Hummer sunroof drain leak fix problem forever

[@jamesbell6220]

Wow, I have a 2006 H3 which I Love. I purcased it brand new; this leak problem has been the only headach I've experienced since Hummer went out of business. The GM dealer has constantly charged me $300 everytime I needed the tubes cleaned out and they told me that there was no permanent fix. I followed these instructions several weeks ago because my next step would have been to trade the Hummer in for another vehicle. Well this only took me about 1 hour and we have had a lot of heavy rain here in GA, and U haven't had a drop of water come in my H3....Thanks, I'm in Love with my H3 again.

[@fansofthe12hours]

I felt the same way as you did. I have not had one leak since I did this and I live in central florida. It rains everyday from march to october. so I feel you, I love my again too and Im glad I could help

[@tskarzin]

Thanks for the video, could not have done it without you. Drivers side started to leak really badly so I did that and the passenger side before it started. I actually cut some of the plastic that is under the trim piece away to make more room for my hand and better visibility. (passenger side) Worked like a charm. Thanks again.

[@ngcarter78]

Thanks for sharing this, I just had to fix and this worked great on my 2007 H3X. Great job.

[@Banjomute]

Thanks much for this! I did the repair today. Not easy but I got it done. I cheated and used a Dremel tool to cut a playing card size piece of plastic out of the dash right side end cap. That way I could get my hand in there and get it done without as much pain from the plastic edge. I followed the design squares in the plastic and it looks like a factory shape. Anyway it is covered completely by the end trim. I figured I might be in there again sometime so I wanted the better access. It is crazy trying to coax everything around while unseen and upside down. I put personal lubricant on the grommets and fortunately they both slipped back in place pretty directly and the pipes plugged back in OK. Great relief to pour the water (not the whole cup) in the sun roof and actually see it come out onto the pavement instead of inside the car. I was really surprised that, despite only being able to get indirect force on the grommet and pipes, they still popped back into place. Pleasant surprise. Took 3 hours for me. Thanks again.

[@fansofthe12hours]

Banjomute glad to hear. I used my wife’s little hands, I couldn’t even come close to getting my hand in there

Thank you for the video. I will be doing this on the weekend.I have a 2008 H3X and it leaks. I also live in central Florida.

[@UltraKryptonian]

Good info, thanks! My H3 Alpha is leaking in the driver's seat and sometimes on the inside of the front window.

[@kevingrace9774]

Tried this on my nephews 2009 H3. Could not find the grommet. I poured diluted drain cleaner 1:1 with water. Let it sit for 5 mins. Poured water down the drain holes it cleared it right out. Followed that by 30 psi air compressor. Blew out the lines. They work perfect now.

[@m998hmmwv7]

Iv seen people blow the hose off with air. Better off using a vacuum and sucking the dirt out.

This problem cost me over a thousand dollars because the modular on passenger side was shorted out by all the water. Had to replace the circuit board and get it reprogrammed. I will be doing this fix to keep this from happening again. Thanks

[@chucklewis5396]

I ended up putting zip ties on the barb fitting at the top of the A Pillar to make sure they wouldn't come off if I had to use an airline to blow it out.

[@johnrakoczy9277]

I just bought a 2007 H3. Took it to self carwash on 2nd day of owning then discovered the driver's side carpet soaked... I didn't even spray much onto the roof but that has to be where all the water was from :( so.... saw somewhere to use weedeater line and gently unclog. After a while I noticed I could look at head-level to the sunroof and see all the line coiled up inside/around the sunroof so I figure the hose is unhooked up there. Unknown if I did it with the weedeater line, or if this was the original source of the leak. So to fix this, I can remove the left visor and nudge the roofliner down to get to the hose and fitting? Do you think the original leak is elsewhere if the carpet (not the roof) was wet originally, or can a detached drain hose up at the sunroof allow water to flow all the way to the carpet without getting anything else wet? For now... I got a rubber plug for the drain at the sunroof and will hope the other 3 drains will handle the water until I figure out how to fix this. (Bonus was the dealer thought the aftermarket radio was broken but it was a loose wire... it's a top of the line pioneer system with the hidden kicker in back yay!)

[@fansofthe12hours]

Sorry, I just saw this. I have seen in the past where the tube fell out of fire wall behind dash and the water would run out at carpet. Check that.

