Wiper/Washer System Description and Operation: Notes
WARNING: This page is about a different car, the 2005 Saturn L300. However, it is still accessible from the selected car via links, so may be relevant.
The wipers are operative when the vehicle is in ACCESSORY or RUN and have 4 different modes. The 4 modes are MIST, Intermittent, Low, and High. When the wipers are in the intermittent mode, there are 3 delay modes to chose from, commanded by the wiper switch through the body control module (BCM). The wipers are powered through the wiper switch except for the intermittent mode. The intermittent mode is controlled by the BCM. By putting the wiper switch in the wash mode, the wipers will spray washer fluid on the windshield and the wipers will then clean the windshield. The wipers will be controlled by the BCM while in this mode of operation.
