HVAC clicking noise

[hertfordnc]

Whenever I change any of the heater controls there is a repetitive clicking under the dash around the steering wheel. click .......click ........click - about once every half second.

It usually goes away when I turn the fan on full blast.

I'm thinking blend door?

I have no experience with this particular problem. I would love to hear from anyone who has a clue.

thanks

It's the motor for the blend door.
