Windshield Wiper Washer in the rear - did you have the sound of a pump and
just not spray?
William,
Exactly, the pump was ON but nobody was home. The tank had algee growing in
it that clogged up the system. To repair this window washer unit I did the
following:
1) Remove the tank and pump assembly from the van. You'll have to pop off
the interior panel to do this. (The panel clips were re-usable so this was
relatively painless.) The tank is held in with two phillips head screws and
you'll need to unplug the pump electrical and the water hose. The hose was
stuck on the tank, so I cut it off as close to the tank as possible then
used a razor blade to get the hardened hose of the tank nipple.
2) Slide the pump up and out of the tank. It is held in by a rubber
grommet at the tank and compression from the plastic tank.
3) Clean the algee from the tank. I used Simple Green and threw a small rag
inside and shook it real good (rinse and repeat as required).
4) Remove the interior panel from the rear hatch. These clips were not
re-usable, so I had to buy 18 from my local True-Value hardware store @ 49
cents each (9mm). If yours won't pop off, drive a thin bladed putty knife
between the panel and the door to cut them, otherwise you'll break the thin
partical board paneling. With the panel removed you can squeeze the back to
the nozzle/ sprayer thingy and push it out to the exterior. If your hose is
stuck onto the nozzle cut it (again, close as possible to the nozzle so you
won't have to buy more hose & coupler). Clean the nozzle with a pin and
compressed air.
5) Reinstall the tank and fill with water and some Simple Green or bleach
and run the pump from the drivers seat letting the solution run through the
hose and onto the ground or into a bucket until the tank is empty. This
should clear out any loose algee or gunk from the hose.
6) Reinstall the nozzle and fill the tank with windshield washer solution
and you should be good to go.
Note: After putting everything back together mine plugged up again so I
pulled the tank a second time and forced compressed air into the nozzle.
This cleared it up and its been working great ever since.
You can probably can skip the steps of removing the rear hatch panel by
simply blowing compressed air into the nozzle after you disconnect the tank
and clear the gunk that way. But, I would a least clean the tank.
Good luck

washer fluid instead of water.)
