Wiper switch
Agreed, the switches are suspect. Easily removed, the screws that hold it to the column are kind of accessible by removing the upper and lower cowling. You'll need a small torq screwdriver/socket. I can now change in 10 mins! However, don't get a switch from the USA, it won't work well it will but it works different things so general confusion. There is also more than one UK variant, so I discovered with a secondhand one. The replacement I had would not work properly until it was reunited with its own GEM module from the same scrap vehicle. Do not be tempted to try and dismantle the switch to repair unless you are more nimble fingered than me. Bits fly everywhere! If I knew what I knew now, I would have ordered it by chassis number from ford
