Trailer Lights not working, but brand new trailer ?

I cant see why my trailer lights are NOT working when i bought a new trailer with the thing you plug into the XTERRA please help!! i purchased a new 4 pronged thing to for the trailer adapter NEED TO BE FIXED ASAP

Also , all the lights inside my xterra work , but the only thing is the trailer lights? i dont understand

try hooking a meter up to the trailer light connection to make sure you getting power at the connection .

what do you mean meter? like the light thing that tests if theres electricity running through it?

That would be a good start if it lights for DC current.

A multimeter would give more info though.


IE: You are checking to see if electricity is going INTO the harness, FROM the xterra...and if it IS, then you are seeing if its coming OUT of the harness.

If its ALSO coming out of the harness plug for the trailer, you then see if the lights on the trailer are getting juice...and if they are you change the bad light bulb or fix the loose socket, etc.

Maybe these is a problem with the motor. Divert your attention!
