Default Windshield Wiper Sprayer

2004 C5

I'm having issues with my driver's side wiper sprayers. The passenger's side "mists" (sprays) correctly, but the driver's side just drains out (seems to be plenty of flow, just no "spray" pattern). I took air and blew through the lines, but it didn't improve. Any ideas?

It's both nozzles on the driver's side wiper arm. Can the nozzles be replaced or do I need to buy the whole wiper arm?

You may also try taking a straight pin or a sewing needle and inserting it into the nozzle opening to see if perhaps there is debris blocking the flow and thereby affecting the spray pattern.

I remember a post some years ago....both nozzles were clogged. The fix was to remove the nozzles and boil for a short period of time. The claim was it fixed the clog. I have no idea if it works.

I have had a nozzle act up where it didn't spay correctly, just squirted to the side, and I was able to clear it with a hot water soak. I am pretty sure it was just crystallized wiper fluid. Also had fluid freeze in a nozzle but I doubt if that's your problem. Good luck.

No luck. I boiled them for a few mins in RO water (so zero minerals). Same result. I'll give vettenut a call.
