Hello, I am trying to track down why my rear windshield wiper will not spray fluid out of it. It's a 2000 Cherokee Sport, and the front windshield wiper works fine and sprays well, and the rear one will move fine, just not spray. Any ideas?
Thanks!

 

Do you hear the pump running when you try to use the rear washer? It's likely the pump is bad but it could be the switch, wiring, or a clog or leak.

 

two pumps,back bad?. in tank hidden under driver front fender, pull inner liner, much fun!!

replace both,cheap, wont do it again...

 

rear pump is top one

 

Ok perfect thanks! I do believe it is the pump, so that will be done when I get back home! If anyone else is looking for a good video, Bleepin Jeep has a good one which explains how to take care of it!

 

After checking the pump, check the wiring:


I've had to repair almost every wire in that bundle in the last 2 years. Completely replacing the harness is on my neverending to-do list

 

Gosh I hope it isn't the wiring, that's one thing I really need to work on. I am completely lost when it comes to wiring, but I know eventually I will need to get better at it unless I want to pay a shop to wire in lights

 

My 1999 GC had a split in the rubber hose going to the back. Not enough pressure to make it to the back-glass.
