Power Windows - Service Information

The power window system allows each of the door windows to be raised and lowered electrically by actuating a switch on the center console. A master switch on the front of the center console allows the driver to raise or lower each of the passenger door windows and to lock out the individual switches on the rear of the center console from operation. The power window system receives battery feed through a fuse in the Totally Integrated Power Module (TIPM), only when the ignition switch is in the RUN or ACCESSORY position.

The following wiring test determines whether or not voltage is continuous through the body harness to the front switch.

1. Remove the power window switch and bezel. See REMOVAL. 2. Disconnect wire connector from back of power window switch. 3. Switch ignition to the ON position.

4. Connect the clip end of a 12 volt test light to Pin 14 of the window switch harness connector. Touch the test light probe to Pin 10.  If the test light illuminates, the wiring circuit between the battery and switch is OK.

 If the lamp does not illuminate, first check fuse 13 in the Totally Integrated Power Module (TIPM). If fuse 13 is OK, then check for a broken wire.

Refer to the SYSTEM WIRING DIAGRAMS article.

NOTE: The power window motor test does not apply to models with the auto-express feature.

If the power window motor is receiving proper current and ground and does not operate, proceed with motor test. Refer to the SYSTEM WIRING DIAGRAMS article.

1. Remove front door trim panel as necessary to gain access to power window motor wire connector. Refer to REMOVAL . 2. Disconnect power window motor wire connector from door harness. 3. Using two jumper wires, connect one to a battery (+) source and the other to a good ground (-). 4. Connect the Negative (-) jumper probe to one of the motor connector terminals. 5. Momentarily touch the Positive (+) jumper probe to the other motor connector terminal.

When positive probe is connected the motor should rotate in one direction to either move window up or down. If window is all the way up or down the motor will grunt and the inner door panel will flex when actuated in that one direction.

6. Reverse jumper probes at the motor connector terminals and window should now move in opposite direction. If window does not move or grunt, replace the motor.

If window moved completely up or down, reverse the jumper probes and cycle window to the opposite position to verify full operation.

If motor grunts and does not move, verify that regulator is not binding.

Anytime the battery is disconnected or in a run down/low voltage state, the auto-up (express) windows must be calibrated.

To calibrate the auto-express feature, perform the following:

1. Turn the Ignition to the Run position.

2. Using the scan tool, perform an ECU reset. 3. Position the window at the midpoint of travel. 4. Move the driver side front window upward until the window stalls in the full up position. Allow the window motor to stall for at least 2 seconds before releasing the switch. 5. Move the driver side front window downward until the window stalls in the full down position. Allow the window motor to stall for at least 2 second before releasing the switch. 6. Repeat steps 3, 4 and 5 for the passenger side front window. 7. Verify the windows are properly calibrated by operating the express down and up features. Repeat this procedure if the calibration failed. If unable to properly calibrate after the second attempt, check the Driver's Door Module (DDM) and Passenger's Door Module (PDM) for Diagnostic Trouble Codes (DTCs) and correct as required.
