Intermittent Speed Windshield Wipers

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The 5 intermittent wiper dwell times are activated with grounds controlled by the multifunction switch inputs to the windshield wiper motor module. When in intermittent mode of operation, the wiper motor operates in low speed. Once the windshield wiper motor module receives the necessary inputs from the multifunction switch, it then activates the windshield wiper run/park relay coil and switches voltage through the windshield wiper high/low relay. The high/low relay remains deactivated, supplying the voltage to the wiper motor low speed input and activating the windshield wiper motor. When the windshield wiper motor module receives the grounded input, the motor continues to operate until the Hall-effect sensor senses the wiper motor magnet, which turns off the run/park sensor output to the windshield wiper run/park software, deactivating the relay and disconnecting voltage to the wiper motor. The windshield wipers remain parked until the windshield wiper motor module completes a time-out and then repeats the intermittent windshield wiper cycle.
