ever since we got hit with the snow storm up here, my windshield washer nozzles have been acting up. one will work fine, but another won't "fire" as good, and another won't "fire" at all (the fluid just leaks out of the nozzle). i tried to clean the nozzles gently with a safety pin, but it still persists. anyone else have this problem? is it just frost in the tubes? spooky...

 

take out the nozzle, let them soak in a mixture of warm water and vinegar. that solved my problems. it was just some calcium deposits inside the nozzle.

 

Buy new nozzles. Usually a few bucks each.
