Question about Jeep Cars & Trucks
SOURCE: wiper washer
You didn't mention any lost fluids so we can assume that no hapless mechanic has accidentally pulled any tubing loose from the supply.
If, as in many cars, the path of the tubing connecting the washer fluid bottle to the jets on the cowl are visible, carefully pull one the tubes loose and have someone operate the washer to see if the pump is doing anything any more. You may be able to find the 'Y' junction where the tubes split off to feed the two jets.
The rear window washer has its own fluid supply and pump so is completely independent of the front.
If you find the pump working, then you will have to carefully poke a soft, small gauge wire, preferably copper, to try to clean the jets themselves. You probably have some small bits of something clogging the jets and it can help if someone is keeping the washer pump running while you try to clear them as the pressure will aid you.
Worst case, the jets can often be replaced fairly easy and at a cost of a few dollars.

Probably need to replace the pump. Separate pumps for front and rear. Check with a test light to see if there is power to the pump. If it has power but won't work, replace the pump. If no power, you have a wiring issue. Be sure to turn the switch on and have someone push the washer button when you are checking for power. There won't be any until you push it to "wash".

there are two motors ,one runs the front and the other runs the rear. check the connection at the front washer pump sometimes it gets dirty and doesnt make a good connection, if the connection is good and clean then replace the washer pump, here a picture of it. hope this helps

First make sure you have water in washer reservoir, with ignition on reds (not started) then get someone to operate washer while bonnet is closed otherwise the wipers (may come on) may damage your bonnet (would also be a good idea to throw some water on your screen before commencing), listen for a buzzing noise, if you can hear that noise than your washer motor is ok, if not - if fitted with fuse check it and if fuse is ok than your motor needs attention. If motor is ok than while someone is operating the washer motor look under the car to see if there is any water leaking, if there is water leaking than the hose going from your washer bottle to your washer nozzles has come off somewhere, visually check this hose, usually small diameter and clear in colour, reconnect or replace it. If there is no water leak and you have full water and motor is working, than your nozzle, usually located on the bonnet or wiper arms are blocked, this mainly happens after polishing the vehicle. There are 2 main ways of cleaning these nozzles, easiest way is to get a fine pin and poke it several times, this will clean it 85% of the time, if it does not work than you need to find the hose that connects to it and pull apart at a join, closer to the nozzle the better, and give it short burst of compressed air, have to be careful not to pop the hose out at the nozzle as some of them are located in really awkard points, hope this helps.
