Clicking sound upon starting the car

[lawyerdement]

I have a 2010 SHO. When I start the car there is a clicking sound in the dashboard on the driver's side. Any ideas as to the cause?

Either the LH blend door actuator or mode door actuator has a broken gear in it. It may continue to work or it may jam in place.

That sounds about right. the only thing moving behind the dash is blend door motor/actuator as far as I recall
