Brake light issue
I have a 2002 4.7 L Durango with a factory tow package and a Reese Controller. Camping this weekend I noticed that the trailer brake lights would not come on... weird. It was just a short trip and anxious to get out to the lake, we made the trip. All other lights worked fine. Got to camp later that day I tried fiddling with the lights and noticed that none of the D's brake lights light up including the top. But if I manually activate the trailer brakes using the switch I get lights both in the D and on the trailer. Thinking it is the stop switch at the pedal I pull it out and ohm test it according to the service manual and it checks out. The FSM mentions that the Combination Flasher has a Brake Light Output in the relay so I replace it... Presto, I now have lower Brake Lights on the D, but they won't turn off. Still no top light, still no trailer brake lights, or power at the plug, and my Trailer Brake Controller is active, locking the trailer brakes.
Any thoughts, I put the old Combination Flasher back in to get home and manually actuated the trailer brakes to get lights when I needed them and all the other lights work normally.
