I have a 2004 GMC Yukon that began blowing hot air while the air conditioner was on either from the driver side or passenger side and rear.. alternating between all of those but mostly just blowing hot air from the passenger side.. the mechanics put a new blend door actuator on the driver side and a new control head module in the dash... it didn't help and the new control head sometimes would not even come on... so last week they put a new control head in thinking the other one was bad although it was new.. new control head has work gray all week until yesterday then it begin blowing hot air again and today it will not even come on just like the other one... I will be taking it back to the garage this week but I know they are at a loss as to what the cause is.. does anyone have any advice?
