A repetitive clicking noise from behind the center area of the dash panel is usually caused by a broken stepper motor actuating arm. The actuating arm controls the direction of air flow in the climate control system. Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

I have the same problem with my 2004 Mercedes CLK500. Noise coming from behind the center console.
Clicking noise that seems to be coming from the center of the dashboard, upon start up. After a few minutes the noise disappears. My Service Advisor mentioned that it is coming from the AC/Heater system, flapper. In time, the noise has disapated There has been no effect on the performance of the system. At 115,000 miles, I'm getting another noise that also sounds like rapping from the front dashboard. You get to live with it.

I was advised not to try to pull the dash apart to fix this, after a few months it went away, or sometimes still heard but very quietly and short lived.
