Alright guys, so my cruise control has not been working and after some research, I got a lot of answers saying it was due to a bad brake switch. So I went ahead and replaced that and it still wont work. Any other suggestions?

My cruise control stopped working in my 2014 GMC Sierra 1500 5.3L SLT about a month ago. The cruise light comes on in white but wont engage the cruise control. I have looked in the user manual and have not found a reference as to a fuse that i could check. I called a local dealer and they recommended I take it in for diagnostic and pay $75. I would prefer not to if i can avoid it. I have read that this may be caused by a faulty brake switch that needs replacing. Does anyone know of another reason or solution? Where is the brake switch located? I'm new here so any information would help. Thanks..

Hello, Cruise control stopped working (neither normal nor adaptive). When I press the dial to "set" the cruise speed nothing happens, also I read I should be able to change between normal and adaptive cruise by pressing the "cancel cruise" button, but when I do nothing happens. Truck comes from a GM employee who had diagnosed it as the steering wheel being the culprit (in case the switch was defective); he gave me a new steering wheel with the truck which I swapped but it did not work. I guess the easy route would be to take to the dealership for them to diagnose, but since that will take longer and usually several visits: What else should I try? Any specific fuse or something else I should check? thanks! ps. gratuitous pic of a dirty Sierra for your time

I upgraded my factory radio and used the pac rp-5 recommended wiring harness. Factory settings were set and the radio controls on the right side of the steering wheel all work fine. However the left side cruise control doesn't work anymore. Any ideas on how to correct this?

Hey guys, I have a 2017 Silverado High Country and I installed a 6in Fabtech lift with 35in nitto tires back in September 2017 and since then I've been having issues with my cruise control disengaging/turning off at anything above 69mph. When I'm traveling above 69mph, cruise control will turn on and illuminate on the dash, but it wont engage or lock on. Even when I have the cruise set at 65mph and I try to increase the speed to 70mph, it'll immediately cut off/disengage. I took it to the dealership around January 2018 and they told me since the truck has bigger/heavier tires, the computer is reading the wheels going slower than what it reads on the speedometer. They basically said I need to recalibrate the computer to read the new tire size. BUT, a friend of mine also said I could possibly need to re-gear to 4.56 since I'm running heavier tires, which could fix the cruise control cutting off. If anyone has experienced this issue, you help will be greatly appreciated. Thanks guys.

Wondering if it is possible to add adaptive cruise to my 2019 Sierra (it is loaded with all safety features front crash, cross traffic, following distance, etc.) It this just a different module I can install, or is this simply too complex to do? All input is welcome. Thanks!!

My 2004 GMC Sierra cruise control just stopped working. I had no previous issues before this. I checked my cruise switch and brake pedal switch and cruise fuse with a ohm meter and they are okay. I have not changed any brake lights bulbs recently either and all brake lights are working. One strange thing to note is if I am driving down the road and rapidly continue pushing the cruise button the green cruise light will come on then back off rapidly as well. Thanks for any help.

And won't disengage!! 1996 Chevy K1500 Silverado 4x4 pickup with 5.7L vortec cruise won't shut off, truck won't shift into OD and stay. Shut the engine off and recranked it and motor revs like you're flooring it. Anyone know what causes this or how to fix it?

I just bought the thing and the cruise is not working. I’ve changed out the brake pedal switch and checked all the fuses. What else could be causing an issue with the cruise control?

Hey all, I have a 2008 GMC Sierra 2500HD 6.0L Gasoline. Remote start is not working. This sucks a lot for those of us living in Central Alberta Initially the truck didn't start due to a check engine light coming from my downstream O2 sensors. My catalytic converters were cactus, so I removed them, had the O2 sensors adjusted and the engine light disappeared. That was two weeks ago. The remote start worked for one or two days and then I started having issues with it. At first the remote start only worked intermittently, maybe once out of every 10 or so attempts and it was random. Then it stopped working altogether. I press the lock button on the fob and then hit the start button. The park lights on the truck flash as if it's going to engage, and then nothing happens. No sounds either coming from it to suggest it's going to start up. I looked at a few forum posts and dealer recommendations and attempted fixes. This is what I've troubleshooted so far: I start the vehicle manually, then attempt to use remote start. Nothing. I'm aware it only has two start attempts. My lock and unlock buttons both work fine. There are no check engine lights or lights of any kind appearing on the dash. Hood lever sensor seems to be functioning. No hood open warning on dash. (Still may be a problem but I'd like to avoid replacing the latch and sensor unless it's my last option) Oil pressure and coolant temperature are normal. There is no extra key or key fob in the truck. Hazard lights are not on. Vehicle is definitely in park. I replaced the battery in the remote. No dice. I do have a now remote on order just in case although it does seem to be communicating fine with the vehicle. I finally found a blog that suggested that it might be the brake light switch. Apparently this can cause both the cruise control and the remote start to fail if it starts to loose it's marbles. I decided to test out my cruise control and unbeknownst to be me the cruise control will not engage either. So this morning I replaced the brake light switch (which was no easy task). I jumped in my truck to test drive it and it seemed to brake fine and the lights still worked when the pedal was depressed. Cruise control still would not engage (but I don't care as I live in central alberta and don't use it at the moment), but when I returned home, I shut down the vehicle, locked it, and attempted the remote start. It worked!! TWICE!! I was super excited, turned on the ignition to reset it, turned it off, jumped out of the truck and went to attempt it again. Nada. Nothing. No dice. Zippo. I've retried 5 times after turning on the ignition to reset it, and still nothing. Can someone please suggest where to look next? Any ideas? Anyone had the same drama and found a fix? I don't want to take it into a shop, I know it'll cost an arm and a leg! Thanks!

Recently had battery drain drastically on my 2016 1500. Does not want to charge on the battery charger. I can get it to start and, when running, the cruise control doesn't work and the USB ports on the center console don't seem to work; however, the USP port inside the storage area of the console does work. Only thing I had done differently lately is involves messing around with the cruise control, based on reading something in the manual that said that if I held down the cruise control "set" button while in park with the e brake on it would idle at a set RPM. That never happened, but there may be some consistency between doing that and the problems I am having. Any thoughts?
