Rear Washer Hoses/Tubes

Fig. 3 Rear Washer Plumbing:

REAR WASHER HOSES/TUBES
The rear washer plumbing consists of small diameter rubber hoses and molded plastic in-line connector fittings. The washer reservoir hose is connected to the barbed outlet nipple of the rear washer pump/motor unit below the left front wheel house extension and routed up the washer reservoir filler neck to the engine compartment. Just rearward of the washer reservoir filler neck in the engine compartment, an in-line connector with barbed nipples joins the reservoir hose to the engine compartment hose. The engine compartment hose is routed along the top of the left front fender wheel house to the dash panel. The engine compartment hose passes through a hole with a rubber grommet in the dash panel into the passenger compartment.

Below the instrument panel in the passenger compartment near the left cowl side inner panel, another in-line connector joins the engine compartment hose to the A-pillar hose. The A-pillar hose is routed up the left A-pillar to the headliner. At the headliner, an in-line connector joins the A-pillar hose to the headliner hose. The headliner hose is routed above the headliner and along the left roof side rail to the rear of the vehicle. At the rear of the vehicle, the headliner hose is routed above the headliner and along the upper liftgate opening panel toward the right side of the vehicle. The headliner hose then passes through a hole with a rubber grommet in the upper liftgate opening panel and through another hole with a rubber grommet into the upper inner liftgate panel to the rear washer nozzle.

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

Washer fluid in the washer reservoir is pressurized and fed by the rear washer pump/motor through the rear washer system plumbing and fittings to the rear washer nozzle on the liftgate outer panel above the liftgate flip-up glass. 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
