I think my Grandsons truck is haunted. Here is a list of things that suddenly went out. The HVAC, Fuel Gauge, Cruise Control, 4WD, Heated Seats, Odometer, Oil and Temperature Gauges all went out. He said one day he accidently hit the washer switch and everything came back on, but went out again a short time later. I don't know if that has anything to do with it or not, just trying to fully describe everything he told me. Could it be a loose ground or something?? :?
