I've noticed this since I've had my car. My power windows are really slow, they probably go up and down half as fast as they should. I have a 2 door, 2005 LS. Unless I was given 2 bad motors, what else could it be. I haven't had any electrical power trouble, and my battery is the original one from GM. Thanks :)

Lubrication of the rails. Grease has dried up. Just need to clean and relubricate. Once you have it apart you will see where it is needed.

Sweet, thanks :)

I guess they NEVER lubricated them when they assembled the car, or just didnt lubricate them enough . . . thanks again :)

They lubricate thembut the grease dries out with time. The change is so gradual that you think it's normal until you see somebody else's go up and down real quick.

I guess you have to pull the inner door trim to do that....
What type of grease would you use to lub the rails...

White lithium I believe, make sure it is good to -40°C (-40°F).
