Help rear washer comes on with front one

[blakeypj]

Firstly thanks in advance, the issue I am having is that I put the front washers on to clean the screen and at the same time the rear activates. Anyone any knowledge of what the fault is and how to fix?

Mine does this but only if the car is put into reverse within so long of the front wipers being activated. It's like a courtesy wipe. Do yours come on regardless with the fronts?

I think he means the washer comes on, as well as a wipe.

Hmmm.  I have the problem that my rear wiper is stuck on and it sounds like a dying elephant.
