Hello,

Got in car and fan wasn't working on any setting. While driving I was screwing around with the knob because that's been the issue in the past (I've replaced that switch numerous times over the years). Knob was fine. As I am putting the knob back on while driving I went a little off the road and hit a bump. Fan starting working. Ummm... obviously I have a short somewhere. Any Suggestions as to where to look?
