QX56 TRAILER WIRING (04 MODEL)

[overdalimit]

Help, I have searched all the threads! When I plug my trailer in (Using factory plug) my right hand turn signals and the stop light don't work. It used to work some time ago but now all of the sudden it doesn't. I have checked all of the fuses under the hood and the passenger side dash and everything appears ok. However, one day I pulled my car hauler and the ground came loose, so I don't know if it shorted something out or what. I used a test light to check all of the other terminals in the plug and they work, just not my right hand signals or stop. Also, the rear suspension has stopped working as well, the compressor will not come on at all under load. So, I don't know if these problems are tied into together.

Thanks,
