Im heaving trouble with my electric windows in my 88 gmc crew cab. Question is are the back seat window motors the same at the front one? Or do they get their own motor?
-
I would think they have their own motors, could be wrong on this, but logic tells me they have their own. Someone will chime in and be able to say for sure. Did you check to see if the buttons were giving you trouble ?

Im going to rebuild all the windows. Felt kits and buttons. I have a new front motor and wondered if it fit in the rear one.
-
The actual motors are the same. The lifts are not.

Not to threadjack, but what actually causes the slowness in these old power windows? Do the tracks somehow... get slightly bent or something? I hosed down my drivers side tracks (fully) with WD-40 about a year ago and so far they're running a little faster than they were. But only a little. Its like its struggling to get the window up.

bent track/alignment, worn weatherstripping, OLD motors...

That is exactly right. Old motors, worn stripping, bent or alignment problems will cause your windows to not work right or struggle. Also the motors are the same. The best thing, even though it is a kinda of long process, is to completely disassemble the window parts, clean everything, check to make sure that all parts are not bent or over worn. Replace and seals and/ or weatherstripping that need it. Put it all back together again and lube the parts. I recommend using white lithium grease, it won't freeze in the cold, it won't rust, and it will use any grease that is created from operation to keep the parts lubed. Also be sure to make sure that all electrical connections are correct and well connected. I also recommend while you are cleaning the parts to spray all electrical connections with electrical CONTACT cleaner. You can even spray inside the switches. Be sure to use electrical CONTACT cleaner and not electrical PARTS cleaner. Parts cleaner will actually erode and eat apart your plastic switches and harnesses right in front of you and then you will be corked. Best of luck! This process also works with manual windows, (just without the electrical of course), and electric or manual door locks. :)
