Important Installation Notes:

Many vehicles have multiple HVAC door actuators installed in different positions throughout the climate control system. Each actuator serves a specific function and location. Before ordering, verify that this part matches the exact position and function of the actuator you need to replace by reviewing application notes for your specific vehicle year, make, and model. This actuator is designed for temperature control (blend door) applications and may be used in either main or auxiliary HVAC unit positions depending on your vehicle configuration.

Common symptoms of a failing blend door actuator include inconsistent temperature control, heat or air conditioning working on only one side of the vehicle, defrost malfunction, or clicking/tapping noises coming from behind the dashboard when adjusting temperature settings.
