Function And Symptoms
This servo motor actuates blend and vent doors to regulate airflow direction and temperature mixing. Typical symptoms of a failing unit include repeated clicking noises from the dash, vents that do not change position, incorrect cabin temperature, or loss of certain airflow modes.
Causes Of Failure
Failures are most often caused by worn plastic gears, motor winding fatigue, connector corrosion or moisture ingress. Environmental factors and heavy use can accelerate wear; service life varies by vehicle and operating conditions.
Replacement And Installation
Replacement is straightforward for experienced technicians. Typical steps:
- Disconnect the negative battery terminal to prevent electrical shorts.
- Remove the glove box or lower dash panels to access the heater unit depending on vehicle layout.
- Locate the faulty servo, unplug the electrical connector and remove mounting screws.
- Install the new BEHR servo, secure mounting screws and reconnect the plug.
- Reconnect the battery and cycle the ignition/HVAC controls to confirm correct movement and functionality.
