Electrical issue? Got a stumper here!!
Iíve got a stumper here. I have a 2003 Z4 (50k miles) and have an intermittent recurring issue. Seems to happen after it rains. The issue is that the following things stop working until I unhook the battery for a couple hours so the computer can reset: Top, windows, radio(powers on but no sound), signal lights (flash on the car, but not the dash), AC.
Once it resets, itís fine until the next time. Could be days, weeks or months later.
