Rear Window Wiper Motor
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The rear window wiper motor contains a logic module, an integrated relay and a single speed motor. When the windshield wiper motor momentarily energizes the integrated relay within the rear wiper motor, the rear window wiper is activated. The internal logic motor is used to continue the rear window wipe and park the wiper motor.
