Got my 15 Silverado with the my link system that is staying on after the ignition is off, keys removed and the door has been opened. Got it to time out after about 15 min but the power stayed on with just a black lot screen. The dome lights and instrument cluster turns off so I don't think it's the latch and/or switch. I've had a lot of problems for this truck to only have 4300 miles. Any help is appreciated. Not feeling like I have made the best purchase with this truck.

What do was opened/closed the driver door or one of the other ones? I know on my 14 the only way end the aux radio power is by the drivers door opening... hopefully that helps.

First step is disconnect the battery for 15 minutes then see if it stops. Mines got stuck on once and this fixed it. This has never happened again.

 

The next thing is to look at the door switch and see if it is having an issue. IE open the door and no dome lights.

My 2014 Sierra has done this a few times, but never for that long, maybe 2-3 mins max. I never concerned myself with it.

This has happened to me before. It's always been solved by turning the truck back on and then off again.

 

FWIW, this happens on my wife's Equinox too. My cousin's a GM mechanic and said that they have a software fix for the Equinoxes. Perhaps one will show up for the Silverado soon enough.

Thanks guys. I tried all of the above short of pulling the battery. I could open any door in the truck and it would stay on. Done lights came on when the door opens and dim like normal. It finally went off after about 35 minutes.

 

Truck is at the dealer currently getting services and another round of having the exhaust valve popping issue looked at. Just told them to add this to the list. We'll see what happens.

My '14 Camaro did that.

 

Turned the car off and restarted it. Fixed.

 

Same thing with drivers power window. Wouldn't move. Shut the car off and restart and it was fine. Weird stuff.

Did you ever find out what the problem was?

It is a software bug, basically don't get out from the passenger side and don't leave it on extended times with the engine off and then get out of the vehicle. I've had it happen a few times.

 

 

I can only assume one of the modules goes to sleep after that long and doesn't send the signal to the radio to turn off.

Thanks for the info.

 

 I tried to duplicate what you said.  I turned the ignition on and measured the current at over 2.5 amps.  I turned off the ignition and opened the driver's door.  The radio did turn off but would turn back on if I pressed the radio on/off button.  But, if I pushed the radio on/off button it did turn off and, after a while the current did drop down to 50 millamps or less.  I left the radio fuse in place and the battery still had 12.53v this morning.  I did as you said, and did not open the passenger door.

So, it seems the answer is as you said, but I am not sure if I can trust this problem not to repeat.  I will have to hope I do not go out to a dead battery again.

Did you find any way to permanently correct this problem?

Mine (for my '15) was in the radio's power switch, may have been the software/firmware on the radio, never had it updated before it got totaled. 

 

Did you know that the power switch can be pressed/released to turn the radio on (for 10 minutes) without having the key in the ACC or RUN positions?

From a programmer's perspective ECUs can be woken up from certain events. There was a design decision either at the hardware level or software level that the passenger doors didn't need this event/interrupt. I kind of doubt its a hardware limitation of the ECU which is why I blamed software, and even if it was hardware limited it could be fixed in software by waking up periodically until the radio is actually shut off. GM never accounted that the driver door wouldn't be used (aka start the vehicle and listen to music from passenger side).

 

Of course this is all a guess because I don't actually have access to the code in the ECU.

I have been trying to close the driver's door last and no problem so far.  

 

Thanks for the help.

I have this same issue and took mine to the dealer today.  They diagnosed it as my negative battery cable harness being bad and needs to be replaced.  It is drawing too many mili amps but they said they don’t see any corrosion visible.  Also Battery cable harness isn’t covered under the extended platinum GM warranty. They want to charge 3 hrs labor plus the cable total of about $800!   
Does this sound like an accurate diagnosis and I am pretty sure I could change the cable myself. Has anyone else replaced their battery cables?

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
