FRONT
An electrically operated intermittent front wiper and washer system is standard factory-installed safety equipment on this vehicle. The wiper and washer system includes the following major components, which are described in further detail elsewhere in this service information:
- Body Control Module - The Body Control Module (BCM) (also known as the Common Body Controller/CBC) is located beneath the instrument panel on the passenger side of the vehicle. Description and Operation.
- Front Washer Nozzle (3) - Two fluidic front washer nozzles with integral check valves are secured by latch features to dedicated openings in the hood panel near the base of the windshield.
- Front Washer Plumbing - The plumbing for the washer system consists of rubber hoses, plastic tubes and molded rubber or plastic fittings. The plumbing is routed through the engine compartment from the washer reservoir. The front washer hose is routed along the left fender ledge to the hood hinge, then across the underside of the inner hood panel reinforcement to the washer nozzles.
- Front Wiper Arms And Blades (5) - The two front wiper arms are secured with nuts to the threaded ends of the two wiper pivot shafts, which extend through the cowl plenum cover/grille panel located near the base of the windshield. The two front wiper blades are each secured to their wiper arm with an integral latch, and are parked on the glass near the bottom of the windshield when the front wiper system is not in operation. The left and right wiper arms and wiper blades are unique and are not interchangeable.
- Front Wiper Module (4) - The wiper pivot shafts are the only visible components of the front wiper module. The remainder of the module is concealed within the cowl plenum beneath the cowl plenum cover/grille panel. The wiper module includes the wiper module bracket, three rubber-isolated wiper module mounts, the wiper motor, the wiper motor crank arm, the two wiper drive links and the two wiper pivots.
- Multi-Function Switch (6) - The multi-function switch is located on the steering column, just below the steering wheel. Only the switch control stalk extending from the left side of the steering column is visible, while the remainder of the switch is concealed beneath the steering column shrouds. The multi-function switch provides all of the driver controls for both the front and rear wiper and washer systems.
- Steering Angle Sensor - The Steering Angle Sensor (SAS) is integral to the clockspring. The SAS is a Local Interface Network (LIN) master node and a gateway to the Controller Area Network (CAN) data bus. Description.
- Steering Control Module - The Steering Control Module (SCM) is located within the multi-function switch housing on the top of the steering column, just below the steering wheel. Steering Column Module - Description.
- Washer Pump/Motor - The reversible electric washer pump/motor unit is located in a dedicated hole in a sump area on the lower, rearward facing surface of the washer reservoir, on the back of the cooling module just to the left of center. This single reversible washer pump/motor provides washer fluid to either the front or rear washer system plumbing, depending upon the direction of the pump motor rotation.
- Washer Reservoir (1) - The washer reservoir is located in the engine compartment on the back of the cooling module just to the left of center. The cap is accessed from the front of the engine compartment.
Hard wired circuitry connects the front wiper and washer system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the front wiper and washer system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
