I shit you not you just save me $859. Dealership told me that it needed to be completely replaced, doing the exact same thing that yours was doing. Watch your six minute video, and problem is solved. Thank you so much. I hope you find a 20 or better yet $100 bill in an old pair of jeans sir!

After having the oil changed on my 2015 Tahoe at a local shop, the MyLink screen went blank the same day. I followed this video and boom it WORKS!! Note to self: if someone services your car and checks the cockpit air filter, beware that this plug may get bumped and disconnected. My dealer was ready to put in a $900 part with at least 2 hours of labor.

Dude!! Thank you. I've been dealing with this issue for years in my 2015 Duramax. I just went in there and took that plug out and plugged it back in nice and snug and thr problem is fixed!!

Thanks so much for this suggestion. I tried it Saturday and changed the in-cab A/C filter while I was at it. After removing the lower glove box, I pulled the blue plug and at first, nothing happened. I put the glove box back together thinking it just didn’t work for me. It sat for a day Sunday (didn’t have to go anywhere)- and this morning when I cranked up, it had apparently reset itself and the screen worked fine!! I just had to set the clock/calendar back to auto update. Drove 20 miles to work with no issues. Thanks again for the tip, man! 👍🏻👍🏻

That did it on my Yukon!!! Thank you for sharing, saved a lot of money this way. Good call

This worked for my GMC 2500! The module can be removed and checked. After doing what you described, I reset the radio. It’s been working great since. Thanks for sharing!

Thank you for your video and post. My elderly neighbor has a 2015 Silverado 2500. His GM Intellilink started with the same craziness of changing from Navigation to radio and randomly changing stations. It was like it was possessed! I told him I would Google and see if others have had similar issues. The dealer had told him this was not a common or known issue. Although he was unable to actually get the blue connection off, he said he did push it in further. He has taken the truck out on two different ‘test runs’ over rough roads and his system is no longer possessed. Again thanks for sharing the information for the fix.

I have a 2017 Silverado where the cable connection is different behind the glovebox but using the ideas in this video I unplugged 3 usb type connectors along with two other multi-pin connectors and sprayed them with Circuit Cleaner. Then reassembled and the craziness in the display went away. Thanks for the lead.

Thanks a lot Guy fixed my blank screen after bouncing down a rough road.

Thanks for uploading things like this ur saving people some serious money this repair in the dealer it’s more than 1k

2016 Silverado. My radio channels were changing on their own and screens were changing on their own, very irritating. I pulled the HMI completely out and reset every plug. Its been two weeks and have had no further problems. appreciate your video.

This WORKED! My 2018 Silverado 1500 was constantly changing the station, beeping like a channel had been touched, the maps were always needing re-centered. Showing all stations, switching to all apps, the dash was being changed as well. I can't believe a simple unplug and plug back in fixed it! Per a user below, the bottom glove compartment is all that needs to be removed. 4 screws. SO SIMPLE!!!! Thanks for posting!

So, I have a 2017 Silverado LTZ and I despised that my Radio/Navigation system was acting crazy. My issues were that while listening to the radio it would jump from my radio, to either CD, Bluetooth, Navigation or XM radio. It would do this in a continuous loop. I tried the solution you provided, and thus far appears to work.

Thank you so much for taking the time to do this vid. I put a dab of dielectric grease on my blue cable and it fixed mine. You only need to take the bottom glove box off. Thanks again the black screen was driving me crazy.

Bro, this has been somewhat of an issue since I bought my 2015 Silverado almost a year ago. I just found your video and that worked so far. Thank you !

Thank you for this video probably you save me a lot of money I was gonna take my Chevy suburban to the dealership. And I just fix it thank you very much.

This fix worker to perfection! Thank you!

