One day I thought I would push the washer fluid button to clean back window when I noticed no fluid running down and wiper moving like normal and I knew there was fluid in reservoir since I had just filled it so I push the button several more times thinking it would eventually start running down window and to my surprise nothing so I forget about it and go about my day when after shopping I go to put my groceries in the hatch back and find that the carpet was soaked so come to find out all the times I had pushed the rear washer fluid button all the fluid ended up inside the back cargo space soaking the carpet so come to find out the washer fluid hose had either froze over the winter and busted or some thing else had happened to make it leak and the problem has never been fixed and avoid the rear washer button
