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:

- ElectroMechanical Instrument Cluster - The ElectroMechanical Instrument Cluster (EMIC) is also known as the Cab Compartment Node (CCN) in this vehicle. The EMIC/CCN is located in the instrument panel above the steering column opening, directly in front of the driver.
- Front Control Module - The Front Control Module (FCM) is integral to the Integrated Power Module (IPM). The FCM/IPM is located in the engine compartment, near the battery and the Power Distribution Center (PDC).
- Front Washer Nozzle (2) - Two fluidic 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 and molded plastic fittings. The plumbing is routed along the underside of the Power Distribution Center (PDC) bracket to the engine compartment from the washer reservoir. The front washer hose is routed across the underside of the hood panel to the washer nozzles.
- Front Wiper Arm - The two 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 right arm is articulated by a unique linkage arrangement to increase the wiped area of the windshield glass.
- Front Wiper Blade - The two unequal length wiper blades are secured to the two wiper arms with an integral latch, and are parked on the glass near the bottom of the windshield when the wiper system is not in operation.
- Front Wiper Module (3) - The wiper pivot shafts are the only visible components of the front wiper module. The remainder of the module is concealed within the engine compartment beneath the cowl plenum cover/grille panel. The wiper module includes a cast aluminum wiper module bracket, four rubber-isolated wiper module mounts, the wiper motor, the wiper motor crank arm, the two wiper drive links, the two powered wiper pivots, and a static pivot point that is located outboard of the right pivot for the articulating link of the right wiper arm.
- Multi-Function Switch (4) - The multi-function switch is located on the top of the steering column, just below the steering wheel. A control stalk that extends from the left side of the switch has a control knob on the end that is dedicated to providing all of the driver controls for the front wiper and washer systems.
- Washer Fluid Level Switch - The washer fluid level switch is located in a dedicated hole on the lower, rearward facing surface of the washer reservoir, ahead of the left front wheel house splash shield.
- Washer Pump/Motor - The reversible electric washer pump/motor unit is located in a dedicated hole on the lower, rearward facing surface of the washer reservoir, ahead of the left front wheel house splash shield. 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 combined with the engine coolant reserve bottle located on the radiator support to the left of the air conditioning condenser in the engine compartment. This combined reservoir has separate, clearly identified washer fluid and engine coolant filler caps that are accessed from the left front corner of the engine compartment.
- Wiper High/Low Relay - The wiper high/low relay is an International Standards Organization (ISO) micro relay located in the Power Distribution Center (PDC) in the engine compartment near the battery.
- Wiper On/Off Relay - The wiper on/off relay is an International Standards Organization (ISO) micro relay located in the Power Distribution Center (PDC) in the engine compartment near the battery.

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.
