Are your headlights flickering and/or dimming in and out on your Silverado or Sierra? There are a few easy things you can check out to correct this problem. The first thing to take a look at is the ground that runs from the negative side of the battery to the passenger side frame. Take that ground off and clean it real well. If that doesn't work, take your truck to a local parts store (Auto Zone, O' Reilly) to have the battery and alternator tested.
These are a few things that will help you solve your issue. If these don't do it..... best of luck to you - Авто та транспорт
You sir have earned a subscriber! My dash on my 14 silverado has been flickering like crazy and after cleaning that ground (which I wouldn’t have known where the hell it was it if it wasn’t for you) seems to have fixed my problem. Thank you and keep up the great content man 🙌🏼
Ive been scouring the internet looking everywhere trying to get my similar electrical issue figured out on my 2015 6.2L Silverado I cant thank you enough it was the same exact ground on the passenger side undercarriage. Thank you again
Excellent advice. Cleaned small ground no change. Cleaned big ground at alternator, good as new. Thanks young man.
Thanks for the tip about tracing ground wires. In the process, I found a whole bundle of wires that an animal had really gone to town on, and the exposed wires were making contact. Spliced in some extra wire with some wire nuts, and good to go!
Awesome man, bought a Silverado at auction, probably came from the rust belt or bottom of lake. Those grounds are critical came to find out, even caked on mud like you mentioned does a number on your electrical . Thanks for the tips
THANK YOU ,man I have had this problem and it has driven me almost insane. I even took it back to the dealership over this.Thanks to you I will be checking my grounds.Thank again my brother.
Glad to help buddy!
Was it ur issue?
Did you fix it?
Keep up the great work buddy 👍
Life saver my friend got a new subscriber 🤘🏼
Thanks for sharing. Good info. I always enjoy your vids. My buddy and one of your fellow subscribers, Alec Crowder is almost at 1000 subs here on youtube. Take care my fellow Arkansan.
Super helpful! Outstanding sir.
This is for everyone else that this tip didnt work for. In 2016 I inherited a 2006 Chevy Uplander (only produced for a couple yrs.) that had the flickering headlight & dash light problem, primarily only noticed at night. Battery & other parts tested fine, couldnt figure it out. Drove for 5 yrs. like that, finally took it to the dealer & guy behind the desk said the only thing it could be was a bad battery but since I had drivien it for 5 yrs. without any starting issue, I found that hard to believe. In 2021 I looked at the battery date stamp & saw early 2013 so I decided to have it tested again at NTB & local auto mechanic, said it was going bad. Only indication is occasionally I would have to give it 2 tries to start. Given the age, I replaced it and the flickering lights problem was gone. Only been a few months but so far so good. It was an Interstate battery by the way. What I dont understand is, if it was bad 5 yrs ago, how could it start & run in all other ways so good for so long? Anyway, hope my story can help someone else because it was so aggravating & at times dangerous when when other drivers might have thought you were flashing them to get out of the way or semi-trucks thinking you were flashing them to let them in.
Awesome video bro 👍👍👍
Thank you for the info ! I have a 2014 z71 and it just started to do this. I will be doing this before taking it to terry Cullen Chevrolet. Thanks again !
What did you find out about your issue?
@@bradglo1469 they claim they didn’t understood why it was doing it. They even told me if it was something I could just go on about my day. I ended up trading the truck in.
Thank You very much for doing this video!!
Had this same issue on my 2014 Sierra. Along with the flickering headlights, my nav screen and trip screen would flicker and my power steering would go out as well as my parking sensors. Really strange, however, my local dealership had a service bulletin stating that certain trucks in that year range had defective positive battery cables and replacing that should fix those issues. They did that on my truck and haven’t had a single issue for over 3 months now. Just an FYI in case your lights aren’t fixed from cleaning the grounds
This is really good info, I did not know this!
This is exactly my issue will see if Chevy will fix it for me thanks!
@@myaudlife4399 did they fix it for you?
Any suggestions have a 14 silverado passenger side headlight assembly not working at all. If I go over bumps sometimes it will kick on. Checked the ground behind the fender well and cleaned it up. Still having the same issue any suggestions?
Hi I have the same problem with the headlights pulsating only when the engine is running on my 2014 Chevy Silverado ltz ,I'll try your Method to see if
It whether or not
Thanks for posting this video
Thanks, I’ve have with my 2014 Silverado and it’s been bugging me.
I’m gonna give it a shot! My 2015 GMC SLT headlight have a slight flicker. It’s not bad but it’s pissing me off!😂.. I also noticed, if I’m parked, and rev the engine up, my headlights get a little brighter. I hope it’s just a ground! Thanks brotha!
Glad to help! If that doesn’t work check out my video on the g218 ground, it’s another common problem with these trucks and really easy to fix
I have 2013 Chrysler town and country my head light blinking and dashboard I change new battery I change and you alternators what happened you can help me
Good video, thanks!
My lights don’t come on till I use the down part on the windshield wipers, and the wipers don’t work, if I hold it down they stay on but when I release it they go off, taillights headlights and all
I am having the same issue. Volts drop below line. I have gotten a check charging system. Truck has new battery. Cleaned grounds and checked wires. I disconnected ground clamp and there was no change
I’m having the pulsing problem on our 2016 chevy traverse. Except it’s not when I apply the brakes but just going down the road on cruise. And also not applying cruise. It’s when on dim or bright.
