2024 Silverado 1500: integrated 7-blade plug. Trailer brakes lock up instantly upon connection. I have a fleet of trucks and cargo trailers. All have 6-pole connections. All attach and function properly including all electric brakes. My truck locks all brakes. I have two 7-blade to 6-pole adaptors. One center pole hot, one center pole brakes. Both lock brakes without any brake application and 0 gain. All lighting functions properly. All trailers have been inspected and function properly when attached to other fleet tow vehicles. I have tested the 7-blade with each adaptor to verify proper wiring as well as no bleed from hot to another pole. I'm stuck!

Today I was receiving the 'service trailer brake' message my entire 36 mile drive home from work. This message has randomly popped up since I got the truck @ 26,000 miles, now its almost 55,000 and I'd like to fix this issue. Today it was not raining, so I don't think that is the issue. I was not towing when I had the warning. Thanks for any help, Don

So I'm having a weird issue with my 2021 sierra 3500Hd trailer brake controller. The issue: - Hook up trailer #A, when empty brakes needs to be set below 3 to keep tires from locking up. - Hooks up trailer #B, also empty, turn up controller to 10 and I barely feel any braking force from the trailer when manually pushing the slider all the way. I can hear the electric brakes working on the trailer, it's just not giving enough braking force.... so it's not the same issue that others are having where it's not working at all... -No error messages on dash. - both trailers are dual axle and have about the same empty weight. >● If I hook up either trailer to another truck at the yard (Ford or ram are the only other options) the controller needs to be set at 3 or below also to keep tires from locking up. This test rules out any trailer issues! I have searched Google and the forums and could not find any solution! Some people have tried replacing the sliding push control in dash, No luck. Browsed through hundreds and hundreds of forum posts, no solution found......
