Control motor for temperature regulating flap 6R0907511C

V68 temperature flap motor.

The main symptom of damaged V68 motor is the blower doesn't blow air at the temperature you've selected. It usually blows hot air when it's set to cold. Restarting the car, or turning the thermostat from fully hot to fully cold can cure the problem momentarily, but it'll soon start to play up again.

The potentiometer in the motor housing is almost always to blame for the motor playing up. Sometimes the problem is broken teeth.
