Troubleshooting Trailer Taillights Where only Running Lights Work
Question:
Trailer lights work fine with my RV and Plymouth Voyager but only the running lights work on my RAV4. Can you please help me with this?

Expert Reply:
Since all of your trailer taillights work with one of your vehicles but not with your 2012 Toyota Rav4 that would indicate that the problem is in the wiring of your Rav4. It could be as simple as corrosion on the trailer plug of your Rav4, or it could be blown fuses or relays of the vehicle.
After cleaning the connectector you will want to do is use a circuit tester like our part # PTW2993 to test the circuits of the 4-way for voltage in all of the correct places when a buddy applies the different taillight functions. See attached video.
