Windscreen Washer Systems

When preparing the 4/4 for its MOT, it was found that the driver side windscreen was producing just a mere trickle of water. It was naturally thought to be a blocked nozzle, but not so. The run of the washer tube, from the tee junction to the nozzle, had on original assembly been included in the cable-tie for the under-dash electrical wiring. Consequently, the tight clamping of the cable-tie had progressively compressed the washer tube to the point of almost total restriction.

The warning is therefore, if you have not had cause to use the washers in recent times, don’t wait until the date of the MOT to test the washer system!
