SOURCE: rear heat in 2004 gmc
I have a 2006 yukon and have had to replace the actuator in the rear heat/ac twice. It moves a valve that closes the cold/hot ducts. It is a cheap defective part/design.

There is a widespread problem with electrical shorts with the seat warmers. I bought the extended warranty through CarMax and theyy fixed it. Retail repair cost on that would have been $900+. It may be covered by GMC via a recall, but only if you raise enough hell.

Code po449 is the canister vent valve solenoid error.This is a common problem with these valves because they are under the truck in the rear by the spare tire and they get all the dirt and water and snow,if you live in an area where you get snow.You will find it on the canister under the vehicle by the spare tire.
