My rear windscreen washer has ceased to work and it doesnt appear to be anything obvious. I disconnected the pipe at the rear windscreen motor end and nothing is coming out, so it isnt a blocked jet. There is plenty of fluid in the bottle and the washer motor is working. It would seem the pipe is crushed or kinked somewhere, I was wondering if anybody out there has had a similar problem. It isnt where the tail gate meets the main body of the car because i have checked that. PLEASE HELP as it is driving me potty.
