I was driving with my kids in 2018 Silverado completely stock, no modifications at all and suddenly...lost power for about 45 secs... Pulled off as best as i could... Got the alert "theft detection" and to cycle driver side window up and down.. restarted the truck and the turn signals were sending a fault and flashing faster than normal... I was thinking the worst ... Checked all fuses and relays.. wondering what in the world is going on.. then o found your video and tried it.. they were full of corrosion and dirt.. electrical cleaning spray and dielectric grease .. no more issues... You saved me a ton of $ and time .... Thank you ao much... Very grateful to you for making this video.... I find it crazy that one electrical plug related to turn signals can shut the entire vehicle... I think Im gonna be switching to something more "old school" maybe a 80's bronco or something i can actually work on

Make new video

Hey thanks so much for your video, my 2009 Chevy was having the same issues! You saved me a trip to the parts store for new bulbs!!! You helped me fix the problem👍🏽

Hi my GMC Acadia having the same issue..i just wondering if it is same problem as well?

I have a 2014 and i dont see the connectors on the bottom rear where yours is located...

Thank you

Hoping this comment gets noticed. I have a 2010 Silverado 1500. Brand new head lights and tail lights. Wired correctly with load resistors. Checked all the fuses as well. But god forbid if I turn that switch to the right or left it keeps hyper flashing. Do you recommend checking those back connections at the junction box still as a potential fix?

Dude thank you! Mine were nasty! Used some wd40 contact cleaner

Saved me a ton of money bud! Thank you!

THANK YOU JIMMY 💯💪🏽🙏🏼!!! Simple fix saving $500.00. YOUR AWESOME 🤙🏼

Nice, 👍🏼

Also you might want to check to make sure your blinker is not burned out

Yes sir, first place I looked but haven't done it yet, thanks for the video

Thank you.

This really helped me out haha 2023. 2012 gmc serria 1500 sle

Thanks

Having a similar situation with my 02 Silverado. Do you think that would be the same set up and what did you use to clean the terminal ?

Just ran across this video!!! Thanks so much for posting. I did what you recommended to my 2012 Silverado, and it fixed the same issue you had. Can’t believe it!!! I was thinking BCM the whole time.

wow tnx

Hey dude! Thanks for the video! It worked! Everything is fine now! Thanks

Thank you for your toubleshooting expertise. These corrosion problems are difficult to find!

Thank you, same truck same problem. You saved me a lot of time looking

does it hurt?

Thank you, I have the same problem.

Thank You!!

Thank you. I first tested my hazard lights (they work fine) but no turn signal. I'll unplug and look for corrosion as suggested.

Got to love KZfaq. Glad I found this. My 09 GMC Sierra did the fast blinking with nothing happening at the left rear. This was after a fuel pump replacement. Found that connector after watching this video and found it wasn't fully seated. Had to clean the dirt and corrosion around the plug so it would seat completely and my signal works again. I need to get rid of this old crusty truck lol.

I have tried everything except that I will try in the morning and Let you know

what about independently

Short and sweet, something for me to check! Also some Chevy trucks of 2000's era have a history of burning out the flasher relay found under the dash panel below the steering column, to possibly help future viewers.

What was the numbers of your tail light bulbs I come up with someone had missed matched bulbs numbers 3157 and 3156 I guess once it’s a little hotter bolt Thank you for your advice you helped me a lot

What did you use to clean them?

Worked for my 2011 Sierra 1500. Thank you!

Hey Jimmy I have a problem in my truck whit signal Ligths in one side do you think is going to the same problem??

2008 Chevy Silverado. My blinkers work but I have no response sound when I use them. Also, front speakers don't work but my rear speakers do. Any advice?

I have this problem but only with the left side not even my running lights turn on just the reverse light and my reverse light blinks instead of the turn signals my break light dont work on the left either

I told my dad he won't listen to me and is being a jerk about it saying its not it ik it is it

Cleaned those up didn't look corroded and that was the fix. Took the trailer plug out and cleaned all the dirt out of the plug. 2008 GMC 2500 HD Sierra SLE.

Thank you so much for this video. Right turn signal/BrakeLight/Reverse Light not working. Spent a lot of time researching what could be my problem. This video fixed my problem in 2 minutes. I have a 2010 GMC 2500.

Thank you lots from the 49th state! Much love and thank for the much needed advice.

I referenced your video to check my 2011 Sierra 1500 this morning. My driver's side signals don't respond in any way but the hazards do so I was thinking this had an outside chance of being the source of the issue. Still I really appreciated the video and it got me looking at a part of the truck I wasn't aware of. Last week I changed out the rear differential oil so I got to see how dirty and rusty the area was (the top of the spare which may have never been dropped before this was totally filthy). I was actually surprised to see how clean the insides of the four plug connectors in the area were. I'm going to look more around the Body Control Module (BCM) wiring and possibly the BCM itself. Thank you Jimikiwi!!!

Can you please move to Minnesota

That was it!? Mine didn't even look corroded, but I unplugged it and plugged it back in, works. Go figure.

NICE! Just what I needed...and it worked!

Thanks, man, this was just what I needed. My '08 Silverado started flashing fast, but all the elements were still lighting up. Popping the leftmost (driver side) blue connector was the one that I think did it. I did them all, off and back on, didn't notice any dirt or corrosion, but the contact must be improved anyway, 'cause now I've got normal blink speeds! Very helpful and well done.

Thank you for this--im gonna go check my '14 chevy silverado. After a heavy snow, I used a set of chains that whipped the ever-loving daylight out of the wheel well (speed increased without pullout for removal). Next time I started my truck up, I had the issue with my rear passenger turn signal not working, and haven't been able to track down why. Based on location and what happened, I'll check this next.

Please help: 08 Silverado 1500 When I turn on the truck the driver side tail light it out and when I have it in park and or put my turn signal the reverse lights turn on I unlock the truck and the driver side won’t turn on but when I lock it they do turn on

How did you resolve the corrosion any recommendations for products thanks

Just bought a 2014 and I have the same problem......... Thanks for the video I will try your suggestion and repost my results Thanks for the video 😎👍👍
