Q: HVAC actuators not working properly

asked by on

The HVAC actuators in my car are clicking and not working properly.

There are quite a few issues reported with the blend door actuator behind the glovebox being problematic. Other possibilities include a faulty BCM (Body Control Module) or damaged HVAC harness. Before having any parts replaced, you may want to enlist the help of a mechanic, such as one from YourMechanic, to inspect your AC system, and properly diagnose the HVAC issues with your Impala.
