Dude thank you so much for not only showing how to fix the problem but how to fix the stains
Glad it helped! 💪🏼💪🏼
I just put silicone on my back window thinking it was leaking from there ??? Thanks for the video 👍🏽👍🏽👍🏽👍🏽
Just noticed mine doing that on my 2014. The products, tools, & video saved me the headaches on how to remove the staining on the headliners. MUCH THANKS !!!
Glad it helped!!
AJ, saw your video after my 2016 GMC Sierra brake light leaked and stained my headliner. I was like, WTF. After seeing the video and saw it was an easy fix. Lightining Fast worked great! It's always something! Thanks sooooo much for helping people out! Regards!
I am glad the video helped!! It is probably the most frustrating flaw of these trucks. But thankfully an easy fix!
This video saved me from getting rid of my Denali pickup. I couldn’t for the life of me find my leak and it was making mad beyond belief, but this video showed me exactly what the problem was. THANK YOU!
Love to hear this. Glad the video helped!!
man i just noticed mine today . This video helped out .
I think this is my problem right now with my Chev Colorado. Thanks for this video
Glad it helped!
Thank you my friend for that helpfully tip
Great video! Gettin ready to fix my 2016 Sierra....Already happened to my previous truck...2008 Silverado....GM definitely has a problem with these seals going bad! First one was under warranty...this one isn't,...dealer wants 2500 bucks to replace light and headliner. Gonna do it myself for the price of some sealant and cleaner. Will let ya know how it goes!
Fantastic! That makes my brain hurt how much dealers charge. Let me know how it goes!
Thanks. I have the same problem in my 2015 Silverado
I walked outside and wondered why there was condensation IN my truck. I shit a brick when I saw the water damage on the headboard in the back. My Truck is only 7 years old with 100k miles. I baby that thing. Your video definitely helped! I gotta fix this.
Definitely check out the third brake light. If not, my antenna (shark fin) was leaking as well. Factory warranty replaced that though.
thanks for the vid! found my leak a bit too late. now i have to find cleaner for the mold :(
Great video thank you! Not only you showed how to fix the leak you showed how to remove the stain as well. Another approach to this is you can caulk the the gap between the third brake light and the top. My 4.5 year old 2018 hasn’t leaked yet but I did it anyway.
I just had to do this as well. I have an aftermarket LED smoked 3rd brake light. Seal lasted awhile but now started leaking. Put a new seal along with some silicone. Just ordered the stain remover. My stains are very faint, but me knowing they are there if I look closely bothers me haha.
It’s hard to un-see the stains once they start lol
NICE!!! MINES EXACTLY TO THE TEE!!😤😡 I'm on it💪🏽👍🏼✌🏽
I got a 16 1500 Denali n I get the same leak. This video was helpful
Appreciate the feedback!
@@AJLoDato22 anytime
I havent had any leaks.. but had to replace bulb. Removed old seal ordered new one from AMZ.
This was a known issue on my 2005 Colorado too and they issued a recall AFTER my interior had been ruined.
Sheesh 😅
When I originally looked this video up it was for just the replacement for the brake light but then since I changed the brake light since it burnt out now I'm getting water there is another video that has a Amazon new gasket I ordered that and I'm going to put that on and put new silicone sealant on as well
That should do the trick!
Going to fix mine this weekend. My 16 Sierra started this a few months back and it was just when I went through the car wash but now it’s any time water hits it. Super annoying how much we pay for these trucks and simple things like this fail so fast
Agreed, but thankfully it’s not too crazy if a fix. Hopefully it goes away for you!
Do you know off hand if you can see the the roof skin from the 3rd break light Getting PDR done wanted to see if there’s access there instead of taking the roof liner out thanks 🙏
Shoot I don’t remember exactly, but I would say it’ll be good access to the bottom side of the roof metal.
Hey bro! Did you had any problems with your height adjustment from your vland mk6 headlights?
Nope no problems other than I had to tilt the housing back because the adjustment knobs couldn’t give me enough height.
Hey man hope you are well.
Just wondering do you have a update on the Golf Vland headlights? Are they still as good no fogging or drl fading?
Hey man! Unfortunately I did end up selling the car, but the new owner said no complaints thus far. Wish I could be more help.
@@AJLoDato22 Thankyou :))))
How did this fix hold up long term? Just started noticing this same issue with my 2016 2500HD. Bought a new light assembly and the chemical guys lighting stuff to clean the headliner. Hopefully new light assembly shows up before it rains again. Plan on putting a bead of silicone on the new gasket before i install it
It held up about two years until I sold my truck. Worked great, and hope it does for you too!
Just went through this myself. Bought the Chem Guys spray and GE clear silicone.
Its a windy day here so when I sprayed the upholstery cleaner I inhaled more than what actually got on the ceiling.
Also, I put the silicone all the way around the seal. Wasn’t liberal with it but … hopefully I didnt put too much.
Heck yeah, hope it does the trick for you!
Well crap, now my center brake light is out. Did I put too much siicone in there? Is it gonna be hard to get it off again?
I’m pretty sure I plugged it back in sufficiently because the bed dome light still works.
Ceiling looks much better though. 😊
I’m betting I was too rough with the light fixture. There was water inside it so I shook it back and forth. Doh!! 😣🤭
With the silicone, how hard will it be to remove that light to change the bulbs?
I thought the same thing. I have yet to pry it off since then, but I would think it’ll be harder to pull off and will have to be re-sealed when installed again.
