This is a common problem on most of the small hatchback Ford models.The earth circuit for the tailgate is taken thro the hingepins of the tailgate .After a few years the pins build up corrosion and the earth is lost.The best solution is to run an additional earth wire from one of the hinge bolts(usually a 10mm head size)to an earth point inside the boot area,following the line of the boot rubber seal.hth
