Replaced the switch first on mine because th ePO had spilled some sort of black, sticky stuff on it. Douched it with electrical cleaner and the window went up and down aa few times, but always stopped in the same pace and wouldn't move. Changed to a brand new switch, same issue. Gotta be the motor has a dead spot in it. I hate doing window regulators... lol

IF the motor had a dead spot it will happen about 3 times when the window goes up. Each revolution.
35 years in auto electric always check switch first just saying......
