windows

I need to replace the roller things that break and cause the back windows to pretty much fall into the doors, i know that much already. But my drivers side front window still goes up and down straight but it goes really really slowly. is this related to the same thing thats wrong with the back windows or something different? Im going to replace all the rollers to be safe, but while i have the doors apart is there anything else i should look for?

Sounds like your window motor is getting tired.

makes sense, the problem is twice as bad when its cold outside.

Alot of times that has to do with the inside front & back channels. Not the tracks themselves but the bottoms of the window frame (kindof a rubber fuzz lined gasket).
If the window isnt where it wants to be it slows considerably. Never had a motor that got weak, mine were good or bad.
Drive for a couple of days without the door panel cause as SOON as you button it up things start going bad again.
