I have an 02 Ford Focus hatchback. The rear windscreen washer not been working for a while, front washers became temperamental so I've changed the motor which it turns out was faulty. Front washers are working fine now but not rear. I switched the pipes on the motor so I used the front washer switch but water came out of rear washer fine. So it's not blocked, motor and piping is fine. So my only other thought is the switch for the rear washer. Anybody ever had to do this or come across same problem? Any ideas appreciated.
