Hello all, I have an issue where my climate control is not working, its receiving power because the panel illuminates just fine but controls un responsive. recirculate and fresh air lights not on. Dials do nothing.

I have checked all my four of my HVAC fuses - all are good
I checked vacuum and its reservoir - making vacuum and reservoir is sealed and holding pressure
Checked lines under dash - just dandy
Checked blend door switch - its good

Im running out of stuff to look at and if any of yall had this problem help would be appreciated.

 

The illumination circuit could be different than the control circuit.

I don't like suggesting throwing parts to fix problems but perhaps a trip to a wrecking yard for a replacement control panel might be worth trying?

 

Christine is correct, the illumination circuit provides power to the hvac controller indicator lights from a separate power source. Note there are 5 fuses in your hvac system.
