...chevrolet suburban? well i know where it is but for some reason it doesnt spray the back windshield only the front one. are there two different ones? or is it just clogged?
Sounds like it could be clogged or it could not be hooked up to the wiper or the bottle. if passable start at the wiper in the back and follow the hose to see if it is bent or broken all the way to the tank
