it has been going on for a while now, my window sometimes does not want to roll up, for two days i tried but nothing, then today, all of a sudden it works, what can be the prob?
My old 88 had that problem.. I guess the owner after me figured out that some gear inside there had a worn spot, where the window would get stuck in, and the motor couldn't pull it back out.
yeah sounds like the motor, i had one do this and had to change it, got one at a junkyard, like 10 bucks, had another go out and took it out , took it apart, cleaned and regreaced it and bamm!!!!! it was fine
If you can tap on the bottom of the motor and it starts moving, you have a dead spot in the motor. Been down this road many times with the old 65 Tbird, and it worked the same on the 88 mustang.
To verify that the motor is the problem (when its not working), you can watch the voltmeter on the dash and when you push the window switch, the needle will drop. If not, then the problem lies somewhere else.
