Power Window Inoperative - Passenger Door (Front)

POWER WINDOW INOPERATIVE - PASSENGER DOOR (FRONT)

DIAGNOSTIC FAULT INFORMATION




Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

CIRCUIT/SYSTEM DESCRIPTION
The driver and passenger door lock and side window switches are integrated control module switch assemblies. The Driver Door Switch controls the passenger window through a GMLAN message to the Passenger Door Switch (PDS). When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation.

CIRCUIT/SYSTEM TESTING

Passenger Power Window Inoperative From Driver Switch
1. Install a scan tool and display the Driver Door Switch Inputs data list.
2. Activate the passenger window switch in the up, down, and express down positions and verify that the Passenger LF Window Switch displays the correct parameter in relation to the actual switch position.
- If the switch parameter is incorrect, replace the DDS.
3. Display the Passenger Door Switch Inputs data list.
4. Activate the passenger window switch in the up, down, and express down positions and verify that the Passenger Window Switch displays the correct parameter in relation to the actual switch position.
- If the switch parameter is incorrect, replace the PDS.
5. Disconnect the power window motor connector and connect a test lamp between the control circuit terminals in the harness connector.
6. Verify that the test lamp illuminates when the switch is activated in both directions.
- If the test lamp does not illuminate, test the window motor control circuits for a open/high resistance. If the circuits test normal replace the PDS.
7. If the circuits test normal replace the passenger window motor.

REPAIR INSTRUCTIONS
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
- Front Side Door Window Regulator Motor Replacement
- Control Module References for DDS or PDS replacement, programming, and setup. Verification Tests Programming and Relearning
