jdreda Posted December 18, 2009 Share Posted December 18, 2009 my wife has a 2004 tahoe with the dual climate control (not the computer) and she is strarting to get angry that i have not figured this problem out yet. I thought maybe it was the controller so i bought another one and notta. is there two heater cores in the front or one. I am this close to taking it to the stealer and have them tell me what it might be. But if anyone has had this prob before or might know what it might be i would greatly appreciate it and so would my newborn baby girl. Link to comment Share on other sites More sharing options...
