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.
Rear Wiper System Operation
When the ignition switch is in the ON or the START position and the rear wiper switch is activated, the switch mechanism locks the contacts of the wiper switch to the closed position. Battery voltage then applies through the following components:
- The GAUGE fuse
- The rear wiper relay 1
- The rear wiper relay 2
Since the rear wiper motor is permanently grounded, the motor operates as long as the rear wiper switch contacts remain in the closed position. When the rear wiper switch is deactivated, the mechanism releases the contacts to the open position. The contacts release the rear wiper relay 1 and the rear wiper relay 2 provides voltage to the rear wiper motor until the wiper is in the park position.
