Window Motor Relearn Procedure

A relearn procedure may need to be performed after the following repair procedures have been completed:

When the window glass had to be realigned
When the window glass has been replaced
When the door has been replaced and the original window motor has been reused
When the window regulator has been replaced and the original window motor has been reused

The technician may experience the following symptoms when performing the express up function:

The glass may stop before reaching the top of the window frame
The window may auto-reverse when reaching the top of the window frame

This is caused by the window motor still retaining the original travel settings prior to being reinstalled with the new components

NOTE:

Prior to performing the relearn procedure the vehicle must have all 4 wheels properly inflated and mounted, the vehicle must be sitting on a level surface and all doors must be completely closed.

To relearn the window motor, follow these steps:

Ignition ON.
With a scan tool, select Module Diagnosis, K9 Body Control Module, Configuration/Reset Functions and then select the appropriate Clear Window Learn Values for the window motor requiring the relearn procedure.

NOTE:

For vehicles equipped with a folding convertible top, if either a front or rear window must be relearned, both window motors on that side of the vehicle must have the learn values cleared.

After the Clear Window Learn Values procedure, exit the scan tool learn procedure completely, the power window cannot be normalized and will not function until you exit the program.
Perform the appropriate Window Motor Normalization Procedure listed above.

The window motor has now been calibrated to the new travel settings and will function normally.
