I LOVE YOU MAN. i’m 19 and i got my hummer when i was 14 and i’ve been having this issue so much and decided to take matters into my own hands. super super easy so thank you so much
I appreciate your words! Getting your Hummer at 14 years old is awesome! I'm happy you were able to get your drain issue sorted out. The smell gets so much better inside after it dries out haha
This happened to my rig during a bad storm and shorted out the electrical due to the water being up to the brake pedal. I had towed to a savvy body shop who knew exactly what to do per your video. The damage was over $5000 and luckily my insurance paid it. That was in 2015 and I have only had a slight clog since that I easily cleared out with a long cable. Prior to that it used to overflow all the time into my lap and I had no clue as to why. Thanks for the video, hope it helps other H3 owners.
Good to have you back brother! Your videos have been extremely helpful keeping the old H3 running smooth at 270k. A video on how to find a parasitic battery drain would be extremely helpful. Tried via the usual culprits of damaged trailer harness, and new terminals to no avail. Don't know where to start using a multimeter.
I appreciate your kindness, J! Nice work on keeping your H3 running to 270,000 and beyond. I'm interested in helping troubleshoot your battery drain. Do you have an aftermarket headunit or security system? I had a severe "battery draw" but it ended up being the result of my worn ignition cylinder (what the key slides into). I could pull the key out without the switch fully seating to "off," which kept the accessory power on. Another contributor to my issue was a worn shifter switch (I had to press the shifter all the way forward until it stopped for the computer to recognize the transmission as being in "park"). The combination led to my battery dying due to a constant accessory draw.
@@H3Humper Thanks for the reply ! No aftermarket accessories, everything is stock. I did have an issue not too long with a loose connection in the shifter switch which prevented the key from coming out . How were you able to find the battery draw?
Thanks for the Vid! I did this, and also replaced the gasket around my sunroof glass. I had a full flood, six inches of water in the rig! Never did the back but have not had an issue in two years
Great to hear! Let me know if it stays dry the next time you get some rain. It was such a major comfort upgrade when the swamp smell finally went away in my H3...
The little eyebrow razor shaper thing that Women use on their eyebrows fits and cuts perfectly round hole to remove that cross... Did all 4 of mine mostly by feel and took off only a few pieces under the steering wheel, passenger side just the side panels.... Two in the rear, opened the rear door took a couple screws out of the plastic fender and reached it that way... It's been a couple years so I've forgotten exactly what all I removed but I do remember the rear was way easier than the front, and I've not had one drop of water since, and my H3 is kept outside all the time....
Glad I started skimming the video list I have a leak that’s making the read passenger seatbelt wet. So it’s the rear drain. Also have a failure where my sunroof won’t open I’m assuming the little gear lost some teeth by the clicking noise it’s making
Oh yes, it sounds like you're on the right direction with the rear sunroof drain leak. I wish I had known about the rear drains to make a video for those, as well. My front ones were very clogged and causing leaks up there. Have you unclogged your drains and fixed the gear in your sunroof?
Yoda Hummer Channel - twas able able to access tube via side dash panels and drilled the grommet - found out there was a leak when a torrential rainstorm swamped the interior and rained inside as I was waiting out the storm - fun
Guys, I did such an operation with drainage almost 2 years ago ... it doesn't help - in heavy rain, the drainage can't cope with the flow of water ... all the water flows under the carpet - it never dries! In the end, I sealed the sunroof. Completely dismantled the interior. Carpet dried for a week in the sun. The floor of the car was cleaned of rust and repainted. And I forgot about this problem. Yes, the sunroof won't open now - well, fuck it. I use it as a panoramic roof.
I paid to have my drain cleaned multiple times and it kept getting clogged again quickly. I sealed it with silicone caulking, which didn’t last in the West Texas heat. Now it’s sealed with pro duct tape. Looks like shit, but works.
Dave here, 07 luxury Sport. I am struggling trying to find help with drivers outside door lock, where you put the key in when your fob doesn't work. I bought a new washer and another keyed cylinder mechanism. I took off outside door handle, removed inside door panel. And this is where i cant figure out which way to attack from. Im not familiar with the way the rods come off or how to remove lock from door. Please help. Thx, D
Very quick solution! Unfortunately, the H3 drains have a poor design with very little flow, and they tend to separate when using the compressed air method.
The panel should be similar with an airbag. I have another GM with side curtain airbags in the A-pillar and was able to remove the plastic trim without issue on that one, too. GM doesn't have a good track record with sunroof drains haha.
Easier to fish screen spline down from weep hole in sunroof. Screen spline has a small hole where you attach a straw from can of compressed air. Push the spline through blowing air every so often. Be sure that there is water in sunroof trough which will quickly drain out as you work the spline and air.
I appreciate the tip! I cut the holes in the rubber nipples a bit larger to allow for easier flow of debris out of the bottom. Hoping the issue doesn't return.
My pleasure! and I bet you do... I had it in mine, too. I circulated air under my carpet on hot and dry days to dry it out enough before the smell went away. I actually had a similar issue with my Suburban, and I just decided to completely remove the carpet on my Suburban because I really don't want mold to have anything to grow on. The road noise and heat are higher, but I can tell if there is water anywhere on my floor. I'd like to get a fully rubber floor. Let me know what you decide to do with your H3!
@@H3Humper it'll be in for service tomorrow morning. I don't feel like dealing with this. I'm just gonna let this shop that services it deal with it. I've done enough work on this damn thing. Nice that I have 345k and it's still going
Hey Pete, I've heard compressed air blows the line off the nipple due to the pressure building between the two. This led to some people having their drain tubes drain directly into the cab without them knowing. My method removes those interior tabs on the nipple, so the clogs shouldn't be a future issue. Compressed air is a clever and quick idea, it just might cause further difficulties on our H3's.
Much easier method: I rigged an air blow gun with a hose lead and a nipple that can fit in the front 2 holes (when the sunroof is open). Dont go nuts but blow some air through it. Then visually inspect the grommets to be sure it didnt knock the drain tube out of place. Rear: Pull the fenders off and clean out the grommet. (You cant get to the rear drain holes in the sunroof track)
Thanks for sharing your quick solution! My hope with cutting out the inner portion of the drains is to never have to service them for a clog again. We'll see if it works or not haha.
@@H3Humper they are a 🐓🍭to get to. I don't have that kind of time. Taking out the scuppers in the grommets is prolly better but i dont have to send air often. The carpet was flooded when i bought it. Dealer is a lying punk.
Just picked up a 2006 H3 and noticed the stains on the ceiling as well. I will try the blow out method. I was wondering if you have a video or photos as to how to get to the rear ones?
I plan to replace the 5-cylinder engine with a 6-cylinder, and this will provide me with 50 horse power for my Hummer. What do you think? Would the idea be appropriate or would I face obstacles?
Hello there, having a unique engine swap would be awesome. I have heard the 6-cylinder might be too long to fit. The V8's do fit though, since they're not as long. Let me know what you decide!
The drain plug can be accessed from the underside, meaning the removal of the a-pillar panel isn't necessary. I imagine your panel can still be removed, but there's likely the airbag inside of it.
I cannot believe that one of out State's Attorney's Generals have not taken GM to court and make sure these sorrily designed drains, along with other issues ( like the poor yoke in the transfer case) , , are taken care of FREE. After all. mine began when my Hummer was still under warranty, and continued until my warranty was Expired, then it was my responsibility. That should have been illegal. It was certainly unethical of GM not to be a stand-up manufacturer and cover these. One Dealer had my 2008 Hummer 2 months trying to figure it out ? Really ? Never got it completely resolved.
I have a Hummer 2008 and didnt get to find my rear sun roof drains. i actually broke my sunroof thinking i had rear sunroof drains and use my rails to slide son uncloguing fluid and rusted my rails.
Hello Reco, have you checked the oil pressure sensor? I think those have a tendency to leak. One way I like to find leaks is by cleaning the engine bay and then waiting to see where the oil is dripping from.
@@Dudesaidthat Thank you for your support! When I bought my H3, I couldn't find many repair videos online, so I figured I would try filling some of the void.
I believe I went through the bottom with the glove box removed. I used the side panel to view the plug while reaching in from underneath. I had to use a single pinky to get the nipple back into the firewall. That side is tough. I'm over six foot tall, so I definitely have some pretty long hands and fingers.

