I bought a 2005 KJ a few months ago and have one lingering problem. The windshield washer fluid only sprays about 1/3 as high as it should. I replaced all the hoses, swapped the cowling/nozzles with that of my 2004 KJ (which were spraying just fine up until that car's death), blew air through the lines to clear any blockages, and replaced the pump. When none of those worked, I checked the voltage when the pump lever was pulled and got the expected 12V. I'm out of ideas. Any other suggestions before I take it to the dealership to get looked at?
