manual switch under black rubber? Switch is integrated into black plastic moulding (which Ford call the handle - the entire black moulding) on tailgate. Switch filled with water and stopped working. Have removed plastic panel inside tailgate and can see 4 nuts, however, there are also 2 white plastic plugs - one at each end. Do these white plastic plugs pull off or are they snapped off. If snapped off then do I need to replace this black plastic moulding too. Any advice appreciated. Thanks in advance.
