Rear Window Wiper and Washer - Taurus X

WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.

When the multi-function switch is set to the rear wiper intermittent position(s), it supplies ground to the rear window wiper motor module inputs and the wiper motor operates in intermittent mode. During intermittent operation, the rear wiper motor momentarily activates the rear window wiper relay (internal) which sends voltage to the motor. Once the rear window wiper motor is activated, the internal run/park switch connects voltage to the motor, keeping it operating. When the rear window wiper motor returns to the PARK position, the run/park switch disconnects voltage internally from the wiper motor input, reconnecting it to the rear window wiper motor module output. The rear window wiper remains parked until the rear window wiper motor module completes a time-out and then repeats the cycle.

If the liftgate is opened while the rear window wiper is operating, it will stop immediately. The rear window wiper will resume normal operation when the liftgate is closed.
