rear wiper leaking

[megatexture]

a mate of mine has a 02-03 gu patrol and when u park up a hill even as low as 4deg faceing up the,rear wiper water outlet leaks to the point it will drain the whole tank out. has any one had this issue could this just be a bad seal on the wiper pump?

There is a little check valve in the line near or in the large barn door. This is your culprit

Yep, spot on.
Ours was doing the same thing, changed the check valve, and all good.
Only problem was at the time (3moths ago) Nissan didn't have any, so had to order in....

After reading this post yesterday I removed mine as it leaked.
Checked , yeah flowed in both directions, given me the sh### for a while now no water.
Hand pump spray bottle with car wash in it, few squirts either way.
Flushed under tap.
Still no good.
Have a bottle of hydrochloric acid.
Dipped a small round file in and applied directly in valve a few drops inside
Giving 1 minute and the valve spring a little work /prodding with file end.
flushed out again with water.
hold valve up hard against running tap with file inserted to work valve internals .
re-flushed with pump bottle car wash squirts and flushed again with clean water.
FIXED, for about 5 cents and 5 minutes
