I'm having intermittent issues with the heat and A/C controller in my 1999 Silverado:
Lights for recirculating and fresh air are both out (one or the other should be on)
A/C light stays on and I can't turn it off
Rear defrost button doesn't do anything
Defrost/dash/floor selector doesn't do anything
Temp selector doesn't do anything, all I get is cold air
The fan speed control DOES work though
Sometimes it works normal, sometimes not. Any ideas?? It's still winter here and I need my heat and defrost!!
