I've noticed a click...click....click click....click...click noise in the cabin, coming from the dash. It stops when I shut off the climate control and starts again when I turn it back on. A/C and heat work fine. Anybody got a clue as to what it is?

 

May be blend door/vent actuator. Can the climate control station successfully switch from vent to floor?

 

Not sure. I'll check.

 

OK turned on the climate control and changed the mode so the air was coming from the dash and down below. Clicking noise stopped. Thanks for the diagnosis bfsgross!!

 

Awesome!
