Hello all, just spreading some knowledge. When I bought the vehicle the rear was not working. After extensive googling and looking at manuals, I was getting no where. Bottle full of water, pump making a noise, jets not blocked, but still no spray. So I decided to rip apart the car. Found culprit. In the boot under carpet there is a plastic straight connector. The tube had come off and filled boot with water. Looms and carpet all green, rust beginning in floor pan, no explains why there was a strange smell in car. Problem solved. Now have to work out how to kill the smell ??????
