I need help with my power windows. They move up very slowly and go down very fast and off track. The glass is very loose. Need help with doing a full power window resto. I need them to work properly period. Anyone here in the Norwalk/Cerritos/Long Beach, CA area know of a glass shop or a auto shop where they specialize in power windows. Thanks

Hey mate,

If you take your door trims panels off, you can see the window rails on either side of the window inside your door.

They are probably too far apart and thus why your window is loose, you can adjust them by loosening the nut or nuts (10mm i think) and moving the rails in closer to the sides of the window.

From memory there is a stopper at the bottem end of the rail that will help stop the window going down too far, if you take a look you may find that this has moved a bit and will need relocating also.

Go to your local auto parts store and buy a spray can of "Silicone Spray" and spray the felt inside the rails on either side of your window from top to bottom. Silicone spray is the lubricant you use for power windows to keep them sliding easily and should be re-applied every few months or so. Just don't get it on your window too much as it's a bitch to see through.

While you have the door cards off, spray the metal track, rollers and gear with brake cleaner to remove the old lube and accumulated dust. the respray those parts with white lithium grease/lube. Run the windows up and down before making any adjustments. If the glass is cocking on the way up, it's usually due to poor lube and the chanel stripping has hardened and worn.

Be careful with any lube that contains silicone. Overspray makes repainting a bitch. You may wish to concider replaceing the track seals. Pricey but often well worth it in terms of window function and eliminating air leakage.

Three adjusting bolts. One in front. Two behind the rear of the arm rest. The holes for the three adjusting bolts are oblong, unlike the other mounting bolt holes. After you've followed the instructions already given, don't forget to clean the switch contacts.

VB (or whatever their name is currently) sells the white plastic glass holders that are at the bottom of the scissor mechanism. When these break, it allows the glass to cant forward or backward in the track, and could be the cause of your misalignment.

The issue with the motors going faster down than up is partly due to gravity (!), and partly because the switch contacts in the center console have likely gotten corroded and aren't carrying the same juice to run the motor as they once did. Pull the switches out and you can see where the connectors are - clean those contacts and you'll probably get some function back.

Awhile ago, someone posted a tutorial on how to replace the window switches with 12V relays, which takes the amp flow from the switches and puts it on the relays with direct 12V power from the fuseblock. This solves several problems; 1) the current doesn't accelerate corrosion on your switches, and 2) the motors are getting good clean power so window motor speed goes up accordingly.

I wouldn't play with the track adjustment screws too much first off. Clean the tracks, look for broken parts, and be sure to get all the old gunky lube from it before trying to adjust for anything. At this point, if it worked okay for 25+ years, the track alignment is probably just fine!

+1 on cleaning the switch contacts...74RX4 and I fixed MY problem with same symptoms that way...
