I have a 1994 Buick Century and when I first got it the dealership replaced the window motor on the passenger side and it worked for a while but it seemed as though all of the power going to it went out and it got slower and slower going up and now it is stuck about one inch from being rolled all the way up. Should I replace the motor and regulator again or could it be a wiring problem or both because all 3 of the other windows work fine except that one and there is no power going to it at all. I think its possible that even after you pressed the button to roll it up that power was still going to it and burned the motor out. How can I fix my problem. Thank you for all suggestions.
