washer reservoir under the left front fender ahead of the left front wheel to the engine compartment. Both hoses or tubes are attached to their respective
front or rear outlet nipple of the washer pump/motor unit near the bottom of the reservoir. The hoses or tubes are then secured by retainers to the left
inner fender. Just forward of the dash panel (3) in the engine compartment, an in-line connector with barbed nipples joins the rear washer reservoir hose
(1) or tube to the A-pillar hose or tube (2).
The A-pillar hose or tube (1) passes through a hole with a rubber grommet (2) in the dash panel (3) into the passenger compartment where it is attached
to the A-pillar (4) with plastic retainers (6). The A-pillar hose or tube is then routed up the left A-pillar to the headliner. At the headliner, an in-line
connector joins the A-pillar hose or tube to the headliner hose or tube (5).
The headliner hose or tube 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 or tube is routed above the headliner and along the upper liftgate opening panel toward the right side of the vehicle. The headliner hose or tube 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 or tubing is available for service only as roll stock, which must then be cut to length. The headliner washer hose or tube is integral to the
headliner and, if ineffective or damaged, the headliner unit must be replaced. The molded plastic washer hose fittings and routing clips cannot be
repaired. If these fittings or clips are ineffective or damaged, they must be replaced.

The headlamp washer system plumbing consists of a large diameter high pressure rubber hose that is routed from the outlet nipple of the headlamp
washer pump/motor unit on the washer reservoir to one barbed nipple of an elbow fitting near the front upper outboard corner of the reservoir. One end
of a hose from the front fascia connects to the other barbed nipple of the elbow fitting on the reservoir, while the other end connects to the barbed nipple
of a tee fitting located near the left frame rail on the left side of the front fascia. The other two barbed nipples of the tee fitting are connected to two short
lengths of hose that each terminate at a telescopic headlamp washer nozzle behind the fascia and below the two front lamp units. The hose connections at
the nozzles, at the washer pump and at the washer reservoir elbow are secured using molded plastic quick-connect fittings.
Washer hose or tube 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.
