How are they not working? This is a problem if the trailer has a different set up. Such as the brake and turn signal filament being the same. If that is the problem go to a camper supply store near you and buy and install the convertor box that is made to correct these problems.

The rear brake lights do not work. This includes the center brake light at the top of the rear hatch


although I have not experienced this problem in the exact vehicle you have, General Motors has had problems with the turn signal switches in many of their vehicles. The turn signals may still work properly, but the electric signal from the brake light switch passes through the turn signal switch (also called a combination switch) before it goes to the brake lights. I assume you have no problem shifting out of park or you would have mentioned it, which tells me the brake light switch is functioning properly. First thing to do, as always is to check for blown fuses. If it is a blown fuse, you then need to determine what caused the fuse to blow. If you have towed a trailer recently, it could have been faulty wiring in the trailer, or it could be faulty wiring in the trailer lighting harness of the Escalade.

We have a 2003 f250 super duty. We have no power


Check fuse #6 20amp on your interior fuse panel it may be blown. The relays are located in an auxillary relay box located under the hood on the drivers side fender near the firewall. The system uses 2 relays. One relay turns on for left turn signal, other relay turns on for right signal. Both relays turn on for brake lamps. The fuse #6 is more likely the problem. If the fuse is blown, replace it, wiggle the wiring on the trailer while someone steps on brakes to check for shorts.

I had the same problem on 06 ram, the problem is one of the controll modules under the fuse panel under the hood on the drivers side. My trailer mechanic told me this was a common problem and dodge will only charge about 700 dollars to replace it. he solved my problem by installing a converter on the wires to the tail lights of the truck then running down to the trailer plug. it was most likely caused by a short in the trailer and dodge in their infinate wisdom failed to put a fuse between the trailer and control module. and by the way even though this is a manufacturing defect they will not warranty the module. hope this helps.

No running lights on my trailer.


Turn your headlights on and use a test light to check the harness on your vehicle to make sure you are getting power through the connection. If so, connect the trailer plug into your the trailer receptacle on your vehicle and cut probe through the correct wire after the harness. This will check to ensure you are getting fire through the conection. Always start at your vehicle and work to the trailer. If you are not getting power through the conection, check for a loose wire or replace connector... this is where you will find your problem more than likely. If you're getting power through your harness, you are loosing power between your plug and your lights. Probably a short in the wire. It will be easier to replace the wire instead of trying to locate the short. Good luck!!

2003 denali trailer wiring


If your signals & brakes are on 2 different circuits, ( for example a red lens for stop & an Amber for turn.) then you'll need to buy a converter that goes between vehicle & trailer. They're not too expensive at any trailer or RV place. I think some of the autoparts stores stock them now too.
