Question about 2004 GMC Sierra
My ac is blowing hot air and the selector buttons for the unit are not lighting up and appear to not be working. checked fuses and found on blown to my trailer brakes and one blown to the cig lighter. problem seems to be electical but I do not know where else to check.
If the compressor will not come on and the freon level is ok, (blower motor working etc..) check the AC Relay or the AC thermostat...both are much cheaper "possible" fixes I

Hi,I am going to try and help you.This could be a problem in the ac system not allowing the ac system to operate.This could be freon loss,But needs to be checked out by a ac mechanic to tell exactly what is causing the problem.The ac may have to be reset,if this is the case.If I can be anymore helpful,please feel free to notify email@example.com.
