I have a 1989 325i and I did a engine and transmission swap on the car everything was working fine for about 3 months. The other day I hit a bump and I lost my heater/fan and power windows. I had to turn off my car and start it back up and it (I guess) wiggled a wire and I got my power back to the windows and heater. I figured it was a ground wire lose, but I do not know where to look. Any suggestions on where to look for this lose ground wire would be great.
Thanks
