Sounds like you have trapped/chaffed wiring under seat or around seat recline hinge, remove seat and have a close look at the wiring. disconnect battery first because airbags in seat and seat belt pretensioners i think are fitted to this car. good look

Hi, 1997 Jaguar xk8 convertible. Drivers seat electrics not functioning where is the relevant fuse?


Unfortunately for many of the Jaguar models there is only one fuse for all the functions of each seat. The fuse locations can be found in the electrical section of the owners manual or Roadside emergency service section of the Vehicle Care Manual. In a 2000 XK8 the fuse for the drivers seat is fuse #1 (20A) located in the drivers side fascia fusebox (at left end of instrument panel). Not sure if it was changed from 1997 but doubt it.

Had problem of seat fuse blowing on XJ8 every time the headrest adjustment was attempted (shorted motor). Very tiring to deal with but be aware if fuse continues to blow you might have a motor or wiring problem. Good luck.

I just purchased a 2005 cadilllac srx v8 n i cannot get the third row seat tto function? Help?


Rear Seat Switches
There are three push button switches that are used to operate the power folding seat; front stow switch, rear stow switch, and recline switch. The front stow switch is located in the right rear quarter trim panel just behind the second row seat. The rear stow and recline switches are located in the right rear trim panel just inside the liftgate. Battery positive voltage is supplied at all times to all three switches from the FFS SW Fuse located in the left rear fuse block. The folding seat will operate only in a supervised mode, i.e. press and hold the selected switch button through the entire cycle of operation, or release the switch when the desired seat position is reached. When any folding seat switch is pressed, it sends a 12 volt signal through the switch signal circuit to the RSM. The RSM then commands the appropriate seat motors to move in response to the switch signal.
Rear Seat Module and Power and Ground
The rear seat module controls the position of the third row seat. When commanded it moves the seat from the seated position to the stowed position, or, from the stowed position to the seated position. With the seat in the seated position, the RSM can also move the angle of the seat back forward or rearward.
Battery positive voltage is supplied at all times to the module through the battery positive voltage circuit and the FFSM fuse located in the left rear fuse block. This voltage is used to power up the RSM and also to apply power to the seat motors when commanded. The RSM is grounded through the module ground circuit and G401.
The first place to start would be check the fuse's .Do you know where the left rear fuse block is located ? Fuse Block - Left Rear
In the passenger compartment, near the left side of the rear seat under the carpet
If the fuse is good next thing to do would be ,have check for DTC'S in the rear seat module ! This has nothing to do with check engine light or OBD 2 diagnostic trouble codes an a code reader for said OBD2 codes will not work . Would need a factory scan tool to check these codes.
DTC B1395
Battery positive voltage is supplied at all times to the rear seat load floor switch and the rear seat position switch by the rear seat module (RSM). The RSM monitors these battery positive voltage supply circuits for the protection of internal circuitry of the module.
DTC B1395 Device Voltage Reference Output 1 Circuit
DTC B1420 Device Voltage
Battery positive voltage is supplied at all times to the seat adjuster switch and the memory seat module (MSM) through the same circuit. The MSM uses this battery voltage input to determine if battery positive voltage is applied to the seat adjuster switch.

2004 Chevrolet Avalanche driver side heated seat switch with pedal adjustment and memory does nothing, doesn't light up or anything. The passenger side heated seats work perfect. Does this sound like


The left I/P fuse block also contains the 25A LT DOORS CIRCUIT BREAKER which could be defective (no 12V on ORG lead). The I/P relay block contains the 30A SEATS CIRCUIT BREAKER which, if defective, would affect the memory seat module (also no 12V on ORG lead). The pedal adjust circuit receives power through the 15A EAP FUSE in the underhood fuse block.

Car only blows heat on passenger side, Drivers side still cold even after replacing the actuator. What else could it be?


If the blower motor is running, that means the 30A HVAC BLOWER fuse is OK. The HVAC control module obtains power through the 10A DIC/RKE fuse in the right instrument panel junction block and the 10A A/C CRUISE fuse in the left instrument panel junction block. Output from the HVAC control module controls the mode actuator and the recirculation actuator. You replaced one of the two. The other one may be defective or the replacement one may be defective. Also, the HVAC control module may be defective and not producing door control output

GMC Yukon Seat Switch


You don't mention what year your Yukon is ? This could very well be a control Module problem .
I'll post how the power memory seat's work or are suppose to work !

Memory Seats Description and Operation

Battery voltage is supplied to the memory seat module through a 25 A circuit breaker. The memory seat module supplies the seat adjuster switch assembly with a battery positive reference voltage. While the seat adjuster switches are in an inactive state the switch contacts are closed to the adjuster switch common circuit. When a seat adjuster switch is pressed to an active state the switch contact is closed to the reference voltage circuit. Battery voltage on a switch signal circuit indicates to the memory seat module the switch status is active. Each seat adjuster motor is controlled by the memory seat module through 2 motor control circuits. While the seat adjuster motors are in an inactive state the motor control circuits are closed to ground circuit contacts within the memory seat module. The memory seat module operates the seat adjuster motors by switching one of a motors control circuits to battery voltage. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.


Memory Set/Recall Operation
The seat adjuster motors are equipped with internal position sensors. The adjuster motor position sensors are monitored by the memory seat module and are used to determine the seat position when storing or recalling memory settings. The driver seat adjuster motors use potentiometer type position sensors. The position sensors are supplied with a 5 V reference and ground circuits from the memory seat module. The position sensor signal circuits return to an analog input within the memory seat module. During adjuster motor operation the position sensor provides a voltage change proportional to the change in revolution of the adjuster motor shaft. The memory seat module monitors the voltage from the position sensor signal circuits to determine the adjuster motor positions when storing or recalling memory seat position settings.
The memory recall switch assembly on the driver door provides inputs to the driver door lock/window switch. Battery voltage is supplied to the memory recall switch assembly from the driver door lock/window switch. When a RCL 1, RCL 2, or EXIT switch is pressed, the switch contacts close the appropriate switch signal circuit to the battery voltage supply circuit within the memory recall switch assembly. When the driver door lock/window switch receives active switch signals from the memory recall switch assembly, the appropriate commands are sent to the memory seat module using the GMLAN Serial Data circuit. The Body Control Module software version determines the personalization features available.
Memory seat recall operation is allowed only with the transmission selector lever in the PARK position while the ignition is on. The transmission selector lever position data is provided to the memory seat module by a message through the GMLAN Serial Data circuit.

There are somethings listed you are not familiar with , like GMLAN Serial Data circuit ,maybe Body Control Module software etc... GMLAN is a communincation network that the computers on the vehicle uses to share information , transmit commons etc... you can google it to read about it .

There are DTC'S - diagnostic trouble codes that can set in the module in control . Do you know what DTC'S are .

5) Memory Seat Module is under the front of the driver seat , you could look under an see if all the connectors are fully seated.

The best diagnostic step would be to hook up the factory scan tool an see what the computer is seeing as far as inputs from the switch an outputs it's sending . I wouldn't suggest you take the seat apart an try testing electrical inputs etc.... unless you very familiar with automotive electrical systems an circuits .
