2000 le sabre, power windows, door locks, side mirrors, not working all of a sudden


All - driver - passenger - front an back ? Look for broken wires inside the rubber boot from the body to the door ,driver side !

Power Windows Operation
Power Windows
The vehicle is equipped with power windows controlled by the door modules. The DDM receives a window switch request, over the SBI serial data, from either the passenger door module wired to the window switch pressed or from the driver door switch assembly. The DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation.
If the status information to permit window operation is correct, the DDM sends the command to the door module controlling the window to move the window as requested.
Windows Power and Ground
The windows are powered by discreet power and ground circuits. These circuits are in the same dedicated connector as the window motor drive circuits.

PWR/WDO 30 amp circuit breaker located in the rear fuse box ,DRVMDL fuse 10amp located in the same rear fuse box . This power the driver door module (computer )

The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door. The driver door module (DDM) is the master control for the door lock system but the rear integration module (RIM) contains the program that determines when the lock functions are permitted.
The exterior key cylinders are wired to either the DDM or the passenger door module (PDM), depending on the location of the key cylinder. The interior lock switches are wired to the driver door switch assembly (DDSA) and the PDM. The DDSA and the PDM send the lock switch requests to the DDM over the simple bus interface (SBI) serial data circuit. The DDM then sends the lock requests to the RIM over the Class 2 serial data circuits.
The door lock operation modes are controlled by the rear integration module (RIM). The RIM examines the requested function from the DDM, or the remote function actuator (RFA), as well as the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. The RIM determines if a locking function is permitted, and commands the DDM to perform the function permitted. The DDM then sends commands to the rest of the door modules via the SBI to implement the selected locking function.
All programmable modes of lock system operation are stored in the RIM. The RIM checks the lock function program selected against the lock requests, the transmission selection and ignition key switch condition to determine if the requested function is permitted. If the requested function is permitted, the RIM then commands the DDM to perform the lock function over the Class 2 serial data circuits. The DDM commands the individual door modules to perform the lock function over the SBI serial data circuit.


GOOD luck your going to need it !

B1751 Park/Neutral Switch Circuit Short to Battery DDM Go To Pinpoint Test K . B2425 Remote Keyless Entry Out of Synchronization DDM Go To Pinpoint Test L Need a professional grade scan tool to check fro these codes . Not a code reader for OBD2 codes .
  • The doors do not lock/unlock using the remote transmitter
  • Remote transmitter not programmed.
  • Remote transmitter.
  • DDM.
  • Go To Pinpoint Test F .

Did you program the new key fob ?

Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.
  1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.
  1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.
  1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.
  1. To exit program mode, turn the ignition to START or wait 7.5 seconds.
  1. NOTE: Failure to wait at least 20 seconds will cause programming failures. Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification

Changed bcm because auto door locks and driver window did not work, when i changed it everything work like it should but had to relearn key , when the key was relearned the locks and window stopped working...


Taking your vehicle to a qualified repair shop instead of mess with thing's you have no clue about ,is what you should have done . Replacing BCM'S - needs to be programmed .
If the body control module (BCM) is replaced, the following procedures must be performed in the following order:
BCM reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
Theft learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent. A new BCM will learn the Passlock™ information automatically but the powertrain control module (PCM) must still learn the theft information from the BCM.

Plus the bcm has nothing to do with the power window's DDM -the driver door module controls the window .
Programmable Automatic Door Locks
The automatic door lock feature can be programmed to control the door lock system. The automatic door lock feature is factory programmed to have all doors lock and unlock. For detailed instructions on programming the automatic door locks, refer to Vehicle Personalization in Personalization.
When the automatic door lock feature is programmed to control the door lock system, the driver door module (DDM), passenger door module (PDM) and body control module (BCM) will lock the vehicle doors if the following inputs are true:
• Ignition 1 input is active.
• All door jamb switch inputs are inactive.
• Cargo door or liftgate/liftglass ajar inputs are inactive.
• Transmission is shifted out of park.
This automatic door lock function will only occur once per ignition cycle unless, a door jamb switch input changes state to active and back to inactive. Then the DDM, PDM and BCM will lock all doors again.
Once the automatic door lock feature has locked the doors, the BCM will then unlock all the doors when the transmission is shifted into park.
Before replace these componets hooking up a factory scan tool an checking data input's an DTC'S - diagnostic trouble codes .

