Rear cargo lights not working

[Toka100]

I can not seem to get the lights in the back of my wagon to turn on when I lift the tail gate. I have searched a few times for this issue and always find the problem seems to be pinched wires. Checked all of them when I installed a back up camera. Bulbs are all good along with fuses. One post talked about a plug being disconnected which I can’t find any unplugged wires.

Is is there something else I am missing. Every other light works except the cargo lights.( taillights turn signals). The front and rear door lights work just fine also.

you need to check sockets if they are able to make contact sometimes one is corroded.