Perhaps a door switch. I had an issue with the accessories and head unit not shutting off due to faulty door switch on driver side.
Thanks for the Vid! I did this, and also replaced the gasket around my sunroof glass. I had a full flood, six inches of water in the rig! Never did the back but have not had an issue in two years
Any video of it or pictures?
Awesome video!
I found a swamp on the passenger floor board today.
Thank you sir for the demo mod. 🎉✝️
I just did it! I didn’t have a hot wire saw so I did the best I could with some scissors 😅 thanks for your video. Hoping it works!

Thank you for the video. Helped me figure out how to take the damn trimming off. Found out a line was broken
My pleasure 🙏 A broken line will be nice to have replaced. Water in the cab is quite the annoyance!

Hello John, I'm happy you found the video helpful! Any water issues since you made the change?

I bet the rainstorm swamped your interior in no time! These leaks are no fun at all haha
Great thx thought my front window on my 2006 H3 Hummer tactical edition was why floor was wet.
My pleasure 🙏 Finding the source of water leaks is tough sometimes. Hopefully cleaning your drains resolves the water issue in your H3.

how did you seal the sunroof? I'm about to that point
@@raw7s784, Closed the sunroof and sealed the sunroof edges with polyurethane sealant
I paid to have my drain cleaned multiple times and it kept getting clogged again quickly. I sealed it with silicone caulking, which didn’t last in the West Texas heat. Now it’s sealed with pro duct tape. Looks like shit, but works.
Like to see the back one's

Had this happen on an Infinity I had a while back and air worked great to clear the lines. Just another idea but good work on clearing it out😂
Very quick solution! Unfortunately, the H3 drains have a poor design with very little flow, and they tend to separate when using the compressed air method.
Very helpful ! Thank you !
I appreciate your words, John! Thank you!
so my hummer on the drivers side has my airbag right there on the panel. i do not want to break anything, do you have a solution for that?

Where else do you drive your hummer other then outside 😂😂 0:54
Some of these poor things only get driven around dealership warehouses 😅
i just tore aprt my interior and ran much bigger lines so it would never leak again
Swapping the original lines out for larger ones is a really good idea!
I just welded my roof with a huge metal plate. Dont need it. Now I can sit on my roof and peeee on it😂
