best way to unclog wiper fluid nozzle?

[blizz]

run vinegar through it? poke a tiny needle through it? what say you?

Just did mine.... needle and then paper clip. I should have used vinegar too, can't believe I forgot that. I was too lazy to drive 2 miles to the dealership parts counter, but if the part is a few bucks, I would have just gotten a new one...
