My windows goes up VERY slowly especially when it is cold. I tried lubricating the sides of the glass above the actual door panel with WD40 and lithium grease but it didn't do to much. Is the problem down below where I can't get to or is there something else I need to do?

 

Try some dry lubricant, like a silikone spray

 

What do you mean by dry lubricant? I have some silicone grease left over from my sunroof rebuild, would that work?

 

I don’t think so, because it’s grease. Dry lubricant dosn't contain eny grease; when evaporated leaves dry film of lubrication substance, in this case - silicone
