My window on the driver’s side of a 2000 GMC sierra has trouble going up. It will get about 3 or 4 inches from the bottom and stop then I have to grab the window, and help it the rest of the way up. I thought it was the motor going out because it has done it since I got the truck about 4 years ago and has just recently got worse. I know the window has been replaced by the prevous owner. After I got the new motor in it still does the same thing if not a little bit worse. I know I was careful with the regulator not to get it bent up. And I greased the track that it slides on. It is almost like it is not getting enough power to the motor. But I am just not sure what to do now that the new motor didn’t fix the problem. Any help would be much appreciated.
