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.

    Used to click from behind dash when started after several attemps the clicking stops. Now it doesn't click anymore but I can't get air to the front vents. Need to replace but haven't done so yet.
