2004 Chevrolet Tahoe Q&A
2004 Chevrolet Tahoe Question: Heater blows cold only in back of vehicle
I see a mode door actuator for the rear auxiliary air cond , temperature door and also a temperature control assembly available from the dealer or parts.com go to auxiliary air cond and click on auto temp control. Only way the heater core is bad is if it leaks. - hemicuda
Could the heater core be stopped up? should I try flushing it?
