The heater comes on by itself and won't shut off. The gauges also will shut down and come on by themselves. It also sounds like a short in the speakers sometimes.

Changing the ATC (automatic temperature control) will clear all of these problems. it is a known issue that the guages, lights, radio, temparature are operated by the box. When the box is replaced all will clear up. I did this 4 years ago and have not had another problem.
