Angry window washer no pressure?

Well itís been a good while now; my window washer nozzles have absolutely no or very little pressure. It doesnít even reach the windshield? Nothing is clogged I donít think, I used needles and tried cleaning the nozzles but no go. But every now and then when Iím stopped its spray perfectly? But on highway or driving at 40mph it doesnít work. Is my pump done? What do I have to replace? Thanks! Ps: I drive a 2002 wrx

You might check for a pinched hose, other then the motor being shot, thats the only thing i can think of...can you hear the motor going when your not getting any fluid.

If you simply pushed a needle into the nozzle, you may have just pushed the blockage back into the chamber behind the nozzle. After a while, the blockage can gmake it's way back to the jet. That's the only way I can think of the problem coming and going.
The way to clean this is to disconnect the washer pipe from the jet and wash it out backwards. ie, force water down through the jet.
Good luck.

Could also be that you're getting air into the line due to a hole in one of the hoses or a wrong size hose. At one point I changed the washer fluid hoses out for some silicone ones. After a while I had no pressure, it was because the new hose was a bit too big and not sealing on the nipples of the washer nozzles.

I had the same problem and found check-valves sticking. There is a valve under the hood in each of the water lines. I removed the valve and all was well. The plastic valves had a small notch wore in the seat that was causing the problem. I replaced the valve with a plastic barbed connector from AutoParts.The valve was there to prevent the washer solution from draining back out of the tubing. Leaving the valves out requires about an additional 1-2 seconds for the tubing to reprime before water hits the windshield which to me was no problem. Try it. Ed

The down side is that the wipers sweep for those couple of seconds on an almost dry dirty (gritty) screen before water gets there. This can wear the blades and scratch the screen.
It does have the advantage that there is no water left in the jets to freeze in the winter.
Your choice.

I had the same problem also with the check valves. Found that the valves were clogged with some gummy deposit (turned out that the wiper fluid that I had been using wasn't compatible with what the non-dealership shop used at the last service; the resulting mixture threw a precipitate that gummed up the check valves). Ultimately, I had to drain the wiper fluid reservoir, and replace the check valves (they were a few bucks for a pair).
