Hey all,
I'm having a problem with my rear drivers side window in that it won't go down. I pulled the motor and regulator out and without the glass attached it works just fine. I figured I'd throw some lube on the appropriate places as a precautionary measure, I'm just not sure what to use. Anyone have any recommendations? Things I know I have handy are white lithium grease, motor oil, and mineral oil (for when I make cutting boards).

Thanks,
Corey

I use silicone grease. Even the silicone based dielectric grease is fine. You'll want to use something like that as it doesn't attract dirt they way other lubricants do. Other than that, of those you have listed, I'd use the white lithium grease.

Both of those greases Archon listed are the only two I'd use in window hardware.

Thanks guys! I just finished putting it all back together after lubing up the slides with some silicone based dielectric grease. It goes up and down now better than all the others combined.