[@johnrakoczy9277]

@@fansofthe12hours No worries :) UPDATE - well, my garage was taken over by all the construction materials for my bath remodel, so since the H3 was outside I used latex caulk to seal the sunroof... just to be sure. I *also* discovered the tube on the driver side was not attached behind the dash so I re-attached of course after boring the "X" out of the grommet. The other side was fine and someone had already bored out that grommet before. So the sunroof is caulked shut, and the driver side sunroof drain opening has a rubber plug in it, and should any water get past all that... the drain tubes are attached/open at the firewall in front. I pulled out the seats and raised the carpet up, and each day for 7 days I had 2 fans running to dry out the padding front-to-back. Problem solved, right? NOPE. Put everything back together, and we had our first rain in a week... the driver side carpet was SOAKED... I am pissed. I noticed the airbag nylon in the a-pillar is wet. There is no wetness anywhere on the ceiling, or evidence of any water stains. WHERE the hell is the water coming from??? I even poured water all over the roof and into every slot/groove I could find in the top left quarter of the roof and never saw anything coming inside. I love this ride, it's my first Hummer... but I'm so disappointed... any thoughts on where the water is coming from? Windshield? Outer plastic trim on a-pillar? I'm at a complete loss :( My dealership wants $100 to "troubleshoot" the issue but I don't see what they are going to do that I couldn't do myself.

its a good fix however they are very hard to get to from under the dash, but if you are in need of a windshield replacement when the glass guy removes the windshield they are just under the windshield and with a long pair of needle nose pliers you can easily get to them.

[@fansofthe12hours]

Stephen Eavenson thx great advice.

[@walirahim9855]

Best to reroute that hose to the floor. Autozone, I think it's 3/8ths inch. I used gas line hose.

[@L2FlyMN]

Yep, hit the brakes & get soaked! 😖 Sometimes you just want to backhand an engineer!!! 🤪

[@L2FlyMN]

I permanently fixed the issue, and made a recording for KZbin on how I did it, titled The 2006 H-3 Hummer, & how I permanently fixed the sunroof drainage issue. You can hear it in my voice that I was quite pissed, because of what I had to go through, all because of poor engineering to start with!

[@LoserJJA79]

Thanks for the video. i have a question. My H3 is leaking in front also but sunroof won't open anymore and apparently can't be opened manually. Is there a way to get to top of drain tubes with sunroof closed and top liner removed?

[@fansofthe12hours]

Unfortunately I do not know but I recommend removing the fire wall grommets and drilling them. That might prevent you from having to get up in the sunroof area.

[@m998hmmwv7]

Yes do that.. Go in through the roof liner.

Since the grommets pass through the firewall, can they be accessed from under the hood?

Very difficult.

Yes, to shorten the video. The beam covers come off the same if I remember correctly. Was you able to get your hummer fixed?

[@mikep4823]

My fix for this was a clear caulking all around the sunroof and took the fuse out. Its a 10yr old truck and i hate the sun shinning on my bald head and never opened the damn thing anyways. Now that i know the fix if i ever sell it il rip that caulking out and clear those tubes but for now the hell with it. When it started to leak i started to laugh because i hate it when any manufacture puts a hole in any roof whatsoever. Other then that i like the truck 2008 Alpha 5.3 with over 170000 miles on it. All around a great truck.

Hello this has been a nightmare for me. I am not able to see the grommet. I live in Central Florida. Are you interesting in getting paid to fix it, I rather have someone with experience fix it than take it to the dealer because they call a 3rd party water guy.....Please let me know.

Doesn't GM care about their customers 2006 Hummer H3 ignition problem key getting stuck in ignition when turned off why is there recall

[@RandyXB9R]

There is a tiny wire under the console that surrounds your shift lever. There is a video on KZbin about this. Over time, that tiny wire which is a transmission interlock device with the ignition switch, not allowing the key to turn, will become either loose or broken. If you are in a quiet place, pop that cover loose and from the passenger seat, examine it. It's toward the back somewhat under the coin tray, between there and the shifter... So with the key in, wiggle that wire and listen for a tiny "clink" sound. Your key will pull out with ease. Naturally I left the cover open for 8 months, touching the wire when I might have the problem until one day came when it no longer worked. I drove home, pulled the cover off completely and actually soldered in a longer piece of wire, routed it properly and never had the issue again. KZbin videos can be terribly wrong (the 5 that I watched before seeing the one about the loose wire) or they can be golden. Watch a bunch of them before tinkering. Some of the other "cures" for that key issue ranged from beating the switch with a rubber hammer (honestly?) to full disassembly of the steering column/replace ignition switch/etc. All it was... simple tiny wire fix... Hope this helps!
