Power Window Motor: Testing and Inspection

WINDOW MOTOR INITIALIZATION

CAUTION: Make sure that no obstructions are present in the window system when carrying out this procedure.

NOTE:
- The LF/RF window motor is in proportional up/down mode until initialized.
- The LF/RF window motor must be reinitialized whenever: the motor is removed from window regulator drum housing, a new motor is installed, a new window regulator is installed, new window glass is installed, glass top run removal or installation or when carrying out any operation in which grease or lubricants are applied to the window system. Refer to the De-Initialization Procedure prior to performing this procedure (unless a new motor is being installed).
- All LF/RF window components (window glass, window regulator, window motor and glass top run) must be installed and tightened to specification before carrying out this procedure.
- If this procedure is only partially completed, the LF/RF window motor will remain un-initialized and only the proportional up/down functions will operate.

1. Start with the ignition key in the OFF position and with the LF/RF door open.
2. Turn the ignition key to the ON position.
3. Activate and hold the window control switch in the DOWN position until the window glass stalls for one second at the bottom of its travel and release the switch.
4. Activate and hold the window control switch in the UP position until the window glass stalls for one second into the glass top run and release the switch.
5. Verify correct operation of the LF/RF window by carrying out a one-touch down, one-touch up, proportional down and proportional up. If the window does not operate correctly, carefully repeat this procedure.

De-Initialization Procedure

NOTE: A motor which is initialized already (one-touch up and one-touch down are functional) must be de-initialized prior to carrying out the window motor initialization procedure.

1. Start with the ignition key in the RUN position and the LF/RF door open.

2. NOTE: Steps 2 and 3 must be performed within 8 seconds.

Turn the ignition key from OFF to RUN 5 times.

3. Press the window control switch to the one-touch DOWN position second detent) and release.
4. Verify that the window only performs proportional up and down movements. If the window still performs auto operations, carefully repeat this procedure.
