You might have a screw loose. (Never gets old :))


Have you tried adjusting the semi-hidden heat control valve near the passenger side firewall under the hood?

Otherwise, perhaps your blend door actuator.

However, at this point I would suspect your blend door actuator/mix motor Fix or replace. Sometimes the little shaft gets positioned incorrectly, especially if you've recently had it changed.





Could also be your heater control valve. It's a common problem, but usually easy and inexpensive to fix. As a matter of fact, try that first.



There's also a top-secret way to check for HVAC DTCs. See the PDF documents below.
