2003 Chevy impala heater/ac
I have replaced my blower motor resistor and
blower motor checked all the fuses and still yet not
able to find why my heater/ac only turns on when
it wants to. Any suggestions on how I can resolve
Sounds like a faulty control head.
@cjsras but the ac/heater control panel all the lights turn on and even the back window defroster works I checked the air and vacuum hoses they are fine
That tells me the lights work, not the switch for the blower motor.
I replaced the whole panel and still nothing
