Ok so my 2006 MC is making this clicking sound when you adjust the a/c and heat. I've been playing with it to know that it basically starts when I have it set on bringing air from outside vs. circulating the car's air. It also starts making the noise when I turn off the car if the setting isn't on a/c when turned off. It sounds like it's coming from the passanger glove compartment and then other times from the middle of the dash. Please help.

Thanks!
