Wipers And Washers - Description

DESCRIPTION

An electrically operated intermittent 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:

- Multi-Function Switch - The multi-function switch is integral to the Steering Column Control Module (SCCM) along with the clockspring and the Steering Control Module (SCM) on the top of the steering column just below the steering wheel. The multi-function switch is connected to the SCM. 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 the wiper and washer systems.
- Steering Control Module - The Steering Control Module (SCM) is integral to the Steering Column Control Module (SCCM) along with the multi-function switch and the clockspring on the top of the steering column just below the steering wheel. The SCM is completely concealed beneath the steering column shrouds. Steering Column Module - Description.
- Totally Integrated Power Module - The Totally Integrated Power Module (TIPM) is located in the right front corner of the engine compartment. Description and Operation.
- Washer Fluid Level Switch - The washer fluid level switch is located in a dedicated hole on the lower, outboard side of the washer reservoir, ahead of the right front wheel house.
- Washer Nozzle - 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.
- Washer Plumbing - The plumbing for the washer system consists of rubber hoses and molded rubber or plastic fittings. The washer hose is routed along the right side of the engine compartment to the dash panel, then across the underside of the hood panel to the washer nozzles.
- Washer Pump/Motor - The electric washer pump/motor unit is located in a dedicated hole in a sump area on the lower, outboard side of the washer reservoir, ahead of the right front wheel house.
- Washer Reservoir - The washer reservoir is located in the engine compartment ahead of the right front wheel house. The filler neck and cap can be easily accessed from the right front corner of the engine compartment.
- Wiper Arms And Blades - 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 two 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.
- Wiper Module - The wiper pivot shafts are the only visible components of the 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.

Hard wired circuitry connects the 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.
