None of my ac/heater controls seem to work. The fan is unresponsive (xs) in auto or manual. The fuses are good, under the dash and in the engine compartment, and I switched the fan and ac relays.
Any power to resistor block at heater/blower? If there is perhaps the resistor pack is done. Would try direct power to blower to see if it turns. Anyway work your way back, sounds like your getting there. Climate control units do go bad too so I would not rule that out. Good Luck!
Resistor packs are bypassed when in max speed mode, so I doubt it's that...but check anyway, as maybe something melted in a connector.
The entire hvac control console seems to be dead, the fan the recirc, the heated mirror switch all seem to be dead. normally when you turn the fan knob to auto, you hear noises from behind the dash, blend doors etc. there is nothing, no noises or lights on the knobs. any suggestions
Is there a separate fuse or relay that controls power to the hvac control assembly.
