No Heat On Driver Side

[jdreda]

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.

sounds like your blend doors are not working. not a uncommon issue..

 

good luck

If it is the door see this. The drivers side is the easy one.
