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.

    Under the driver side a damper flaper snper 5x after every start up. After removeing the under dash cover I could see everything. It looks as if a motor or a arm is not moveing the way it should. This is not fixed,can anyone help.

    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.
