Trailer Lights On 2004 Heritage Trailer Not Functioning

Question:

my right turn signal and brake lights work but nothing else on my trailer light. When I check the connector from the truck the green wire for the right side is the only one with power, is the a fuse or relay problem and where can I find the fuses that need to be checked.

The first thing you will want to do is check the wires that are leading into the connector on the vehicle side of the connector. If you are getting current going into the connector but none coming out, the connector is bad and needs to be replaced. I recommend using a circuit tester like part # PTW2992.

You said the right turn signal and brake lights were the only thing working. Are the brake lights working on both sides of the trailer? If so, then you will want to check the wiring connections and ground wire. If the system was working at one point and stopped working, then a wire may have become damaged or loose or corrosion has caused the problem.

If you wish to check the fuses on your vehicle you need to check your owner's manual or with your dealership to see where you can locate the fuses for your turn signals.

If everything checks out on the vehicle side, the problem will be on the trailer. You will need to check the wires and ground wire for each of the lights that are not working. Look for breaks in the wires or signs of damage and repair any you may find.
