Thanks for the motor whack suggestion. Ironically, I was on my way to an appointment yesterday, and the window worked! Of course, I could not turn around and return home. 5 minutes later, it stopped working again. I will try the wack suggestion.

I replaced many manual window regulators, but this is my first power window repair. The regulator seems to work okay, but the motor is sketchy. Did you replace the motor only? Anything specific on the regulator that I should look for, such as bad bushings, slop in the pivot pin, etc?

BTW--The motor/regulator are riveted to the truck door, as well as some bolts/nuts exist on the bottom regulator channel.

When I search for a replacement part on Autozone online, seems I have many choices of motors. Any recommendation between Dorman, Parts Perfect, Siemens, A1Cardone or ARC?
