New...so I hope I'm not repeating something...

My driver's side windshield wiper fluid valve won't squirt water. I checked all the hoses and they look intact. I used a needle to try to unclog it, but nothing. Any advice on how to fix this?

disconnect it at the pump and put low pressure air into it, and see where it is blocked inside one of the hoses,

Welcome to this forum! Stick the tube from a can of WD-40 into the hose, and spray it out. I did this one time, and it worked.
