So I'm guessing I take the gaiter off and I should see the switch? It's one of those annoying things you put off for ages then try to reverse in a dark spot and it's a pain, new years first job for me I think thanks for the tip
You also might check the loom which leads up inside the trim of the bootlid. It develops breaks as you open and close the boot. I had this problem and sorted it by cutting open the 'bladder' and checking for breaks in the wires themselves. The loom is in the right trim which covers the arm of the bootlid.
