Default Power window slow - motor or regulator?

I finally got in there and fixed my passenger door so the key locks and unlocks it again. While I've got the door card off I figured I should go ahead and fix the power window. The one on the passenger side has gotten slower and slower. It goes down slow but makes it, but you have to help it on the way up and kinda shove it into position while holding the button. Rock auto lists a window motor and a window regulator. Do I need one or the other, or both?


Also taking the opportunity to put Kilmat in the doors

I'd probably start with just the motor, but of course check that the regulator isn't bent or coming apart. I'd also check that it's not getting hung up in the window track. A little silicone grease on the inside of the window track is never a bad idea as long as you're in there.

Ok thanks man. I've never actually had to do any work on power windows before other than just the electrical part. I'll have a look at the regulator to make sure its straight and I'm absolutely sure it needs to be lubricated haha.

First start by cleaning the window's seals/channel, with the window down. Also the edges of the glass, when mostly up. Then spray the seals and channels with silicone spray. Might get a good-enough improvement.

I'll give that a shot, but there's enough slop in the window that I kinda doubt it's the channel. I need to replace the weather stripping and junk, that stuff is all dry rotted to crap. I've got a replacement I need to put in, I've just heard it's a real bear of a job so i keep putting it off haha.

Look at how the window is held in the track. My 89 is funkey and the window rocks in the track. I have to help both of mine, to the top. Clean the track and check the bottom of the window...

Probably at least as bad as a Jeep so worse than a cow.

honda used to have a TSB for this.



the channel was dirty and they also has a "soft guide" that would get dirty AF. like some kinda foamy/clothy material to not scratch the glass and it would basically hold the dirt.



I once cleaned the channels and greased that seal/guide thing and the windows went from "maybe" to "move your hand, its coming up"

Once the window is unbolted and removed, everything cooperates a lot better.
