Intermittent Rear Window Wiper System

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

When the multifunction switch is set to the rear INTERMITTENT position(s), it supplies ground to the rear window wiper motor module input and the wiper 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.
