i have an 89 325i and i recently replaced a broken right passenger window. I don't know if this was when it happened, but the power windows and power mirrors haven't worked since. This car is not running, so i don't know eactly when it happened. i have tried the window lock switch near the shifter and it feels a little weird. could it be the switch? this wouldn't explain the mirrors not working. I have checked the fuses as well, nothing there. I am in the process of doing an engine swap, so i have unplugged some electrical connections under the hood, but i wouldn't think this would affect the interior electronics. The lights, horn, and everything else in the interior still works, so i am wondering if it is a bad relay or something. any ideas?
