My boot unlock works via the remove, but not via the rear switch.

have tried a different switch, but didn't help.

Is it s/w setable? was working, and then suddenly stopped.

 

I think this could be to do with the tailgate wiring.

I had an aftermarket rear camera in and box the coax and power cables were cut.

The rear wiper seems to work intermittently as well.

 

How do you release the wiring so it can be examined repaired?
