This automotive how-to guide was specifically written to assist owners of the 6th generation (1997, 1998, 1999, 2000, 2001, 2002 and 2003) GM Pontiac Grand Prix in lubricating the fabric & rubber power window tracks and the metal regulator assemblies.

Owners of other General Motors vehicles such as the Pontiac Bonneville, Grand Am, Sunfire, Vibe, Chevrolet Malibu, Chevy Monte Carlo, Lumina, Buick Regal, Oldsmobile Intrigue, and Olds Cutlass Supreme may also find this guide to be useful.

After replacing several of the power window motor & regulator assemblies in my 2001 Pontiac Grand Prix, I realized that friction was the culprit for causing them to fail prematurely.

I purchased some silicone spray lubricant for the window tracks made of fabric and rubber since petroleum based lubricating sprays could break down the rubber over time.

Rubber/Fabric Track

Spraying Silicone Lubricant
For the metal regulator assemblies with steel wires, you'll need a light petroleum based lubricant such as white lithium grease.

If you need instructions for removing the door panels, check my GM Power Window Motor & Regulator Replacement Guide.

Removing the panels requires a Torx T-27 screwdriver and a flat head screwdriver or door panel removal tool.

Spray Into Track Crease
Track Generously Lubed
Lubricate Top Front Corner
If your power windows aren't going up or down as fast as they used to but you don't need to replace a motor/regulator assembly, you can try lubricating the tracks without removing the door panels.

Insert the straw of the silicone spray into each side of the upper window track and spray a generous amount into them.

Then raise and lower the window several times to spread the lubricant on the tracks and edges of the glass.

Spread Silicone With Finger
On the other hand, if you have the time and want to avoid having to buy new window motors and regulators, I'd recommend removing all four door panels to lubricate all of the tracks and the regulators.
7mm Socket & Wrench
Remove Speaker & Mount
Front Speaker Removed
To access the front window track in each of the front doors, you'll need a 7mm socket and wrench to remove the front speaker and mount.

Through the front speaker mount's hole, you can insert the tube of the silicone spray can and lubricate the front track.

Access Hole To Front Track

Lubricate Lower Front Track
Depending on how much silicone lubricant you spray onto the window tracks, some of it may leak out from the bottom of the door panel.

So I'd recommend keeping the doors open for a few hours to allow the silicone to leak onto some newspaper rather than stain your garage floor or driveway.

Regulator Assembly
White Lithium Grease
Spread On Front & Rear
While you have the door panels off, it would be a good idea to add some extra lubrication to the metal surfaces of the regulator assembly and the regulator's steel wires.

Use white lithium grease or some other light petroleum based lubricant.

Top Rubber Lip
GM-Power-Window-Motor-Tracks-Lubricating-Guide-023 GM-Power-Window-Motor-Tracks-Lubricating-Guide-024
Lightly Lubricate Top Lip
To help the windows slide even more easily, I also applied a light coating of silicone spray to the top rubber lip of the door panel and also around the inner borders.

If any of it gets on to your windows, just use some Windex to clean them off.

Re-Attach Door Panel
Torx T-27 Screwdriver
Torx Screw Attached With Tape
Once I was done thoroughly lubricating all of the contact points of each window, I re-attached the door panels by pushing in the plastic rivets and screwing in the two screws with a Torx T-27 screwdriver.

The rest of the pictures on this page cover the same lubrication process for my other power window motor tracks and regulators.


Replacing Motor/Regulator

White Lithium Grease
After lubricating your power window tracks and the regulator, the window should glide up and down relatively easily.

You can maintain the lubrication by spraying a small amount of silicone lubricant down each side of the upper window track every few months.

This should help you avoid having to purchase and install new power window motor and regulator assemblies.
