Replacing The Power Window Motor & Regulator On A '99 Silverad

[GMcarnut]

Hello ladies and gents,

 

I found a solid write-up on replacing the power window motor & regulator on a '99 Silverado. Here's the walk-through

 

 

1) Raise the window. If the window motor is inoperable, remove the window to gain access to the window motor retaining screws.

 

2) Remove the power window module.

 

3) Remove the trim panel.

 

4) Remove the water deflector.

 

5) Disconnect the wiring harness from the window motor assembly.

 

6) Remove the 2 bolts holding the window to the regulator.

7) Remove the bolts from the window regulator.

 

**The window regulator bolts are shown here**

 

8) Remove the window regulator assembly from the door folding both sides together.

 

9) Remove the window regulator motor.

 

10) 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).

 

**Shown here: Fasteners one (1) and two (2) which will disconnect the drive housing and motor (4) from the rail (5)**

 

 

Caution: 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.

 

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

 

12) 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).

 

 

To install:

 

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).

 

3) Rotate the motor and housing assembly to align the attachment point for attachment number one (1) and install the fastener. Tighten the bolts to 44 inch lbs. (5 Nm).

 

4) Install the power window module.

 

5) Install the window if removed.

Can you get just a replacement motor? Are there any other GM models that have the same exact motor? I have a window regulator assy with a bad motor that I'd like to replace just the motor. Thanks for the excellent write up.

moving this back up....and still looking for a replacement motor. Is there any other GM vehicle that uses the same motor...or do all/most GM vehicles use the same base motor.

 

Great write up!
