My wiper fluid isn't coming out. Yes, I filled it! Is there a fuse for this that could be blown for the pump? The wipers do move when I turn them on. There is no ice blocking the holes for the fluid.
Can you hear the pump when you activate the wipers?
Are you sure the line is not blocked or the pick up has something restricting the fluid? Since both the front and back are not working, it may be the pump, or electrical connection. Make sure you have electrical power to the pump, the switch is working, and if the pump engages when it is turned on. You will need a helper to activate the wipers while someone can check the pump if it is working. Disconnect the hose at the start of the pump and see if fluid comes out. If it does your in luck. It is more that likely a blocked hose somewhere or a hole in it and the fluid is cleaning something else.
Mine was doing the same. My motor was going but nothing came out. I poured vinegar into the reservoir and ran it. After continuously running the system front and back for 30 minutes, it started coming out. The acid in the vinegar will clear the lines without destroying the rubber. I also removed the nozzles and soaked them in a vinegar/water solution 1:1 for 30 minutes. Now it all works great!!!
