trailer brakes, a follow up
2018 Montana 3011MS. 2018 GMC 3500 DRW.
I am compelled to post a recent experience. My trailer brakes quit working awhile back. I asked for help in several different forums and several folks gave good solid advice. I replaced the brake hubs but found no axle grease that had blown past the rear seal into the brakes. Several talked about a grounding issue, and they were partially correct. A few days ago I plugged the camper into the trailer plug in the pick up bed and immediately got a message on the dash saying "Check trailer wiring." I took the truck to my local GMC dealer and they told me the plug was no good and was not grounded properly. So they removed the plug in the pick up bed, and I plugged into the original equipment plug on the bumper. And the brakes work now. That was all that was wrong. The auxiliary plug that the dealer added when he installed the 5th wheel in the truck bed was faulty. I do appreciate all the help I got from the other forums, and I learned a lot about the trailer brakes and electrics in the camper and the truck. All is well. (for now anyway)
