**trailer brake lights not working**
Just put my camper on to take it for a drive and the brake lights don't work, tried the box trailer to check and those brake lights don't work either. Tried the missus car and the trailer lights worked.
I've unplugged the connections on the car cleaned and replaced and still nothing tested with a multi and it read 13.5 on the breake light pin so I'm at a loss.
If the pin is getting the power and there isn't anything wrong with the trailer what could be going wrong?
Thanks in advance

The plugs not dirty, or lose? Both trailer and car side.
Is it a new plug?? Could be wired wrong.

Did you check the earth pin ? Do the rest of the lights work ? Bit odd if its only the brakes

Plug hasn't been changed on either trailer and it's very clean

Yep all lights work on both trailers except for the brakes but they work when I use a different car so I has to be car side. Just confusing me because it's getting power and it's clean and tight I've redone all connections on the plug and still nothing. I'm about to smash something haha

Since the trailer lights work when connected to the other car, the fault is in your car. It could be a high resistance connection behind the socket, or where the wire taps into the brake light circuit, especially if scotch locks were used. Try a bit of crc or wd40 on the plug and socket, it sometimes works. Also check the resistance between the socket earth pin and the car chassis, it should be close to zero ohms.

Ye not earth pin if the other lights are ok .
Is the brake pin firm in the female end and ring on the male it could be getting pushed away when you plug it up, just try pushing on them... Its going to be something simple and you will kick yourself lol

Has it got those dumb a$$ scotch clips joining the plug to the the harness , they are renowned for failing to make a solid connection
