Rear Door Fans

Rear Door Fans
The rear door fans are driven by a variable speed DC motor. The fans in the rear doors are supplied from the ACC control module with approx. 5-10 V.

The rear-door fans are switched on in AUTO mode when outside temperature drops below +14 °C (5 7°F). They can also be manually controlled using a button on the ACC control module panel or using a button between the seats if there is no ACC.

The fan motors have a fixed minimum speed. Fan speed is then controlled in stages depending on ventilation fan speed.

When the electrically heated rear window is manually switched on the rear door fans always work at maximum speed.
