Hello I have a 2012 dodge journey sxt with a v6. the driver side tail light doesn't work. When the engine is running if I turn on the lights after about 7 seconds the drivers side tail lights will flash twice then go out then flash twice once more then they won't come on again. The other side woks normally. I don't know if this is some sort of a code telling me what IS wrong. I had installed a curt trailer wiring harness when I got the vehicle 4 years ago and it has worked ok till now. I checked all the wiring on the trailer wiring harness and everything seems ok. I disconnected the negative battery terminal to reset the computer?? This didn't change anything. Any help would be appreciated
