I have the same problem. Have a Mazda CX5. I have taken off the nozzles, soaked them in vinegar, then blew them out with compressed air. Working fine. Listened to motor - working fine. Then I started taking the hose apart at different junctions. Ran the windshield washer and the water comes out of the hose in a strong stream. However, there is one small part that is hidden behind the cover that runs all along the dash under the hood. Seems to me there must be a Y or some kind of junction in the hose where it splits the supply of water to run to both nozzles. Somewhere in there must be a clog. Any ideas? I checked into taking that cover off - looks too complicated.
