If I remember correctly, the washer nozzle is inside the cab for the hose connection. Did you try to pull the nozzle off to see if the hose is still connected? It's only held on with two screws on the outside of the Jeep. It will need to come up, and then out and an angle to pull it out. That should tell you if you have a hose off, then have someone hit the washers and see if maybe one of the nozzles are cracked around the bottom. Could be a hose too.... that will be more work. You may even have to remove the heater box to get that far up there!
