The window in our 96 F250 would not go up yesterday. Today I removed the door panel and pushed the button. I could hear the motor trying to work. I then smacked it with a body hammer and it started working again fine. I removed the motor and hooked it to a battery and it sounds good and works. Normally I would just replace it to be safe. However, we are under a serious budget restraint at the moment. I would prefer to find a reasonable alternative. Is there something I can do to “freshen” up this motor? If I lube the regulator real well would it make a difference? This is the first window motor I have worked on in years. SO I may need some reminding about a few things.
