Trailer plug issues
Just thought I'd pass this along for other GM owners. First my running lights started acting up and then my electric brakes totally failed on our last trip. Chasing down the problem, I disassembled the 7 wire receptacle to find it full of green ugliness and the brake post completely burned off. Pretty simple to change out the receptacle (Dorman p/n 924-307), the connector from the truck's wiring harness is a little more difficult, I'm still looking for that one. If you haven't already, it would be good idea to check your's, since apparently this is a common problem. RockAuto even has a video how to do it.

To prevent this from happening again, Dieletric Grease. Regular grease will not work. I use the Dialetric grease in EVERY 12v connection from the head lights to tail lights and up to the roof AC's! Takes me about 3 days when we get another coach but well worth the time. And when I say ALL I mean ALL the connections.

Check up under the truck above the spare. Some GMs had another connector tucked away for a 5th wheel plug. It will only have a protective cap on it. If not you can get an aftermarket connector that will have to be spliced into your harness. Just use heat shrink connectors when you splice. I hope the link works that I'm posting. You can purchase it from any RV dealer, I am just familliar with the site that I furnished. The description says it is a Ford replacement but GM uses the same connector. http://store.diamondrv.com/diamond/details.php?ITEM=3211898

It's not expensive. Take your pick of places to buy it. I have a tube I use whenever I find myself dealing with a 12V connection.

I buy it at any auto parts store in a tooth paste size tube for around eight dollars. Some times they call it "tune up grease" for some reason. Permatex is the brand as I recall. I have fixed many refrigerators and water heaters on my RV neighbors RV's. The 12v connections are exposed to the weather and corrode and it does not take much to cause problems.

Hi
Thanks
I didn’t know the auto stores had it. The source I normally purchase from would charge me $110. for the $9 sizes. This is the result of Government requirement for tractability.

No problemo! Exchanging helpful tips is what this forum is for, when we're not fussing about Wally-dockers that is.

Remember, What Is Dielectric Grease? is an insulating grease or non-conductive. If the contacts are not tight the grease forms an insulating film that creates resistance.

I had quite a "conversation" with a counter person at a local NAPA a few weeks ago. He claimed it was conductive and that's the reason ALL the car manufacturers used it!!
Printed out the WIKI definition but haven't bothered to go back with it.
