Well I can hear the sprayer motor whine when I try to release washer fluid nothing comes out so likely a leak somewhere along the line so nothing from the rear wiper
2000 4runner rear defrost and window work just fine no rear wiper or washer .have attempted to normalize the window several times . no luck I assume.my.next step is to check the harness at the wiper motor itself ? My switch is good as all other functions for front wiper and washer work 100%
