Just wondering about this topic. My rear washer has stopped working. The pump is fine. Initially it sounded as though it was spraying into the wheelarch. However, The driver's side carpet is soaked and smells of screenwash. Had it to local garage and he was unable to find a way to locate the break. Looks to be behind the dash. He tells me that the dash will have to come out. Is there any access points for the rear washer hose without having to take the whole dash out? Any help would be really appreciated.
