Rear Window Motor Initialization

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

NOTE: The rear window motor is in error mode when shipped and will be inoperative until initialized.

NOTE: This procedure must be carried out when repairs are performed on any part of the power rear window system including when: the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window glass module is installed, and any operation in which grease or lubricants are applied to the power rear window system.

NOTE: All power rear window components (window glass module, window regulator, window motor, and glass runs) must be installed and torqued to specification before carrying out this procedure.

NOTE: Once the ignition key is turned to the ON position in Step 6, it must remain on until the entire procedure is completed.

NOTE: Step 7 requires that the power rear window control switch be held in the CLOSE position (fully clockwise) until the power rear window motor stalls the window into the upper header seal. Step 8 requires that the window control switch be momentarily turned to the OPEN position.

NOTE: Step 9 requires that the power rear window control switch be held in the CLOSE position (fully clockwise) until the window stalls into the upper header seal and the window carries out its down-up sequence, indicating successful completion of initialization.

NOTE: The key-in-ignition chime can cause the vent button to be pressed more or less than six times due to the distraction of the chime.

NOTE: Steps 1-6 must be completed within 30 seconds. The entire procedure must be completed within five minutes.
