i got an 83 with pwr windows and evertime they are going up or down (really slow) they make a strange humming sound as they go up or down.
is this from the motor or the tracks? do the tracks just need a lube up or something like that? anyway i want it to stop, what do i do?? any info on this would be great, thanks in adance

 

well if they are going up and down slow to begin with- get new motors- its not a fun job but youll like it alot better when its done, when your installing new motors take the regulator assembly out and check it and grease it- if it all looks good then put it back in.

 

Replacing the motors is the last thing you should try. Checking grounds, switches, and greasing the track should be first.

 

well if your motor is whineing- its not going to be the switch, every 80s GM ive ever owned have had motor failures. if they are going up and down slow its a motor problem. usualy when a regulator goes- it makes a clicking sound, but thats just my day to day expeirience at work.