The driver door module (DDM) is connected on the standard corporate protocol (SCP) communication network. The DDM controls many functions including power windows, power door locks and remote keyless entry. The DDM also communicates with the driver seat module (DSM) to control the power mirror and seat memory functions.
Do you know anything about automotive electronic control modules ?
The driver door module (DDM) receives inputs from the digital transmission range (DTR) sensor, ignition switch, seat switch, window/door lock switches, lighting control module (LCM), keyless entry keypad switch and remote transmitter. The DDM outputs consists of keyless entry keypad switch illumination, power door lock actuators, luggage compartment release solenoid, horn relay, and lighting control module (LCM).

2003 gmc mirrors do not fold in


The power mirrors are controlled by a module (computer) DDM - drivers door module an the PDM - passenger door module .
Folding Mirror System
Folding Mirror System Controls
The folding mirror system requires signals from 2 separate switches. The mirror select switch must be in the neutral/fold position and the mirror direction switch must be activated to the left/extend or right/retract positions. Both switches are integrated into the DDM and provide direct signals.
Folding Mirror System Operation
Upon receipt of the required switch inputs the DDM will supply battery voltage and ground to the mirror fold motor control circuits to perform the requested extend or retract function. The DDM will also send a class 2 message to the PDM indicating the requested function. The PDM will supply battery voltage and ground to the mirror fold motor control circuits to perform the requested extend or retract function.

Power Mirror System
Power Mirror System Components
The power mirror system consists of the following components:
• The driver door module--Class 2 module with integrated switches and requires programming when replaced
• The passenger door module--Class 2 module with integrated switches, requires programming when replaced and also contains the RFA receiver
• The power mirror direction switch--Integrated into DDM and is a 4-position momentary switch that provides a signal input to the DDM for up, down, left/extend and right/retract with a mirror switch activation
• The mirror select switch--Integrated into DDM and is a 3-position switch that allows the operator to select the left or right mirror and also a neutral/fold position
• The left outside power mirror--Contains both the vertical and horizontal mirror motors and is serviced as a complete mirror assembly
• The right outside power mirror--Contains both the vertical and horizontal mirror motors and is serviced as a complete mirror assembly
• The body control module--Class 2 module that requires programming when replaced, serves as the power mode master and is the main message handler
• The DDM 10A fuse--Located in the I/P fuse block and is hot at all times
• The PDM 10A fuse--Located in the I/P fuse block and is hot at all times
• The memory switch, if equipped with memory mirrors--Supplied power by the DDM and provides a voltage signal to the DDM upon a switch activation
• The horizontal and vertical position sensors, if equipped with memory mirrors--Supplied a 5-volt and low reference by the DDM/PDM and provide a variable voltage signal to the DDM/PDM that is proportional to mirror position
• The park neutral position switch, if equipped with memory mirrors--Provides transmission gear selection information to the PCM and is used for memory recall and mirror tilt in reverse functions
• The powertrain control module, if equipped with memory mirrors--Class 2 module that requires programming when replaced and provides Class 2 message indicating transmission gear selection
• The driver information center (DIC), if equipped with memory mirrors--Part of the instrument cluster which is a Class 2 module that requires programming when replaced and is used to personalize the memory recall and mirror tilt in reverse functions
• Fold motor in each of the outside mirrors, if equipped with power fold mirrors--Provides extend and retract movements of the mirror and is serviced as a complete mirror assembly
Each of the outside power mirrors contains 2 reversible motors to provide horizontal and vertical movement of the mirror glass. The vertical motor operates the up and down directions and the horizontal motor operates the left and right directions. If equipped with power folding mirrors, each outside power mirror will contain a reversible fold motor to operate the extend and retract functions. Each of the mirror motors are circuit breaker protected.
DTC B1722
The driver door module (DDM) and passenger door module (PDM) switch the mirror fold motor control circuits to battery voltage and ground in response to mirror extend or retract command.

Need a factory scan tool to test !
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, observe the mirror horizontal and vertical position parameters in the Driver Door Module (DDM) and Passenger Door Module (PDM) data lists.
Operate both the left and right mirrors through the full range of movements.
Does the scan tool indicate that the left and right mirror horizontal and vertical position parameters are within the specified range?
0.50-4.75 V.
Your best bet , take it to a GMC , Chevy , buick or cadillac dealer
