Power Window Motor: Testing and Inspection

Window Motor Initialization

NOTE: Initialization is required to learn both the full UP and full DOWN positions of the glass as it travels through the glass channel. Once initialized, obstacle detection is enabled.

NOTE: 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.
- grease or lubricants are applied to the window regulator or glass run.

NOTE: Install and tighten all window components to specification before carrying out the initialization procedure.

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

De-Initialization procedure

1. Turn the ignition key ON.

2. Operate the window control switch in one-touch up mode and remove power from the window motor while the window is moving by one of the following methods:

1. Disconnect the vehicle battery cable while the window is moving.

2. Disconnect the window motor connector while the window is moving.

3. Remove the LH or RH front window motor fuse while the window is moving.

3. This will de-initialize the window motor and reset the window motor to its original factory settings.

4. Reconnect the battery cable, window motor connector or window motor fuse before proceeding to the initialization procedure.

Initialization procedure

WARNING: Keep objects and body parts clear of the glass panel when carrying out the initialization procedure. During the initialization procedure, the glass panel closes with high force and cannot detect objects in its path. Failure to follow this instruction may result in serious personal injury.

NOTE: The front window must be in the full OPEN position for this procedure to operate correctly.

NOTE: If the initialization procedure is only partially completed, the front window motor will remain de-initialized and will not operate in one-touch up mode.

5. Turn the ignition key ON.

6. Press and hold the window control switch until the window glass stalls for 2 seconds into the glass top run and release the switch.

7. Pull and hold the window control switch until the window glass stalls for 2 seconds at the bottom of its travel and release the switch.

8. Test for correct window operation by carrying out the one-touch up feature. If the window does not operate correctly, carefully repeat this procedure.
