Intermittent Wipers
WARNING: This page is about a different car, the 2003 Mercury Sable and 2003 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The intermittent wiper speed control allows one of seven delay periods between each wiper swipe. The multifunction switch controls delay by resistors within the switch. This signal is sent to the GEM. The GEM then activates the wiper lo/hi relay at a chosen time interval specified by the multifunction switch. When the relay is activated the wiper motor will operate.
