Help With Dual Climate Control

[dacjac]

on my 04 sierra crew cab this is an intermitten problem with the dual climate control with the ac on the drivers side will switch to heat after about 5 min and the passengers side stays nice and cold if I shut the truck off and restart if it will blow out cold air again and it's ok.

You more than likely need a new actuator. Also, there is a calibration update to help with the actuator limits. That is the easy actuator to change. It is on the bottom of the case.

I stopped by the dealer yesterday, this actuator is $238!
