Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Wiper Motor
The Wiper Motor has two B+ connections, one for slow speed operation and one for fast speed. The ground side of the wiper motor includes a reset contact that sends a ground signal to the BC1 once per revolution of the motor. This reset contact is used for park positioning and stall protection.
When the wiper motor is in the park position, the reset contact is an open (High) circuit. The wiper on/off relay will be de-energized if the reset contact does not go High at least once every 18 seconds.
