    Focus on the blend door actuator. If you have Electronic Air Temperature Control (EATC), run the diagnostics and record any codes. Afterwards, turn the system off, without saving any codes. This may clear any non-fault codes and allow everything to work normally.

    Try back flushing the heater core. Sometimes that helps. But do not flush engine.
