1992 BMW 325i Q&A
1992 BMW 325i Question: My front power windows don't work at all.
Check for power and ground at the driver side control switch using a meter or a testlight. Also check for switching if there's power and ground. If there's no power or no ground, you have to check out that part of the circuit. If OK so far, and not action at the front windows, then you need to check to see if there's power and ground switching at the window motors.
