The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Clicking Noise From Behind Center of Dash

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.
