View Full Version : lube for a slow power window?

04-02-2005, 08:55 PM
well i've gone thru all the old threads of "how to fix a slow power window".
gonna tackle this project tomorrow, windows gettin' pretty slow, especially when it rains. im going to clean all the components, but im not sure which lube to use. i saw dry teflon,graphite powder,garage door lube, and something called window run lube. what would be best? and where is a good place to find it?

since you're going to be taking the interior panels off anyway, you should buy a set of new motors at the local auto parts store. i forgot how much mine were, i could be way off, i think they were around $20-$30 each. well worth the money. i dont have to "help" the window up by hand anymore.

Silicone Spray,or KY jelly :ignore:

i've got one motor replaced already, it starting to slow down as well, especially in the rain. in the old post it said to avoid silicone or lithium grease, anything that attracts dust will gum up eventually. thats why they suggested the dry teflon or graphite powder

Prolly splled wrong but that is the stuff. it comes in a spray can and is like 3 dollars. Get a can and spray it on the window tracks and see if it helps. Worked wonders on my van with same problem.

I usually use motor assembly lube on the tracks if the motor is really tired. GM just uses a thicker version.

If the motor isn't tuckered out I use Maxima Chain Wax. Very good lubricant that doesn't attract dirt.

Usually the root cause of the problem is the plastic rollers on the ends of the scissor arms. As they age, the plastic swells or something and then the roller doesn't roll on its axle any longer. :mad: So instead of smoothly rolling back and forth in the track on the bottom of the glass, they're dragging.

I'd try and smooth up the tracks and clean off any surface rust and gunk, check the condition of that roller, and apply boat trailor axle grease. It's that blue goopy stuff, will stick to it forever and is waterproof.

Clean the tracks, clean the motor gear, clean the channels where the rollers run, and clean the rollers. There are numerous choices on what lube to use, but the thicker the lube, the slower the window, I think the axle grease is a little to thick. I have had very good results with white lithum based grease, and silicone spray the window channels.

I use silicone spray or teflon spray lube on the felt wipers in the tracks--Gunk brand's "Liquid Wrench ll " has teflon and silicone in it,I had good results with that stuff,and it works good on slider window aluminum channels body shop guy I know uses car wax on the window glass edges to prevent them from "dragging" on the felts... :crazy:

just finished with the windows. i got this stuff called RD-50 dry film lubricant. found it at home depot. leaves no residue for dust to collect. great product. sprayed it on all moving parts. works 100% better, even with the cracked/swelled weatherstripping. electric motor is now ALOT happier. :D shoulda done this a long time ago..

Are you thinking of dielectric grease?
