Question
How do I remove the rear window wiper washer fluid resevoir?

Answer
REAR
The rear window washer fluid reservoir is secured to the inside of the lower right liftgate opening pillar in the rear of the passenger compartment. The washer pump and motor unit has a barbed nipple, which is installed through a rubber grommet seal inserted in a hole near the bottom of the reservoir. The washer pump is retained by an interference fit between the barbed nipple and the grommet seal, which is a light press fit.

The washer reservoir has a remote fill cup with a snap-fit filler cap located on the right outer liftgate opening pillar drain channel. A molded rubber filler tube and a vent hose are routed from nipples on the fill cup through a hole in the liftgate opening pillar and are retained to nipples molded into the reservoir by an interference fit. The vent hose allows the reservoir to be completely filled without washer fluid spit-back.

The washer reservoir, the grommet seal, and the fill cup (which includes the filler cap, filler tube and vent hose) are each available for service
