Driver's Window Acting Wonky

[Donf]

I realize this is a common problem area but I can't find a thread that matches my problem exactly.

Down seems OK but when I try and roll it up it moves up a few inches and then stops. Repeated pushing the button does not induce compliance but ignoring it for a few minutes will, eventually, get it to move up again. Usually just a few more inches, sometimes I get a good 4 inches, but regardless of the amount it stops I have to play the up a bit, wait a few minutes , up a bit, wait, repeat as needed until it finally is up all the way.

Looking at what I find online, it seems that I must be getting power for it to work at all, so I guess I can ignore that step.
To me it seems that:
1) the motor may be "overheating" (can they really do that?)
2) I just need to clean and regrease the tracks with lithium grease (that seems to easy to be true)
3) When they give you problems just replace the whole regulator assembly (I haven't been able locate OEM part yet and generally hesitate with Chinese parts)

Any any thoughts before I take the door apart?

Window motors have an easy life rolling the window down but the weight of the window and the resistance of the regulator and channels makes it rough on them. Don't ASSume you have good power and ground, check it. System works by the switch reversing the power and ground to the motor for the direction the motor runs. Going into the door of these is a life changing experience. Been a while since I worked on one of these window motors but I'd check to see if you can change the motor without pulling the regulator, might have to drill the panel. The regulator uses a big spring to assist the motor in raising the glass. If the regulator is attached to the glass you can remove the motor if you support the glass and put a new one on. If you remove the regulator you must remove the spring or clamp the arms of the regulator before removing the motor or it will chop your finger off.

If you grab the window and attempt to lift one side only, does the glass 'feel' properly aligned in the guide tracks? Is there any significant play, when you perform this action?

Well. That looks like a fairly easy thing do do, so I guess that's my next step.

It looks like it, after changing the mirrors with the harnesses too short I figured GM owed me a simple me. Should have known better

Pretty much anything that might remove fingers is a no-no . Just had my hands worked on and they are nearly back to normal. I use them for my work. Might have to just replace the regulator/motor assembly/ Aisin OK if I can't find OEM?

No. First thing I tried was to see if it was loose or crooked.

Do some google and youtube on regulator/motor replacement. In some engineers dream they decided to make the inner door removeable with everything attached probably for assembly line ease with the door laying flat on a stand. Not a good idea for field service.
