OK

Just had this happen

Selected the rear wash wipe by pulling the right hand stalk towards me, and the front washers go off...

This has never happened to me before... I had a "am I right or not?" moment... started doubting myself lmao

I tried it a few times.... each time by pulling the stalk I got both front and rear washers..

I was frozen just before... would back pressure cause this? RRS gone

Common problem on your model i'm affraid Its your stalk that needs replacing the wires have melted together inside the stalk thats what happends when you try to use them when they are frozen, easy fix though replacment stalk £375 + vat.
