OK... so a few days back my rear washer stopped working. The pump was still humming when I tried to use it and the reservoir was full. So I tried some basics... I went ahead and pulled the old pump out, drained the fluid tank and then disconnected the rear hose from the wiper.
To verify there wasn't any obstruction, I had my wife stand at the rear hatch and hold her finger over the hole and blew some mild air thru the hose from where it attaches to the motor out the back. There was sufficient air for her to feel it and it sounded smooth. Reconnected with new pump motor and filled the fluid bottle back up... activated the rear pump motor/switch (could hear the new pump running) and after several seconds of priming and trying to get fluid to flow there was nothing.
Pulled the rear inner hatch liner and checked the check-valve w/the little ball 'thingy' and that was clean and functioning fine. I also hooked up my mighty vac to the tubing to check for leaks. Mighty vac held pressure for a couple minutes no problem.
I'm at a loss here... Can't find any leaks, pump is new and running... what else could it be? Any other ideas of what to check?
Appreciate any ideas...
