Jeep grand cherokee windshield wiper fluid not working

with the serious issue of my car not starting out of the way, I want to tackle a much smaller but easily aggravating problem: My windshield washer fluid doesnt Eject.

This has been an issue for over a year, and I cant figure out what the problem is (that said I havent really tried to solve it in the first place lol)

At first, my windshield ejectors stopped spraying, but the rear window wiper still worked with windshield washer fluid

then, after around 6 months, the back stopped working as well.

I checked, and there is still washer fluid inside the bin, and the need washer fluid light isnt on. Checked the fuses next to the battery, none fried. Any idea what might be causing this?

Edit: i dont think its a clog, at least not in the nozzels, cause no fluid appears on the hood, and nothing drips under the car. No liquid appears at all.

Windshield washers not working

My windshield washers are not working front or rear. I know the washer pump/motor is at the bottom of the reservoir. Going to check it to make sure it's bad instead of just replacing it. My question is this, does the rear washer run off of the same one as the front? Or is there a different one I don't know about for the back?

I believe it is two separate motors. I would start with checking the fuses.

I am assuming we are talking about the 2000 XJ mentioned in your "garage" link. There are 2 windshield washer motors stacked vertically at the end of the reservoir, the lower of the two is for the front windshield washers, the higher one is for the rear windshield washer. I just replaced my motors but it appears I also have a clog in the lines or in the front and rear washer nozzles on my 2000. If you haven't pulled the motors yet, you will want a long funnel with a diagonal offset "mouth" if you wish to retain the fluid that is in the reservoir. Also unplug the electrical connectors to the pumps and check voltage to the pump before pulling them, (the upper one will be more difficult) if you have 12V going to the pumps your wiring and fuses are ok.

I think the plug connectors at the motors get a lot of corrosion also.

How do I fix my windshield wiper fluid not coming out?

Clear Clogged Windshield Washer Nozzles Clear the clogged windshield washer nozzle with a pin, then use compressed air to blow the debris backward through the hose. If you hear the pump going but don't get fluid, you probably have clogged windshield washer nozzles.

How do I know if my windshield washer pump is bad?

Symptoms of a Bad or Failing Windshield Washer Pump.

What causes windshield washer pump to stop working?

Dirt in the Nozzles One of the most common causes of screenwash issues is clogged washer nozzles. This happens when small particles of dust and dirt get in the nozzles attached to the top of the bonnet, preventing the spray from working.
