Sounds like the heater core. You could test it by pulling it out to see it is clogged, but why bother, you might as well replace it. Actually, have the dealer replace it since there is an extended warranty for the heater core failures on these vehicles.

Cheap cheap part:



I guess I need to learn how to do this (haven't look), in case it ever happens to me. Oilhammer says the job is not bad, and the part is super cheap. I was dreading this whole heater core issue, but not anymore...almost tempted to buy one and have it on hand, just in case :unsure:
