Turns out, now I've had the front of the car in bits, that it was the headlamp washer pump, not the window one. I only know it costs 56 bloody quid because that's how much I paid for one at the local dealer.
One dead foxy equalled £125 worth of new parts required to put the car back to how it looked before our altercation! Had to replace the washer pump, wheel arch liner, bumper grille and the rubbery bit under the chin spoiler.
