Temperature Won't Change

Frequently asked questions
Why is the air stuck hot (or cold)?
The blend door mixes hot and cold air; if its actuator fails, the door stays in one position and the temperature won't change no matter the setting.
Is this a big repair?
Usually it's a blend-door actuator — a moderate part — and sometimes just a recalibration.
