I have a 2001 boxster s. A few days ago when I started the car the climate control fan stopped working, the headlight low beams would not come on, and the heater seats would not come on. With the car stopped and the engine off, but key on everything works. As soon as I start the car; engine running the same problems return. No fan, not low beams, and not seat heater? Does anyone have an idea what is going on?
