Ac heater control
How can you tell if the air conditioning/ heater control panel is bad? I had a forum member replace the burned out bulbs with led ones a few years back. Looks great. Now no matter what switch is used there seems to be no control action at all. Any help would be greatly appreciated

No action, or no air switching? If you turn up the fan do you hear more noise, just without more detectable air flow? A/C light illuminate?
if lights switch on and off, and you can change the noise level from the fan, you’ve lost vacuum signal to the control actuators.
