I'm in. My 60s, have had many Fords but this one has me stumped. I fill up the washer fluid tank.. front works fine.. attempt to wash the back window, i hear the pump, no fluid. I pulled the lines under the hood, I have pressure. Blew air from front to back. I see fluid coming out. I attemp several more times to get washer fluid to the rear.. nothing. Then the low washer light comes on and there is no sign of a leak anywhere! No puddle. Where the heck is it going and how?
