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:

- ElectroMechanical Instrument Cluster - The ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) is located on the instrument panel above the steering column opening, directly in front of the driver. Instrument Cluster - Description.
- Multi-Function Switch (5) - The multi-function switch is secured to a bracket integral to the clockspring housing on the top of the steering column, just below the steering wheel. The Steering Control Module (SCM) is internal to the multi-function switch housing. Only the control stalk that extends from the left side of the steering column is visible, while the remainder of the switch housing containing the SCM is concealed beneath the steering column shrouds. The switch control stalk has a control knob on the end that is dedicated to providing all of the driver controls for the wiper and washer systems. Multifunction Switch - Description.
- Steering Control Module - The Steering Control Module (SCM) is internal to the multi-function switch housing, which is secured to a bracket integral to the left side of the clockspring housing on the top of 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 housing containing the SCM is concealed beneath the steering column shrouds. Steering Column Module - Description.
- Totally Integrated Power Module - The Totally Integrated Power Module (TIPM) is located in the engine compartment, near the battery. Totally Integrated Power Module (TIPM) - Description.
- Washer Fluid Level Switch - On vehicles with a gasoline engine, the washer fluid level switch is located in a dedicated hole on the lower, rearward facing surface of the washer reservoir on the front of the Front End Module (FEM) carrier (also known as the radiator closure) just to the left of the cooling module. On vehicles with a diesel engine, the washer fluid level switch is located in a dedicated hole on the lower, forward facing surface of the washer reservoir on the back of the left vertical post of the left fender support hydroform just outboard of the FEM carrier.
- 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.
- Washer Plumbing - The plumbing for the washer system consists of rubber hoses and molded plastic fittings. The reservoir hose is routed from the washer pump near the base of the reservoir through a trough integral to the reservoir to the outboard side of the reservoir, then through the FEM carrier (also known as the radiator closure) to the engine compartment where it is joined to the engine compartment hose. The engine compartment hose is routed along the left side of the engine compartment from the FEM to the cowl along with the left headlamp and dash wire harness through a molded plastic trough. The engine compartment hose is joined to the hood hose near the left hood hinge. The hood hose is routed between the underside of the inner hood panel reinforcement and the hood silencer pad to the washer nozzles.
- Washer Pump/Motor - On vehicles with a gasoline engine, the electric washer pump/motor unit is located in a dedicated hole in a sump area on the lower, forward facing surface of the washer reservoir on the front of the FEM carrier (also known as the radiator closure), to the left of the cooling module. On vehicles with a diesel engine, the electric washer pump/motor unit is located in a dedicated hole in a sump area on the lower, forward facing surface of the washer reservoir on the back of the left vertical post of the left fender support hydroform just outboard of the FEM carrier.
- Washer Reservoir (1) - On vehicles with a gasoline engine, the washer reservoir is located on the front of the FEM carrier (also known as the radiator closure), to the left of the cooling module. On vehicles with a diesel engine, the washer reservoir is located on the back of the left vertical post of the left fender support hydroform just outboard of the FEM carrier. On all vehicles, regardless of engine type, the clearly identified washer reservoir filler cap is accessed from the left front corner of the engine compartment.
- Wiper Arms and Blades (4) - The two unique right and left 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 equal length 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 wiper system is not in operation.
- Wiper Linkage Module (3) - The wiper pivot shafts are the only visible components of the wiper linkage module. The remainder of the module is concealed within the cowl plenum area beneath the cowl plenum cover/grille panel. The wiper linkage module includes the wiper linkage module bracket, three rubber-isolated wiper linkage 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 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.
