My wipers are also packing in on a regular basis: 1st happend last weekend returning from Cornwall in the dark, lashing it down, doing 90.
Tried replacing the fuse, but it seems to be eating them!
Anone any idea what the stock swith is - Robert, do you now know?
Am hoping it isnt related to removing the tow-hitch and choping off the conecting cable that i did at the weekend: i did tape up the free end of the wires well.
