Trailer lights don't work?

[tmvikings]

Looking for the best way to fix this issue, my tow lights do not work and they always have. I ran a test on the plug to the driver’s side and all looked well and the tester light worked for power and the blinker. I then went to the passenger side and noticed that the plug had one terminal that did have a little corrosion on it and nothing worked on that side. I followed the ground back to the license plate area and tried to re-ground it nothing. What is the best way to make this work again I want to go fishing! Should I just replace that passenger side plug, I already tried cleaning that side and nothing worked. Thanks for the help.......

I guess I am not clear on what plugs you are talking about? (driver and passenger, there should only be one plug). What type of plug do you have at the vehicle? Just to clarify, none of the lights work on the trailer?

I think he has the little 2 conductor plugs that feed each side and one has gone bad. If you have a soldering gun I would cut out the plugs and put some shrink wrap and solder in a new piece and get rid of the plugs because they are just another source of problems.

yes, that is right I have two plugs and one is bad, the one on the passanger side. these all go to one more plug in between the two that goes right to the trailer plug harness for the boat----HOPE that makes sence. I will take some pic's, I just have to make this work it's driving me mad!!!!!!

Don't think bypassing the plugs would be right but I will if that will work

okay, well can I just bypass the T-connector and solder the wires or do I have to buy a whole new wire harness? Has to be a good easy fix.

I see, You will likely have to by the harness. I have run into issues with the boxes burning out that control the trailer wiring. The reason for the converter box is that likely your vehicle has amber turn signals or turn signals that are separate from the brake light circuit. The controller looks for that signal and directs it appropriately.

Have you checked for power out of the four way connector?
