Wiper Relay: Service and Repair

Wiper Relays, Front Wipers

Wiper Relays:

The wipers are controlled by two relays, located in the engine compartment fuse box. These are wired in such a way that one relay will run the wiper when energized, and stall it when de-energized (Front Wiper-Run/Park Relay).

The other will select either fast or slow speed on the wiper motor (Front Wiper-Fast/ Slow Relay).


Rear Wiper/Washer System
The rear wipe/wash system is relay controlled and operational with the ignition in position 1. The relay for the wiper motor is fixed to the backside of the A post fuse box and cannot be replaced. The rear wiper/washer system includes the following components:

- Wiper/Stalk Switch
- Rear Wiper Motor
- Rear Wiper Relay
- Shared Washer Pump


The Rear Wiper Motor is attached to the Tailgate.





The Rear Wiper Relay is integral to the passenger compartment fuse box and cannot be serviced separately.

Headlamp Wash System
The headlight wash system is available as an option. An external relay in the A post fuse box is controlled by the BC1. The washer pump and bottle is located in the left front wheel arch area.
