Have any of you guys ever rebuilt your own power window motor? The first one I put in my car of the set is pretty slow. I noticed that already when I tested all 4 out on the floor. I'm tempted to take it apart and see if I can improve the power in it. Any ideas? Does it just need a good cleaning?

I would totally agree with what Michael says, i have had good success with cleaning and good point about the chanels and tracks, they need to move freely

Yes, I did the external stuff earlier. I have learned too that it helps to clean all the old junk out of the channels and put fresh lithium grease in them. Same for the gears, fresh lithium.
I'll see if I have an old motor to learn on. They must not be too complicated I'm thinking.
This one actually seems to move up better than down, so the spring appears to be doing it's job. I'm guessing it's a motor issue.
I did get it greatly improved with track adjustment but it's still not what it should be.

Ah, power accessories, a total pain in the ass, but boy are they cool when they work right!

Yup, I love 'em. Can't live without them!

I used to work with a fellow who worked as a tech at a Cadillac dealer in the 1960's. He said the only part they didn't rebuild back then was the power seat motors. Sounds like power window motors are fair game!

Im old school. Take it apart and service it. Unfortunately you can only service the gears not the motor. They are cheap enough to just buy new motors from Ames.
Note: to get a right front order a left front. Lol
I had to swap there listing left to right. I needed 3 motors and had to buy the 4th because of that.
I suggest you take pics and verify with a rep before ordering.

Sleepy power window check list...
1...misalignment of window tracks
2...repro glass channel and roof rail weatherstrip are common slowdown culprits
3...bad grounding because of repaint of door hinge area (door hinges should be mounted bare steel to bare steel on the door and jam sides)
4...power supply wiring corrosion or tearing (copper shouldnt be green!)
5...poor contacts on switches (rust, hardened grease crud or weak contact tension)
6...weak relay engagement
7...motor corrosion or hardened lubrication on motor gear

Check the end plate opposite the drive end for two small holes (used to insert wire to hold the brushes in for reassembly) some don't have them. They kind of blow apart when you pull the armatures out.
Just cleaning the contacts and re-lubing should wake them right up.
Other issues... If the regulator has been apart... common to not have the spring wound enough (fast down slow up).
