front Seats
The front seats have the following features:

• Driver memory
• Power lumbar (optional)
• Manual lumbar
• Horizontal, vertical front and rear tilt adjustments (driver)
• Horizontal, vertical front tilt adjustment (passenger)
• Power recline
• Climate controlled (optional)

Adjustment of the seat may be accomplished with the seat control switch located on the side of the seat.

Principles of Operation
Driver Power Seat - Memory
NOTE: The memory power seat track may stall when operating at 0°C (32°F) or below. Once the vehicle's interior temperature rises above 0°C (32°F), normal operation should return.
The driver power seat is controlled by the driver seat module (DSM). The DSM does not need to be configured, however the driver seat does need to be calibrated when the DSM is installed. The driver seat control switch provides voltage to the DSM when activated. The NEUTRAL position of each driver seat control switch position is a ground state through the seat control switch contacts. A voltage input causes the DSM to power the appropriate motor until the input is removed. Ground is the normal state of the motor circuits through the DSM and is not switched to control the motors. The DSM internally switches the appropriate line from ground to power to adjust the motors.
As the seat is adjusted, the DSM constantly monitors the motor position sensors to record the current seat position. The DSM will remove power from the motor upon termination of the seat control switch input or if the DSM does not see movement from the motor by monitoring the position sensor. The DSM must be calibrated to the seat track it is controlling. For additional information, refer to Seat Calibration. Once the DSM is calibrated to the seat track, it will only allow movement within the calibrated range.
Seat Calibration
The DSM is calibrated using a diagnostic tool. The calibration procedure automatically powers the driver power seat through its full range of motion and records the FULL STOP positions by monitoring the motor position sensors. Once the FULL STOP positions or range of the seat have been recorded, the DSM will only operate within the calibrated range. Any input attempting to drive the seat beyond the calibrated range will be ignored. This calibration is used for all seat control functions including manual switch control and memory recall positioning. During the seat calibration, the DSM may identify a function that is inoperative, such as a position sensor not changing. If the DSM identifies a concern that has a related diagnostic trouble code (DTC), the DSM will set the related DTC at the end of the validation procedure.
The calibration procedure powers the seat track adjustments to the end of their travel, which is determined by the DSM sensing a change of state in the motor position sensors. If there is a concern with the seat track or motor position sensor that limits the travel, the DSM will interpret the stopping point as the end of travel and store the position. The DSM is not able to determine if the seat has moved to its FULL TRAVEL position. It is only capable of monitoring and storing the amount of travel seen by the position sensor changing states.
For additional information on carrying out the power seat calibration procedure, refer to the diagnostic tool operating manual.
Memory Seat
Memory seat positioning can be recalled with the memory switches on the driver door panel or a programmed remote keyless entry transmitter. In either case, the DSM receives a memory recall 1 or 2 command from the driver door module (DDM) over the SCP communication network. The memory recall switches are a hardwired input to the DDM. The DDM also receives the remote keyless entry transmitter signals. Once a valid memory recall command is received from the DDM, the DSM moves the driver seat to the position stored in memory by powering the appropriate motors and monitoring the motor position sensors until the position is reached.
This system allows automatic positioning of the driver seat to 2 programmable positions.

• To program position 1, move the driver seat to the desired position using the seat control switch. Depress the set button. Within 5 seconds, depress button 1.
• To program position 2, repeat the previous procedure using the set button and button 2.
• To recall position 1, depress button 1. To recall position 2, depress button 2.

A position can only be recalled when the transmission selector is in PARK or NEUTRAL. A position may be programmed at any time.
Easy Exit/Easy Entry
The easy exit function moves the seat backwards about 2 inches when the ignition key is removed from the ignition switch. The DSM receives a key out command over the SCP communication network and powers the driver seat rearward. This function will not operate if the seat is less than the travel distance to the end of the track, or the function has been deactivated at the message center driver personality settings. The DSM will also cancel this operation if a valid input command is received, such as the seat control switch or memory recall request.
The DSM will record the current seat position before powering the seat for an easy exit function. This recorded position will be used to return the seat to this position on the easy entry operation. During easy entry operation, the seat is returned to the position previous to the easy exit operation. Easy entry operation will be cancelled if a valid input command is received by the DSM.
Passenger Power Seat
The passenger power seat motors are hardwired to the passenger seat control switch. The circuits are normally at ground through the seat control switch. The individual circuit is switched to power when the specific adjustment position is selected.

Search Saab forums for your year and model to get advice on the driver's window. Re the heated seats not turning off -- try spraying some WD40 into the switch and turning on/off several times to clean it. If that doesn't work, you'll need to take out the switch and either repair or replace it.

try the big fuses under the bonnet near the battery and the wiring connections to these fuses

Get your Heater Core Checked...that is a sure indication.
