Re: windshield wsher problems
Fuse 29 (10A) on the junction block under the steering wheel is used for the washer pump. Check that one first.
Its for the front and the rear washer pump, so if the rear still works, you know the fuse is fine.
If you want to access the pump, you have indeed to remove the lh fender liner, and maybe even have to jack the jeep to get enough room to access the pump.
