So...when I bought my '93 325i, the mechanic i had check it out told me that the rear window didn't work. Ok, whatever, it's 12 years old, shit happens. I figured the motor was shot because when i push the button for that window to go down, i didn't hear any sound whatsoever (it could also have been other things, but I went with the motor). I found a used motor on ebay for $30 (shippedw/regulator). So I take my door panel off and I look at the old motor. The wiring is unclipped. So...I clip the wiring back to the motor, turn the key and roll the window down like a charm. YAY! so I go to roll the window back up, and nothing. not even a sound from the motor. What do I do?? I don't know how to remove the pop rivets either. I've read on the forum you have to "drill them out"?? how do I do that? what kind of drill do I need? I hate electrical shit. let me know if you can help.
