Hi all, the jeeps decided it doesn't want to spray washer fluid anymore - what's the best way to diagnose the issue here (plus where is the fuse for it), am assuming it's the pump but just thought i'd see if anyone has any ideas first.

Mine was so grungy and looked like the original, I just swapped the whole reservoir out. If you have a hardtop, you'll need the double pump version (if you want the rear window wash to work, that is). It was either Rockauto.com or 1AAuto.com, don't recall, but it was cheap.

While you're at it, you might as well hit up Autozone or OReilly and get some tubing and plastic Ts and replumb the lines. Cheap insurance against future leaks.

Could be as simple as a hose falling off. Have you checked to see if the pump is working or not? Do you have the dual pumps?
 
1. Check the fuse panel behind the glove box. Think it's fuse 13.
2. If fuse is good then pull the wiper pump and bench test. Bench test will verify whether the pump is functional.
