If your car's A/C is blowing the wrong temperature or the air won't switch between the face, feet, or windscreen vents, a faulty HVAC actuator could be the cause.
🔧 Temperature actuator – Controls the blend door to adjust hot and cold air.
🔧 Direction (mode) actuator – Controls where the air flows (dash vents, floor, or defrost).
Common symptoms: • Clicking noise behind the dashboard • Incorrect air temperature • Air coming from the wrong vents • Inconsistent airflow
A proper diagnosis can save you from replacing the wrong parts.
