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.

    Every time the car starts I hear a clicking coming from behind the dashboard. It clicks for about 1 minute and then stops. I don't hear it again until the car is started again. If I start the car and then turn it off the clicking continues for about a minute and then stops.

    Once I start the car, I hear a clicking noise from the behind the dash. When it started it was only about 45 seconds, now it is going on for about 1 1/2 minutes to 3 minutes. Now I hear at least two motors clicking. It affects the AC and the Heater function, to the point that the AC will run by itself when turned off, Half my windshield will not defrost (Passenger side) and I believe it has affect the entire AC system.
