I finally got around to fixing my washer nozzles today (the lower ones didn't spray). There'* a slot in the nozzle housing which slips onto a tab on the arm - it'* just this snug fit that holds it there. Like a 1/4" electrical spade connector.
I ran a small needle through the nozzle openings and that did nothing, so I pulled off the pass side lower nozzle and tried to get one of the new Dorman nozzles on there, but first I squirted the washers with the hose off the nozzle - it sprayed like crazy. Hmmm..
The Dorman nozzle was a loose fit on the arm but seemed like it would stay on because the hose kept it from sliding upwards and off the tab.. so I tried the washers - it sprayed ok but it'* direction was off a little, so only half got on the windshield and the rest shot up inside the arm and ran down to the cowl - no good. I took it off and replaced the original. Just for kicks, I squirted the washers again and.. BAM! the original nozzle squirted like it was brand new! How 'bout that!? I guess the nozzle itself wasn't clogged, just some debris in the hose which got flushed out earlier - cool!
So.. I took the hose off the driver'* side and it squirted great. I put the hose back on the original nozzle and now IT works great! Go figure.. Just some gunk in the hoses which got flushed when I tested them off the nozzles.
These Dorman nozzles were only half right - good for upper nozzles only
