I have a 2005 Jeep Grand Cherokee, and the windshield wiper fluid doesn't come out on either the front or back window. The washer fluid deposit is full and you can slightly hear the motor. Is there a way you can unclog or fix it?

When the temperature gets below freezing and you use a bargain windshiekd washer fluid or plain water, it freezes and won't work. I normally drain every drop, not just add to what's already in there, and refill with Prestone yellow windshied washer fluid that has a lower freezing point.

your rear wiper motor might be faulty,in the front i would check your fluid level-if it is full and you hear the pump running-check your washer lines to see if they are pinched-usually around where the hood closes

The rear window washer should be utilizing its own switch. Clean out the spray nozzle as well.

When you attempt to use you washers do you 1 hear a noise and no fluid or 2 if no noise no fluid, skip to 3 If 1 check your reservoir fluid level if full check nozzles for wax- polish blocking opening if clean. trace windshield hose to reservoir pull both end loose and Blow air through if clear push back on.
3 Check fuse panel if not marked wiper/washer and you do not have a manual replace all broken fuses your bound to get it that way

Motor is right behind where arm connects to it. You need to remove inner panel.

follow the wires ,there is a short

You have a motor for the front and rear washer. Check the fuses. If the intermitted wipers does not work, there is a relay under the dash near the steering colum that needs to be replaced.

the little pump inside the washer fluid reservoir is bad, replace it

The wipers are supposed to sweep after washer fluid for a while,but if that just started recently then the wiper control module which is part of the delayed wiper

While you were filling the tank you may have disconnected the pump wires. If you can hear the pump activating when you use the switch then the pump may have gotten clogged , check for sediment in the tank.  For the person with the mustang - if its only coming out of one side then its a nozzle clogged or a pinched hose.
