Anyone else have a medal 'clicking' noise with AM a/c?

[GPSnV1]

I took in my X for a couple of items, the most irritating being a noise every morning where there is a 'clanking' or medal clicking noise coming from the dash. The noise disappears when I turn off the a/c. I never check this in the afternoon because I have quiet meditation drives in the AM but music when I leave work.

My regular service rep was not in and the substitute was bold enough to say that I didn't know the difference between the noise of a key chain and something from the dash. That reasoning was based on the basis that I use comfort in the AM but the key in the afternoon. I can't wait to write up his review.

Fortunately, I had videotaped several mornings that showed the car in motion and at stop signs and the service rep and the tech have all heard my recordings.

The tech plans to do a cold start tomorrow trying to imitate my normal morning drive so I just wondered if anyone else had run into this. It certainly sounds to me like the motor (gears?) that moves those a/c doors is going bad.
