My defrost, cruise control, heat control knob (where to adjust where the heat goes I.E feet, head.) &Amp; odometer all went out at the same time while I was driving In my 2005 chevrolet cobalt ls. What is a possible reason for this problem. I tried replacing fuses & that didn't work. Please help me!
Pul the fuse for hvac for 60 seconds with key on it may reset the control head for heat. Cruise control can be a switch or relay and if fuse is good underhood it shold be checked by a pro as I will need scanning. Same with heater if fuse doesn't fix it.
