There is loud clicking sound that seems to be coming from the AC/heater control panel. it does not matter what position the switch is except between the first and second position. All positions make the clicking sound and each position selected works.

Good morning.

There are actuators that work different controls for the system such as blend door, mode controls and air controls. When the are failing, that is the noise you hear. They may still work but one of the functions will stop working eventually.
