The other day i found the rear washer didnt work, even tho the motor was whining away. So i had a look at the tailgate today and found the pipe linking upto the nozzle had been cut somehow, and whenever i pressed the stalk on the steering wheel it was sending washer fluid down the inside of the tailgate and coming out of a small hole at the bottom. whats the best way to replace the actual pipe cos i dont think repairing it wud do much good.
