Wiper/Washer System Description and Operation: Notes

The windshield wiper/washer system consists of front and rear wipers. The front and rear wipers are operative when the vehicle is in accessory or run. The front wipers have 4 different modes. The 4 modes are MIST, Intermittent, Low and High. When the front wipers are in the intermittent mode, there are 3 delay modes to chose from, commanded by the windshield wiper washer switch through the body control module (BCM). There is one mode for the rear wipers. The rear wipers has an intermittent mode only and the intermittent mode has 3 delay modes to chose from. The wipers are powered through the windshield wiper washer switch except for the intermittent mode. The intermittent mode is controlled by the BCM. The front and rear wipers also have a washer function. By putting the wiper switch in the wash mode the front or rear wipers will spray washer fluid on the windshield and the wipers will then clean the windshield, wipers will be controlled by the BCM.
