Now that my thermostat's been replaced, my cooling system throughly flushed and refilled, something else decided to go on my car. (Big surprise? haha) I noticed this morning that my windshield washer fluid does not spray out of the sprayers. The wipers still go back and forth on the windshield when you pull the switch, but there isn't that distinct sound (which I think is the pump pumping fluid?) that is made when washer fluid is sprayed. What happened? The hoses are all properly connected and the washer fluid reservoir is full, yet no fluid comes through the sprayers?
