I have a 92' E36 with power windows. The windows first off were going up and down without the key in the ignition. I thought weird. But now the windows wont go up or down without one of the doors open. If i open any one of the 4 doors the windows go up and down just fine. If i close all four doors the windows wont budge. Any ideas on where to start? I would imagine it would have to be a short somewhere but theres only like 500 miles of wires in these cars.
