For some strange reason my rear wash/wipe switch has decided to start working the front washers instead of the rear one. Is it likely to be an electrical fault or may it be something else(wondered if it diverts water to the front ones if the rear washer pipe becomes blocked???) Not what i need when the weather is starting to get crappy.

May be a stuck valve in the pump? Same pump for front and rear washers, just reverses direction and pushes a shuttle valve across to expose the correct outlet normally. Can sometimes be sorted but may be best to fit a new pump.

yep buggered diverter valve in the pump. Cheaper to get one from peugeot than ren though lol