Thanks for the video... only wish I had seen it before I bought a new display from a junk yard and purchased it :( but yes this worked out like a charm..... it seems to have a bad connection at the box behind the glovebox.... thanks again for sharing the video :)

THANK YOU....so much saved me $160 by Chevy for Diagnostic on my 2017 Chevy Silverado XLT.....scared the crap out of me since I just purchased it in MAY 2020...I got a WIERD computer screen program..thing...and couple hours later the whole thing came back on!! I would put a picture of what happened on here but Don’t know how....LOLOL....thank u

I appreciate you posting this - just got my 2019 Chevy Tahoe straightened out. Thanks, man.

2017 Duramax: The fix worked for me. However with mine I had to unplug the blue connection and pull the fuse. Waited for about 10 minutes, put the fuse back and plugged in the blue wire. The combination of power cycling and pulling the fuse worked for me. Thanks for the video. I'm sure you saved me some money on this one. I truly appreciate it. 👍

got it fixed with this instructions! Thank You Sir!

WORKED FOR ME!!! Thanks... didn't at first but I tried it again and bingo... hope it lasts...

This fixed my issue (2015 Silverado) where the screen was rolling and full of lines like a 1970's black and white tv with a set of rabbit ears. I only had to remove the lower section of the glove box with 4 screws to reach the blue connector. Thanks for the tip!

Thank you VERY much!!! My 2016 GMC Sierra 1500 had a weird issue where the navigation screen would sort of bounce all around, as if somebody were touching all over the screen. Then sometimes it would go blank except for a "no data" message. This fixed it!!!! Thanks again!

thanks for the video it was the same issue on mine. now fixed 👌

I just changed my cabin air filter and my screen did the same thing. Thanks for the video.

Hi, thanks for the video. I tried all that, but what worked for me, was taking the fuse out and polishing the prongs with 400 grit sandpaper and applying a film of graphite lube-viola! Works perfect now.

I just changed my cabin air filter, and the screen went out, saw your video, and mine was the same thing, thanks for posting

That happened to me yesterday and My dashboard even went black I thought my Denali was going to turn off, thank God it didn’t! I’m going to have my husband check I knew it had to be a loose wire lol!

You saved me hundreds of dollars on a radio upgrade. This fixed my issue. Thank you.

Such good info I went to 3 places asking questions and I realized that I knew more about cars than mechanics at the GMC dealership and the auto store I will try it out tomorrow and let you know if it works never had any weird issues just black the whole time I thought it was a fuse.

Worked for me. Thanks so much for the video and the money in my pocket.

I still see everyone is having issues with this. thanks GM. I had this problem back in 2020, 2 weeks after I got a brand new truck. I had to take it to the dealer, and they replaced the entire screen and control module.

Thx for video it worked on my 2016 saved me some $$ . 👍

It worked! Mine went black after changing my cabin filter. Radio and touch buttons worked but no display. My screws were T15. Apparently, I moved the harness away with my fingers to get the cabin filter. Thank you!

2016 GMC Yukon XL- same issue. $1300 later at Devoe Buick GMC in Naples, FL. Has to be a recall. I’m on my Second screen and first HMI module. Going to try and contact GM direct.

After watching this video and reading the blogs below I decided to take the ez way first, I was having real problems with the radio jumping to am, fm, sxm and back. I disconnected the battery as described below , I just came back from a long ride and it worked perfectly. Hopefully it solved the problem! Thanks for the info. ,,

To reset any module in your car, remove battery cables ,neg. first, then pos. Use a jumper wire. Attached to neg first then pos, leave on 5 or so minutes, this drains the capacitors that hold the modules open. And when you reattach the battery wires do neg first then. Pos, leave sit got 10min,,this will reboot the system. Easier than ripping out interior . Also will reset check engine light.

Thank you so much for sharing this info. U was having problems with my stereo and by doing this it got fixed :) you probably saved hundreds of dollars 💸

Great video!! Thank you!

This is amazing, my repair shop said I need a new radio!

2014 GMC SIERRA just stared doing it this is going to be helpful

Did this and it worked. Thanks brother

Just saw your video very interesting , my screen after turning off and on a couple of time it finally just stayed dark .Ill try your fix hope it helps thanks in advance.