Bought 2014 2500 hd notice headlights flicker thought regulator on alt battery alt tested good
Oh damn bro thanks #Dustin for the help
Does anyone have had an issue with y’all dashlights radio and a/c flickering and going crazy???
Hmmm will try tomorrow. I have a feeling is this haven’t watch it in a few months
Hello Dustin I'm having a slight problem on my 2014 chevy siverado 5.3 truck with my headlights pulsing when my blinkers come on any ideas on this?
Great video, thank you for sharing, I have a 2014 gmc sierra an I didn't have any problems but I put an alpharex nova headlights and everything is working fine, but for the first 15 or 20 minutes it starts to be flickering and after that the light is steady, I will really appreciate it if somebody can tell me what is the problem.
I have the same issue with my aftermarket led headlights. Where you able to fix it?
U help me out mine is doing the same thank you
Autozone..Advance Auto..and O'Reilly's can check your battery but not Napa. But this is still a great video
Sir I have Gmc Yukon 2004 6.0 I have same problem and change battery and alternator but still same can I do same and when I remove plug from ground sensor with battery
It’s stop flicking when I put back again start help me
How did you fix your problem?? Was it the ground sensor coming off the battery
Same issue here.. I cleaned the ground on the passenger side and it didn’t work. I had the alternator and battery tested, both are good. Next, I took of the dash to check the two grounds behind the speakers and both looked fine. Other than that I’m stumped!!!! I know there’s other ground throughout the truck but I can’t locate them. I was looking for a book or video that would show the locations of the “grounds” but I haven’t found anything! I Losing my mind now!😤.. it’s pissing me off sooo bad I’m starting to think I should’ve bought a FORD! 🤣
I am in the same boat. Cleaned and checked all the grounds above and still no luck. Maybe start switching out some cables. What a pain in the ass!
I'm having same issue new battery cleaned grounds then new alternator and now idn. Guess I'll get new positive cables
I’m in the same boat. The passenger side ground worked for a little bit now nothing is fixing the issue
@@gmrage Did Yu fix. I need help. This is pissing me off. I have 2008 Silverado
thank you, i wouldnt not recommend to have autozone test your alternator, they will tell you it's bad even though is not true, (happened to us more than once)
My lights on my 2012 Sierra the lights are dimming and can barely see at night
Bad alternator right? ✌️🇺🇸
My 1 month old 2500 duramax batteries died and after I jumped it and charged them with a three hour drive, the only remaining issue is the flickering lights. The dealer said they would need a few days to check it out. I’m a fisherman and I paid 85k for this thing . I don’t have 3 days
I have a 2014 GMC Sierra Denali with 6.2, I have all my lights flickering, service stabilitrack, service trailer brake, parking sensors turning off along with warning of limited assist, power steering intermittently going out and jumpy voltage on gauge, this all happens a few times a day, went to parts store and they said alternator and battery checked out fine but starter failed even though it starts fine! WTF
Have you check the g218 ground, your sounds just like this ground issue. Google g218 ground
did u ever figure out the cause of your problems? i have a 2015 yukon xl that is doing the exact same things that you have described on your truck?
I replaced both abs sensors on my 2017 Sierra and those messages went away and things are back to working order
Steering Assist working now but the message is still showing tho
Nope! Cleaned all the grounds had tge battery and alt checked. Even pulled off the alt and cleand all the mounting points. Worked for one day. Now pulsating again.
My 2008 Silverado 1500 had a flicker problem most evident at night. That's why it was near impossible to get the dealer to find the issue if it only did it at night. Just b4 coming to a stop, I notice a down flicker in my headlights. I thought it was the alternator switching between regular and economy mode? IDK!
My 2011 Silverado does the same
My 08 is doing the same but it'll either switch from one headlight working or both working but one being really dim, I also noticed a lot of flickering when using my brakes, might be a relay going out or wiring issue due to the age but I'm not too sure
Did you figure it out ? Mine flicker on a 2010 going over 65 mph at night ? Also dim sometimes when the a/c kicks on.
Have any of you figured this issue out?? I have 2008 Silverado vortex max just started doing the same exact thing. It's pissing me off
@kenbog3638 That's what mine is. It's a 6.0 Vortex Max.
First thing should always check the battery.
F'N 1ST GODDAMN IT!!! 🆒!!! DUSTIN!!!!
So I cleaned 2 grounds that I found and still the same problem
Might check out my other video on the G218 ground, that has helped some folks out
@@DustinT that is going to be a hassle for me since mine is a 2011 and the dash is already cracked lol
My 2014 high country started doing this. Last week, I floorded it and everything inside flickered once, including the display, etc.
This week while my fat ass was in a drive through, if I would turn the steering wheel, the front lights would almost completely turn off and the power steering would lock up intermittent and steering was impossible.
How did you correct the problem my 2104 is doing the exact same thing..thanks
@@arthurarellano7448 I haven't done it yet since it stopped, but apparently it is the ground in the dash by the speakers where some insulation gets under the bolts when the truck was made. Yt can help with instructions
Damn, i found this video looking for ways to intentionally make my headlight dim and flickering
😂
@Jellyrollfordinner Im gonna have it on a switch so it can look like a street whore whenever I chose
🤡
