Yesterday, the front washers stopped working, so that I couldn't wash the windscreen when badly needed. Today I had a look at the washer bottle and everything looked to be in order, except that on operating the front washers at the switch....the rear windscreen washers worked. On operating the rear washers at the switch....the rear washers worked.
I took the pump out of the washer bottle and tested it. It works perfectly both ways (it has a reverse flow system so that if you wire it up one way it goes one way and sends water too the front windscreen - if you wire it up the other way it sends water to the rear windscreen). For the time being I have changed the feed tubes around on the washer pump so that I have a supply of water to the front screen when I need it, by using the rear wash function on the switch.
So my conclusion is that there is nothing wrong with the pump, so there must be a short circuit or something somewhere else - either somewhere in the wiring or, more probably, at the windscreen control stalk (although it's anyone's guess why this strange fault should suddenly occur.
So am I correct in my conclusion and does anyone have a spare windscreen wiper / washer arm going spare, or know where I could get one? I am convinced that the car has done this to me because I have just been really nice and spent money on it changing the oil and filters and cleaning the EGR valve etc etc etc. Why do they always bite back and find you something else to do?
