If that is the case, you wouldn't be the first to get fooled by that DAMNED BUTTON! I have a thread on here from last summer where a buddy of mine that had owned an e30 before pushed that button and I had to drive 50 miles each way to work and back for about 3 days in Atlanta, IN SUMMER, WITHOUT AC!!!!!!! I was such a noob!
Just check the black button above the OBC to see if you can see the orange/red outline at the back. If you CAN, push it in, and your windows SHOULD work!
