I have a 2003 Mini cooper s and I was driving down the road and my girlfriend turned on her seat heater. Shortly after she did that the car started to stink and the seat got really hot, so she turned it off. Further down the road I had noticed that both the speedometer and tachometer had stopped working and that none of the lights were on. I checked all of the fuses for both the seat heater and the speedometer/tachometer and all of them were fine. However, my in dash GPS and radio still worked. Any help on what I can do to fix this would be greatly appreciated.
