I took a trip to Louisiana Sunday night and on the way back I noticed that my cruise control was not working when I stop to get gas I walk to the back of my truck and the brake lights are still on even with the key turned off my immediate thought was that the brake switch was bad After replacing it I found out that it was not the Brake switch  so my second thought was that maybe having recently have pulled a trailer that the trailer pin plug may have been shorted out I disconnected it and that was not the problem either I then began checking fuses all the fuses are good and even when I remove the brake light fuse the brake light still stay on the only way to get them to turn off Is to disconnect the battery I am at a loss of what it could be please help

Do the lights stay on with the key off? Normally the brake switch is the first place to start. As you replaced the switch did the lights turn off when unplugged? How are your brakes, could it be triggered by the pads being warn and needing replaced or a possible ABS issue.

the hot side of the brake circuit is getting 12v, most likely at the trailer plug, check wiring behind and leading the that plug

 They do they even stay on when the fuse is pulled the only way to turn them off is to disconnect the battery the brake pads are good they were replaced about a month ago

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
