Hyundai i30 cw 2010 - No power supply to the luggage compartment socket of the t

The boot lighter socket does not work. I checked all fuses and everything Ok. In the description of the fuses I have nowhere to say from which fuse it is supplied. Maybe someone knows where the cigarette lighter cable is going from the trunk, where to look for the problem? Lighters in the cabin work.

Rear power socket the same fuse as the front, plug is connected? Maybe someone behind was undressing and not connecting.

It was never undressed. I have a new car. Or rather it was not connected together because there was always tension in the trunk, and only in the cabin after switching the key. In addition, there are separate fuses for both front sockets. The plug on the back is connected. I have already started to disassemble the upholstery to locate where the wires are going. Maybe someone has a diagram.

Maybe it will be helpful that I wanted to connect the hook module power supply to this socket, this module was damaged, maybe it made a short circuit, but all fuses are good. Pictured module.

See what's missing. Masses or plus. Probably, however, the fuse is blown.

There is no plus, I checked the fuses with the bulb by touching both fuse legs, the other bulb cable to ground.
I have a book from Hyundai with a description of all the fuses and there are two, only for sockets in the cockpit. The socket in the trunk had constant voltage, and the two in the cockpit after turning off the key go out. I think something might have fired but where to look at the other end of the wires?

Did you see the fuses under the hood?

Yes, and they are all good, unless somewhere else is hidden.

Do you have the mark "P / OTLET"? It is from the rear socket, if there is good voltage on it and the indicator light is on, it's fault in the installation. Replace with a new fuse, the meter will sometimes show 12v, but under load it will drop.

You were right, there was a fuse in the engine compartment and that's how it behaved, I replaced it and it's ok