This is why I love KZfaq. It has useful shit! And it worked out! Also there is a tab on that terminal in my 2018 gmc sierra. You have to press it and it will pull right out. I didn't kill it. But I sure as hell killed the glitch. Thank you for this video!

Holy smokes thank you so much... I was about to say screw it and replace the whole radio...

Thank you sir I will be trying it at first daylight!

Thanks for this video, exactly the issue, saved me $ and frustration

Thanks for the detailed video. My 2017 Duramax has been doing something similar. I pulled the plug, pulled the 15 amp fuse for 10 minutes, and added some dielectric grease before putting it back together. Worked great on a 60 mile trek, down some rough gravel roads which usually cause it to go crazy. However, one day later it started going crazy again. I pulled it apart again. I added more grease, pulled the fuse, and them put it back together. It was worse - the screen was completely unresponsive. The buttons under the display worked but not the screen. I pulled the glove box out again and noticed the wires to all those connectors appear to be bumping up against the lower glove box compartment (btw you only have to pull the lower compartment out on the 2017 to access the plugs, and the screws are T15 with that model year). I pushed the wires up behind the metal bar that runs behind the upper and lower glove boxes, without pulling the blue wire out of its connection. When I fired it back up everything seemed to work fine. The screen is responsive. I suspect that the wires were rubbing on the bar and putting a strain on the connection. Hopefully this will work, but only time will tell.

Can’t wait to try this for my 16 Tahoe!

Had the same problem and found your video. Sadly the "fix" did not work for me. Once I started moving, the problems started again. On the bright side, I did find out how easy it was to change out my cabin air filter. Thanks for that!

I tried this and it seems to have worked, i just did it and have not drove it yet. My screen would go nuts right on startup. I have a 2018 Silverdo and It would change apps and push random buttons. Huge pain because I use Google maps (I live in Miami and need traffic updates lol) it would act like the screen was being touch a sh@$ton. I calibrated the touch screen as well. If it doesn't work, at least my struck is under warranty. Thanks for the info.

Thanks for your information .it helped me a lot thank you

Going to try this when I get home. Just got quoted $1400+ by Devoe GMC in Naples FL on a 2016 Yukon XL 50K mi! Crazy.

I have a 2015 Chevy Colorado with a similar issue. It seems to be worse when the truck has been sitting in the sun. Anyway removed the plastic silver bezel from around the screen. Behind the bezel are 4 screws that hold the screen assembly in place. Remove the 4 screws. Pull out the screen assembly and disconnect the cables from the back. The screen itself is held in place with several screws that require a star bit. Remove the screws and you will then have access to the LCD screen. There are 3 ribbon cables connected to the screen, remove these and clean the contacts gently on both ends of the cable with a pencil eracer and alcohol. Reassemble and install back in dash. Worked for me.

Thank you!! That's work for me problem solved.

Worked Great ! Thank you !

Very helpful thank you

🙏🏻🙏🏻🙏🏻thank you problem fixed God bless you

It works for my Terrain 2021 Thanks a lot!!!!!

Follow on to my remarks. I discovered that you have to reboot your computer. Just go to 'settings' and search for 'return to factory settings'. So far so good!

My 2018 Silverado K1500 LT just did this. Just bought the vehicle , dealer is going to find the real problem and fix it , FREE OF CHARGE.

Worked like a charm! Thx!!

My 2016 makes phone calls, and puts me on hold, an changes the station, I'm going to try this. Thanks....

Thanks worked for me 👍

Thank-you it does work

Woooo. Thanks man..just tried this myself and low and behold it worked.cheers

I had this problem, I was just at the end of my warranty, (have a friend with the same problem, this is NOT ISOLATED) anyways I Got the dealer to fix it, I was told it's the Touch SCREEN that was bad, so they replaced it. It's worked for about a year or so, now I'm having the same problems. Sad as much as people pay for these Vehicles and Chevy knows there's a problem. I'll give this a try Thanks

I went through the typical troubleshooting process couldn't nail it down, tried the blue plug and its good now thanks so much, by the way if you get the notification that you have a trailer hooked up without the trailer. Squeeze the brake test each time you get the message it will go away, my did.

