Windshield Wiper Fluid barely coming out....WTF?

I believe I found a fix for the poor washer fluid sprayers. Basically, I soaked the nozzles in a vinegar water solution and hit them with compressed air.

First, I confirmed that the pump was actually working by sound. Next I disconnected the hose going into the driver side nozzle and ran the pump to verify fluid was making it to the nozzle. Since water was getting there with good pressure, the problem was the nozzle. There is a check valve in the nozzle so flow will only go one way. I tried blowing water through the nozzle and felt a lot of resistance. Either the check valve was sticking or the nozzle office was clogged. I soaked the nozzle in vinegar/water in case there was any build up. This didn't solve the issue, but may have helped loosen things up. I then ran compressed air through the system. The trick was blowing air in reverse. (i.e. in through the sprayer) blowing air into the water inlet, didn't seem to help. This leads me to believe whatever was clogging mine was too large to push through the sprayer orface.
