

Electro Mechanical Instrument Cluster - The Electro Mechanical Instrument Cluster (EMIC) (also
known as the Cab Compartment Node/CCN) is located on the instrument panel directly in front of the
driver. Refer to DESCRIPTION .



Front Washer Plumbing - The plumbing for the washer system consists of rubber hoses and molded
rubber or plastic fittings. The plumbing is routed across the front of the engine compartment to the right
side of the engine compartment from the washer reservoir on the left side of the cooling module, and
through the cowl plenum panel to the underside of the hood panel and 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 equal length front wiper blades are each secured to their equal length
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 (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 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.



Right Multi-Function Switch (6) - The right (wiper) multi-function switch and the left (lighting) multi-
function switch are secured to brackets integral to the clockspring housing on the top of the steering
column just below the steering wheel. The right multi-function switch is connected by a short jumper
harness to the Steering Control Module (SCM), which is internal to the left multi-function switch
housing. Only the switch control stalk extending from the right side of the steering column is visible,
while the remainder of the switch is concealed beneath the steering column shrouds. The right multi-
function switch is dedicated to providing all of the driver controls for both the front and rear wiper and
washer systems.



Steering Control Module - The Steering Control Module (SCM) is internal to the left 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 left 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. Refer to DESCRIPTION .



Totally Integrated Power Module (2) - The Totally Integrated Power Module (TIPM) is located in the
engine compartment, near the battery. Refer to DESCRIPTION .



Washer Pump/Motor - The reversible electric washer pump/motor unit is located in a dedicated hole on
the lower outboard side of the washer reservoir, on the left side of the cooling module fan shroud. 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 integral to the coolant reserve bottle, which sits astride
the fan shroud of the cooling module. The reservoir filler cap is accessed from the left front corner 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.
