Window Motor Initialization: Notes

NOTE: Initialization is required to learn both the full up and full down positions and the profile of the glass as it travels though the glass channel. Once initialized, obstacle detection is enabled.

NOTE: For Zephyr only, the front window motor must be de-initialized, then initialized whenever the front window motor is removed from the window regulator drum housing, a new window regulator is installed, a new window glass is installed, a new top run is installed or for any operation in which grease or lubricants are applied to the window regulator or glass run.

NOTE: A new (original factory setting) or de-initialized LH or RH front window motor will not operate in one-touch up or one-touch down mode until initialized. If a new LH or RH front window motor has been installed, proceed to the initialization procedure.

NOTE: If diagnosing a LH or RH front window switch problem, perform the window initialization procedure before replacing the window switch.

NOTE: All LH or RH front window components (window glass, window regulator, window motor, seals and glass top run) must be installed and tightened to specification before carrying out the initialization procedure.

NOTE: Excessive bounce-back (window reverses direction with no obstructions present) may indicate that a de-initialization procedure may need to be performed.
