My windshield washer nozzles are spraying every direction but on the windshield. Any tips for cleaning them out?

It also looks like to replace them, they have to be pulled out from below. Do you have to take the cowl off to get to the washer nozzles? :banghead:

Wow, no one? :(

Stick a straight pin in each hole and aim them at the windshield. Then remove the pins. Rinse. Repeat.
