Auto Up Front Window

AUTO UP FRONT WINDOW

Anytime the batter 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.
