AC/Heater Full hot only!
My AC/Heat only blows full hot air on any setting. It's a 2007 with only 5K miles, so I suspect the heater door might be stuck full open. I don't have a clue where to start looking.

It's difficult to troubleshoot without a TechII. It could be as simple as the HVAC control module just below the Nav unit failing, or failed.
Here is the service manual section for that system. It explains the system and how it works and the components that divert and adjust temps. It's at then end of the section starting on or around page 146.
Good Luck.
