An electrically operated intermittent wiper and washer system is standard factory-installed safety equipment on this
model. The wiper and washer system includes the following major components, which are described in further detail
elsewhere in this service information:

•

Check Valve - The washer system check valve is integral to the wye fitting located in the washer plumbing
between the cowl plenum washer hose and the washer nozzles, and is concealed beneath the cowl plenum
cover/grille panel at the base of the windshield.

•

Front Control Module - The Front Control Module (FCM) is integral to the Integrated Power Module (IPM)/
Power Distribution Center (PDC). The FCM/IPM/PDC is located in the engine compartment, near the battery.
(Refer to 8 - ELECTRICAL/POWER DISTRIBUTION/INTEGRATED POWER MODULE - DESCRIPTION).

•

Instrument Cluster - The ElectroMechanical Instrument Cluster (EMIC) is also referred to as the Cab Control
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. (Refer to 8 - ELECTRICAL/INSTRUMENT CLUSTER - DESCRIPTION).

•

Multi-Function Switch (6) - 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 wiper and washer systems. (Refer to 8 - ELEC-
TRICAL/LAMPS/LIGHTING - EXTERIOR/MULTI-FUNCTION SWITCH - DESCRIPTION).

•

Washer Fluid Level Switch - The washer fluid level switch is located in a dedicated hole on the lower, rear-
ward facing surface of the washer reservoir in the engine compartment.

•

Washer Nozzle (4) - Two fluidic washer nozzles are secured with integral latch features to dedicated openings
in the cowl plenum cover/grille panel located near the base of the windshield.

•

Washer Plumbing - The plumbing for the washer system consists of rubber hoses and molded plastic fittings.
The plumbing is routed along the right side of the engine compartment from the washer reservoir, and through
a trough near the right end of the cowl plenum cover/grille panel into the cowl plenum to the washer nozzle
fittings.

•

Washer Pump/Motor - The electric washer pump/motor unit is located in a dedicated hole on the lower, rear-
ward facing surface of the washer reservoir in the engine compartment.

•

Washer Reservoir (1 or 2) - On all models except the SRT-10 and those with an optional diesel engine, the
washer reservoir is combined with the engine coolant reserve bottle secured by integral mounting tabs and
screws to the right side of the cooling module shroud in the engine compartment. This combined reservoir has
separate, clearly identified washer fluid and engine coolant filler caps that are accessed from the right front
corner of the engine compartment. On SRT-10 models and those with an optional diesel engine, the washer
reservoir is separate from the engine coolant reserve bottle and is secured by screws to the back of the
upright left vertical member of the radiator support in the engine compartment. This washer reservoir filler cap
is accessed from the left front corner of the engine compartment.

•

Wiper Arm & Blade (5) - The two wiper arms are secured with integral latches to the serrated ends of the two
wiper pivot shafts, which extend through the cowl plenum cover/grille panel located near the base of the wind-
shield. The two 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.

•

Wiper High/Low Relay - The wiper high/low relay is an International Standards Organization (ISO) micro relay
located in the Integrated Power Module (IPM)/Power Distribution Center (PDC) in the engine compartment
near the battery.

•

Wiper Module (3) - The wiper pivot shafts are the only visible components of the wiper module. The remain-
der of the module is concealed within the cowl plenum area 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.

•

Wiper On/Off Relay - The wiper on/off relay is an International Standards Organization (ISO) micro relay
located in the Integrated Power Module (IPM)/Power Distribution Center (PDC) in the engine compartment
near the battery.

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 har-
ness connectors, splices and grounds.
