The PHP hole is visible from the rear bumper with a flashlight - look forward to where the rear wheels are, and to the cross member in the middle of the car that supports the wheels.
You shouldn't have to remove anything in the back of the trunk to check the plugs, I don''t think. I'm not sure that they will show you any problem though, to be honest. Just something to check.
Have you tried running your controls rapidly around to clean the contacts?
