Info - Power Window Regulator Now Available Separately From Motor

This bulletin is being revised to add the service procedure. Please discard Corporate Bulletin Number 05-08-64-029A (Section 08 -- Body and Accessories).

This bulletin is being issued to inform technicians that when performing a repair to the power window system, it is no longer necessary to replace the complete window regulator assembly. GMSPO has released the power window regulator for the left and right front doors separately from the motor.

Removal Procedure

1. Raise the window.

If the window motor is inoperable, remove the window to gain access to the window motor retaining screws. Refer to Window Replacement - Front Door.

2. Remove the power window module. Refer to Module Replacement - Front Power Window.



3. With the window regulator on the bench, remove fasteners one (1) and two (2) which will disconnect the drive housing and motor (4) from the rail (5).

Important: Do not allow cable gear/spool to come out of the housing. As the motor slides out of the gear/spool, hold the gear/spool into the housing with your fingers. The spool will unwind if it comes out of the housing.

4. Holding the motor and housing together, remove fastener three (3).



5. Slide the motor partially out of the gear/spool allowing finger access to the gear spool (6). Hold the gear/spool into the housing and remove the motor (7).

Installation Procedure

1. Install motor by aligning gear teeth and mounting points simultaneously, pushing the motor into the gear/spool and installing the motor to housing fastener first (3).
2. Slide the motor and housing assembly (4) onto the rail (5) and install the fastener number two (2).

Notice: Refer to Fastener Notice.
