Circuit Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The intermittent switch in the windshield wiper washer switch is a voltage divider connected across the body control module (BCM) inputs circuits windshield wiper switch signal circuit and windshield wiper switch low reference circuit. The front wiper relay is energized by the BCM switching the front wiper relay control circuit to ground.
The intermittent wiper delay switch has 3 switch positions.
- Delay 1 (500 ohms resistance)
- Delay 2 (1000 ohms resistance)
- Delay 3 (2000 ohms resistance)
Refer to Wiper/Washer System Description and Operation for the timing of each delay position.
