On mine removing Fuse 27 which is for the front wipers or Fuse 15 has no effect on the windshield washer pump. I’m probably misreading the post of @AndySpill Is the windshield washer pump specifically fused?

That is what I am trying to find out my pump doesn’t work front or rear. Wipers work fine…

@kipco

With engine compartment hood open, stand by the engine compartment and have someone
else initiate front windshield wash.. When they do this do you hear the fluid pump in the engine compartment power up and make noise?..... and pump no fluid... If so.....

Good chance your JL's reservoir filter is plugged.... If you hear pump working and no fluid is being moved/dispersed, filter is plugged.

What washer fluid brand do you use?

Is the windshield washer pump fused? I don’t know why I thought I remembered reading it wasn’t?

Tried this already wipers wipe but I hear no pump trying to work and not sure what fluid is in it we just bought it last Friday and it’s been raining like crazy here in Indiana it stopped today so I bought new wipers and put them on and thought to myself I haven’t tried the washer yet and the low washer light has been on so I popped the hood to fill it up and it’s full so now my pump doesn’t work and the low level sensor is bad I’m guessing???

I know this is trivial but I can’t find the answer. @mwilk012 or @alphawolff does the windshield washer pump have a fuse, and if so what fuse number? Anyone?

No fuse, direct power and ground on a reversible driver from the BCM.

Yup looks like its powered right off the BCM on pin 15

Thank you. Searching just showed the fuse question repeatedly unanswered, but I thought I was understanding the wiring diagram to show it was unfused.

That’s what I thought I was seeing. All those numbers, lines and colors on the diagram though

 

[yokramer]

So best bet is pull the liner out get to the pump and see if its getting power, if it is bad pump if its not bad jeep
