Short circuit , maybe ????
I have the same problem with my 06 Liberty. I think it has something to do with the trailer towing package as the problem did not occur until I noticed the lights stop working completely on my trailer.
Yes, just like you would anywhere else.
check fuses under the hood
Trailer Lights Work on Other Vehicles but Not MineIF the lights [tail, turn, and brake] are working on your vehicle, AND the trailer lights will work on some other vehicle, that confirms:That the problem is NOT in your vehicle's wiring system.That the problem is either in the trailer wiring, OR is caused by the IMPROPER connection of the connector plug wires to the wiring of your vehicle.It is critical that the connector plugs [on the vehicle and the trailer] are properly connected to the correct wires.The fact that NONE of the lights work when connected to your truck suggests that the defect is related to the GROUND wireas that is the only wire common to all the different light circuits.
Fuse is blown light connector is unplugged ground wire on trailer disconnected
Make sure you have a good ground
The bulbs should be checked on a 1993 Dodge Dakota if the taillights are not working. The plugs on the trailer package should also be checked to make sure that they are working.
Trailer lights are sold at many stores nationwide. You can find trailer lights at home improvement stores. You can also find trailer lights at automobile repair stores.
Not if you can clearly see the lights on the tow vehicle; problem is most cops do not know this and will give you a ticket.
check the connection were the trailer wires are wired in back by the hitch had it happen on a 96 99 01 all the same problem
I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.
Trailer Lights Not Working ProperlyWithout being able to physically see and troubleshoot the defective trailer light wiring system [from the attachment to the vehicle wiring harness (s) all the way to each of the trailer lamps [light bulbs], one can only speculate.I suspect that the cause for part of the lamp filaments working properly while some don't is the result of connecting some wires to the wrong wires.
