The front washer plumbing consists of a small diameter rubber hose (8) that is routed from the barbed outlet 
nipple of the reversible electric washer pump/motor unit on the washer reservoir on the left side of the engine 
compartment side by side with the rear washer hose and the front end module wiring across the cooling module 
at the front to the right side of the engine compartment. The front washer hose is then routed along with the 
front end module wiring across the top of the right front inner wheel house to the cowl plenum assembly where 
they pass through a rubber grommet in the front of the plenum panel into the plenum area. 

Within the plenum area, the front washer hose is connected by an in-line plastic connector to the hood washer 
hose (7). The hood hose is routed through a rubber grommet (5) on left-hand drive vehicles, or through an S-
clip (6) on right-hand drive vehicles out of the plenum area toward the upper hinge bracket on the left side of 
the hood panel (1). Molded plastic routing clips secure the hoses to the upper hinge bracket and the left side of 
the inner hood reinforcement. The washer nozzle hose is then secured within the rear channel bracket for the 
hood silencer on the underside of the inner hood reinforcement cowl between the two front washer nozzles (2). 

A molded rubber tee fitting (3) connects the hood washer hose to the right washer nozzle, while a molded 
rubber elbow (4) connects the hose to the left washer nozzle. 

Washer hose is available for service only as roll stock, which must then be cut to length. The molded plastic or 
rubber washer hose fittings cannot be repaired. If these fittings are ineffective or damaged, they must be 
replaced.

The rear washer plumbing consists of small diameter rubber hose (3) that is routed from the barbed outlet nipple 
of the reversible electric washer pump/motor unit on the washer reservoir on the left side of the engine 
compartment side by side with the front washer hose and the front end module wiring across the cooling module 
at the front to the right side of the engine compartment. The rear washer hose is then routed along with the front 
end module wiring across the top of the right front inner wheel house to the dash panel, where an in-line plastic 
fitting connects the rear washer hose to the headliner hose (1), which passes into the passenger compartment 
through a rubber grommet (2).

inner panel and up the right A-pillar to the headliner (2). The headliner hose is glued to the headliner substrate 
and routed along the right roof side rail to the rear of the vehicle. At the rear of the vehicle, the headliner hose 
passes through rubber grommets and a hole at the rear portion of the roof rear inner header panel and the upper 
liftgate inner panel where it is connected to the rear washer nozzle in the Center High Mounted Stop Lamp 
(CHMSL). 

The headliner washer hose is integral to the headliner unit and, if ineffective or damaged, the headliner unit 
must be replaced. However, the headliner hose can be cut and spliced with a plastic in-line connector fitting to 
facilitate headliner removal without the need to remove the instrument panel. Refer to REMOVAL . 

Washer hose is available for service only as roll stock, which must then be cut to length. The molded plastic 
washer hose fittings cannot be repaired. If these fittings are ineffective or damaged, they must be replaced. 

OPERATION 

FRONT WASHER PLUMBING 

Washer fluid in the washer reservoir is pressurized and fed by the washer pump/motor through the front washer 
system plumbing and fittings to the two front washer nozzles. Whenever routing the washer hose or a wire 
harness containing a washer hose, it must be routed away from hot, sharp, or moving parts; and, sharp bends 
that might pinch the hose must be avoided. 

REAR WASHER PLUMBING 

Washer fluid in the washer reservoir is pressurized and fed by the washer pump/motor through the rear washer 
system plumbing and fittings to the rear washer nozzle located in the Center High Mounted Stop Lamp 
(CHMSL) on the upper outer liftgate panel above the liftgate glass opening. Whenever routing the washer hose 
or a wire harness containing a washer hose, it must be routed away from hot, sharp, or moving parts; and, sharp 
bends that might pinch the hose must be avoided.

The fluidic front washer nozzles (2) are constructed of molded plastic and include an integral check valve. Each 
nozzle has two integral latches (4) that secure them in dedicated holes in the hood panel near the base of the 
windshield. The domed upper surface of the washer nozzle is visible on the outside of the hood panel, and the 
dual nozzle orifices (1) are oriented towards the windshield glass. 

An integral diaphragm type check valve is contained within the body of each nozzle. A rubber seal (3) seals the 
nozzle to the outer surface of the hood panel. The washer plumbing fitting (5) for the washer nozzle extends 
below the hood panel and is accessible from the engine compartment. 

The front washer nozzles cannot be adjusted or repaired and, if ineffective or damaged, they must be replaced.
