my drivers side power window wasnt working very good when i went for a drive after taking my camaro out for its weekly ride. this only happens when its colder outside i'd say 35 or below. the window will go down very slow and then go up slow or not at all, i know this is a common problem, but before i take the door panel off, i d like to have replacement parts ready. fyi, i chaged the switches already. so im thinking its the motor or actuator, or maybe its just out of line.

thanks

 

Or maybe you just need to replace the old nasty grease!!