This video saved me ALOT of money! However… in the video you showed the truck 3 weeks later after you did the detail. Does it take it that long to properly dry? I did mine yesterday and it looks like it got the stain up but looks like it is leaving g another stain from what I used to clean it? Or maybe it’s still drying? Just curious if that is normal?
I used the same chemical guys stain remover. It got the original stain up but looks like it is leaving another stain from the clean up job if that makes any sense? It literally has only been a day… but it feels dry? What was your experience with yours?
Hmm…mine was dry, I believe in the same day or maybe two. It shouldn’t leave another stain, but I’m not too sure. It might be if you sprayed too much and the chemical is still in the fabric and didn’t wipe off.
Same here. Looks like bigger stain than before now. I applied generously as mentioned in video and wiped excess. Still day one but looking like it’s not doing what it was supposed to
Did you ever figure it would because I’m having the same problem and don’t know how to fix it.
Did you allow the silicone to dry before re mounting the tbl?
I let mine tack up, but not fully dry.
Will any silicone work? I dont want to buy the big tube if I dont have to. Will black silicone work?
I would assume any would work, yes.
I haven’t done this yet. I did replace the light with a brand new GM light but it still leaks I added some extra gaskets around the outside of the light housing and it leaked again. I just watched the video but nervous about silicone in the light before determining the exact cause of the leak. Any thoughts??
Where is it leaking at - the rear? I also had an issue with the shark fin (front antenna) leaking. You could have another leak point. If not, I am an advocate for the silicone because it seals the plastic housing to the metal nicely.
@@AJLoDato22 yes, it is leaking in the back on the headliner just below the third brake light. Just surprised that a brand new light would leak. In fact, I took the first light back and replaced it with another light and still leaking.
@@hipnautic1477 Dang, that is odd. I wish I could offer better advice.
So, you put a new seal and then the silicone?
Just cleaned the seal and then added silicone
My rear center floor against the back (Behind the seat) is pretty wet- Could this also be from the 3rd brake light??
It could be, it wouldn’t hurt to look at the seal on the brake light. I’d also check the rear window or roof rails.
Thanks! I just took the light off and it was full of water! Pretty sure it is the problem- I will know soon :)
@@AJLoDato22
Sup man. My '14 Sierra is leaking now.
Do you think I can just replace it with an aftermarket third brake light to fix this problem?
Yes I believe that would work. As long as it comes with a new gasket it should be good. Or silicone will work too.
@@AJLoDato22 yep. Have silicone on mine now and it’s stopped working completely. Currently looking into some on American trucks to order.
Did you dilute the solution? I bought this and it says to dilute it. But if that’s true it makes no sense why the spray bottle is full.
Hmm that is odd. I did not dilute the spray at all.
Is this the only place it would leak to cause those stains?
I had this spot, and the roof-mounted antenna (aka shark fin). Both leaked, but the dealer replaced the antenna.
Did that cause your headliner to sag or fall?
Nope, thankfully I caught it early enough.
Question: Will the silicone sealant be hard to remove third brake light in future? How to safely remove third brake light in future with this type of sealant? Just pull it?
I would think it would certainly make it harder to pull off later. The only alternative would be installing by a new, better gasket which are available too
Ok I tried it and ZERO leaks! Hell yea thank you. Also update for all this product doesn’t harden enough to make it hard to remove instead it stays soft enough and does the job very well!
You saved me money Good sir!
@@markknights7905 Great news!! Glad the video helped!
u ever comming back to the channel with content?
I actually just thought of sparking it back up 😎. I still have the truck, but debating on which to get - a vette or TDI again for the next build
@@AJLoDato22 I vote Vette 😊
Thanks for sharing… just had this problem in a 2015 Sierra. Total pain!
Isn’t there a seal to replace ?
Yup if you replace the seal, that would be even better.
WHAT ABOUT WHEN YOU NEED TO TO REMOVE IT IN THE FUTURE?
I guess just pull it off, scrape the sealant off and re-do when you have to install it back.
I have the same problem but the water went off to the back driver side down the side onto my carpet. I thought it was the door seals.
Dang that’s terrible. Did fixing the seal work for you?
@@AJLoDato22 I'm on that right now. I'm going to buy the gasket from the link. I'll keep you posted
So it was working for a while but it started to leak again. I think I'm a have to caulk it.
I did this and it still leaked. Now I have to break the light out to replace it. No worries, got a nice one for under 20 bucks.
Hmm thats odd - I hope it does the trick. If not, I’d check the roof rail covers or shark fin antenna
@@AJLoDato22 I was going to ask that, are those black strips covering a seam or is it solid?
@@bogey19018 They cover some clips to attach roof rails to. Though it is really unlikely it's leaking from there (from research I did quick).
My 2015 just started doing this smh
I just found out that I have that problem on my 14.
Dang! Hopefully this video helps get it fixed.
What is a puller?
Just a trim puller tool. I used one instead of a screwdriver so I didn’t chip the taillight.
I've got a 2006 Silverado that had the same problem back in 2018, then the BRAND-NEW 3rd brake-light & seal started leaking just 6-months later!!! Sad to see they still can't fix this simple-issue 12-plus years later, pathetic!!
My 2015 i purchased brand new, leaked so badly it fried the bulb and burned the socket to char, and that plastic they use is high temp, so it got HOT. That means water went into the copper wires as well. Gm has a huge potential for class action lawsuit on this. My interior started to smell musky is when I looked up to see the water stain. Which means mold! GM also has a recall of the curtain airbags because water can corrode them and cause them to go off unexpectedly. How does water get in there GM? Comment here if you want in. Im contacting a lawyer.
Dealership charges 400 for this fix!!
Crazy, right?!
