My windshield wiper fluid isn't squirting out for **** anymore. I have the tank as full as possible and I get a measly squirt that doesn't reach the window at all. I can hear the motor running right by the tank when I do it. Could it be an obstruction in the tubes that go through it? or a dysfunctional pump/motor?
Anything else?

 

are the holes frozen over?

 

I had almost the same problem. I sprayed the hole on the hood with the sprayer gun for washing the car. After that, i filled the thing with soap. Works like new!

 

Your tips/nozzles/squirters/whatever you wanna call them are probably clogged up. I had the same problem. If you have an air compressor, stick the high pressure air where the washer would go (in the tubes); that should clear it up. If not, then blow the other way (from outside in).

 

get a little tiny wire and rod out the washer nozzles,[note the 'aim' before shifting them] if possible warm up the tubing with a lighter and get it off the washer nozzle underhood and put some compressed air thru them.
The 'soap' in the washer fluid can build up/dry out and clog the ports.
Those nozzles are not a lot of money to replace; but I've cleaned out hundreds of them. On my wifes car I soaked the nozzles in 'Joy'dishwashing soap and water overnight, then compressed air to get them to squirt good.
