So, a while ago, while diagnosing my two bad windshield washers (front was just pinched under the reservoir), I discovered the major trouble I was having in the back. Basically, the rubber in the hose turned to goo and fell apart - every time I sprayed, it was leaking onto my headliner in the very back driver's side of the car. I unplugged the motor so it would stop (although it still leaks every once in a while... dunno how).
It's been dead for a while, and that's fine. However, let's say I wanted to fix this. It seems that the tubing that goes from the car's body to the hatch is mostly bad. How on earth do I replace this tubing so that I can get the sprayer working again?
