Lighting issue

Hey everybody, i'll start off by saying that i'm brand new to the forum and it seems like a great community so far.

I have a 2003 Wrangler Rubicon that is pretty well stock. Never had an issue until a few weeks ago and i'm completely stumped.

So here's the story: I was using a little u-haul trailer to move into my new place (jeep has the mopar tow package from factory). Started to get dark so I turned the lights on and about an hour later I start to smell some burning and notice that all the interior lights (radio, cluster and the rest of the dash lights) start to get more dim as time goes on before they finally go out completely. At this point I get out and inspect further. All the exterior lights are out except for the low beams due to the DRL module. So side markers and tail lights and ambers are out. Blinkers work all the way around as well as the brake lights and also the high beams. I also opened up the trailer and it smelled even more than in the cab of the jeep. This leads me to believe it's a problem with the trailer connection. Took my meter to it today and I get no power at the to the trailer connector, taillights, ambers or side markers.

Any new thoughts into this are helpful as I would like to be able to drive at night again.


Side note: It is a California vehicle and Canadian standards call for daytime running lights. So I installed an aftermarket DRL module (wired properly with secure connections)

Wiring is not my forte hopefully someone else will chime in with more experience. However the only thing I can think of is possibly your wiring harness for your trailer is shorted or grounded out and causing your lights to not work even though there is no more trailer attached. They may be connected together. If your trailer harness is inop your regular lights are also inop. Worth checking but very limited in electrical work.

Id also look at all the Fuses. could have started overheating one which could have caused it to start to melt.... I know they are suppose to just break when overheated but I've seen some nashy stuff in the Fuse box on a car... It never hurts to look.

thanks guys! Yeah, I checked the fuse box and there was nothing out of the ordinary. Also took a look at the connector and it seemed fine. I think what i'll end up doing is finding where the connector ties in and just take it out completely, at least for now.