Ok, I'm wondering where you are finding that upper door (above the glove compartment)?; because my 2014 gmc sle1 awd terrain DOES NOT have that. I'm able to take the glove compartment out with no problem, but that upper dies not exist. When I look under there as best I can, I see where someone did a shabby job of welding a bar across that area. Does that sound like the car may have been wrecked prior to me getting it in 12/2017?

My 2015 high country started doing this I nearly put my fist threw the radio!

Had a similar issue with a 2012 GMC terrain, infotainment center was going in and out, digital speedometer was illuminating bright orange, driver side window was stopping half way up, interior dome lights were shimmering and blinkers would work but no sound. Positive battery cable was completely loose and just needed to be tightened.

The blue wire does control the screen but this is not the issue. I’ve watched dozens and dozens of videos about the blue wire and if you read the comments over 80% of the people in the comments have had the problem reoccur. My personal experience it’s not just the screen going blank but it seems like my entire system reboot itself while I’m driving. I lose all connectivity. The blue wire simply provides video

Thank you so much 🙏🏾🙏🏾🙏🏾

I have a 2018 Silverado. Same problem, it’s driving me crazy! I tried several times to disconnect plug, still no luck. Thanks for info

Thanks my 2016 Chevy Colorado has been having this issue lately. I'll have to try to find this blue connector. (Also in Bakersfield haha nice!)

Believe it’s a T15 instead of T10. If the screws aren’t to tight a T10 will work. I had one that was cross threaded. The T15 got it out.

When this happens does your center lcd gauge go out as well? This is happening to my wifes 2019 denali

We were driving and our screen went totally blank/frozed and showed the backup video mode and this AWFUL LOUD BEEPING sound kept on for 15 minutes then it came back on. Wild

My stereo has only died like this after an exit from the truck, and upon restart. It's never gone out mid use. I'm wondering if it's an issue in the door switch..?

Great video. However I found that just pulling the fuse and reinserting it worked for me. A slightly easier process since you don’t need to remove any screws. Thanks for the help!

2020 Silverado. I bought it two weeks ago. And now this. Unbelievable.

Will that same wire have an effect on the dash it self? Also change the clock and radio station?

Do you tin this will work on my 2013 Buick Encore. My screen has been fine for all of these years and just started about 3 months ago going off when I hit slight bumps in the road and comes bak on. I am not sure the connection will be the same behind my glove box on my Encore? My issue sounds like everyone else's and yours. Thank you so much.

I'm going to give this a try before I spend over $900. at the dealers next week, I've had my 2016 Canyon diagnosed at 2 different shops and both said the module needs to be replaced, I'm not sure what module they are referring to as they didn't explain, possibly the hmi, I get the feeling that being a woman they don't think I would understand, but being from Detroit some of us ladies do know car/truck stuff, lol, thanks for the video.

Dude!!!! Thank you!

Wondering where that connector might be located on a 2016 Buick Verano?

Thank you!!!!!

Hey guys unplugging the negative on the battery worked for me. No need to take off glove box. Try that second. Then third.... Dealership . 😒

Where does the green connector wire run too? I don’t seem too have it on mine I changed blue cable got the screen on but no display at all

Just tried this, 2018 Sierra. No luck. Now it's intermittent while parked also. Worth the simple attempt, must be something else.

Thanks for the great video. I wonder if there is a TSB or recall from G.M. for these failing radios.

Was hoping this would fix My 2017 Tahoe . Unfortunately it didn’t ? I have power to screen but it’s blank . Suggestions?

Gracias me ayudo el video

Any chance this works with a 2012 regal? This kind of problem was happening to me all the time and now display screen will not turn on at all.

what is that piece called were u removed the clip? my truck is missing the whole thing smh

Thanks so much.. it save me $1300.00 and about 2 days waiting time

In a Chevrolet trailblazer 2018 where can I find the cables of the radio ???

All I had to do was disconnect the usb I had in the glove box and it worked fine after that no more black screen
