How to fix, water getting in to driver and passenger floor on a 99-06 suburban/tahoe/Silverado 

Great thank you Ive got the same issue. I also had a leak coming in by my blower motor or resistor thing and fixed it with caulk I think. So far ok. This is my 4th chevy 2 Suburbans 2 Tahoes I spend more time working on them then driving them . I must have a screw loose

Just found water on both sides thanks to this video, waiting for next rainy day , thanks for the vid

I very much appreciate you going to the trouble to make this video. I had the same problem on my 2001 suburban, I opened up the holes like you did and it stay dry now. Thank you!! PS My grommets looked good but they leaked. I had never done anything to them.

Same problem on the Passenger side. Your video gave me something else to check. The first thing I did was replace my windshield because it was cracked, and I thought maybe it had a bad seal. The next thing I did was reseal the access panel under the cowling which is directly above the Blower motor. Still leaked. SMH So yesterday I removed the RF inner wheel well to see if I could see the drain system, but you can’t it’s inside the part of the fender between the fender and the door jam. When I had the wheel well off I poured water in the center of the cowling to double check the water was draining ok. I also poured water in the sunroof drains and both the left and right drained as they should. By this time I was out of ideas until I saw your video. Thanks I’ll follow up later to let you know if your suggested fix worked. Update. It turned out your cause wasn’t mine, but I did finally discover how the water was getting in. Under the access panel under the cowling is the intake box for the blower fan. I pulled off the cover to the fan under the dash and removed the fan. It’s just a twist on and off and that’s where the water was . I could see it was getting by the cheap ass foam gasket for the intake box. So after I removed the cowling again and the access cover which I sealed up like Fort Knox a few days ago I got access to the box again. The problem is you can’t easily squirt sealant around if you need to put on a finger and apply it that way. I applied a lot then resealed the access cover. If my finger application doesn’t fix the problem I’m going to drill some drain holes where the water always runs to. Have a nice day.

thank you so much for posting this. with all the rain this week down in SA i noticed my truck had a leak. Hopefully tomorrow ill have this issue resolved. thanks !

Thanks bro, had a passenger door floor leak on my 2000 single cab seirra. I thought it was the heater core maybe, but didnt smell anti freeze. Sure enough your video fixed the problem thank you!

Thank you after months of looking for this leak. Thank you for the video.

Thanks man, it helped a lot. I poke a little hole to drain water and then added RTV around the rubber grommet to prevent water from going in.

broooooooooooo im so glad i got to see this i bet this is my exact problem i cant wait to check now. Every one of us, its cus we are audio heads and had to upgrade the sound system lol. i could not for the life of me get that rubber surround back onto that plastic insert, its like you have to be pulling the insert out to be able to get that sleeve onto it but you just cant, idk how they did it that needs its own video lmao. thanks for this bro.

Thank god for more than one person having this problem lol suffering alone sucks and thanks for the video my 05 Sierra has this problem and my cousins 05 Silverado does to should be able to fix after this video

This was the exact problem with mine. Thanks for taking the time to post a video.

Thank you thank you thank you dude. Been struggling with this water forever

Thanks Man, ill try that fix, same w my 2006 Avalanche !

Thankyou very much for posting . This offers more information to the solution

Thanks man super informative having same problem

Thx man has the same issue on the driver side. Im going to give it a try 2mrw.

great video, great explanation and thanks for posting.

Thanks bro hopefully this helps me I have a 1999 Chevy Silverado and it leaks on both sides

I have a 1999 gmc 1500 and the drivers side gets super wet even if I don't drive it when it rains I thought it was coming up from the road hopefully I can see if mines doing the same thing as yours ty for the video. My floor is soaked right now been storming past few days

awesome video. thanks for the help! i have a 2002 silverado and its the same thing. it helped me out!

Worked for me! Thanks

Thanks for the help...... Try to turn your phone 45 degrees so that the whole frame on youtube is used and your video's will look better.

nice video thanks for sharing, how did you get rubber hose( vacume hosing looking thing) on the doors back in place?

thank you this helped a lot!

Thanks, my dude!

nice truck! and good video!

How’d y’all get those panels off?

Thanks for the video. Having the same issue. By poking a hole in there, where does it drain to? Outside the truck or into the rocker? Just don’t want to cause another issue. Thanks

Anyone know what the wires are in the video driver side? Mines soaking wet

Thank you!!

Thank you

Thanks 🙏

me personally I wouldn't drill that hole just another spot for us to develop especially if it is in direct contact with outside I would just replace that rubber grommet you should be able to unhook those wires at one point on its harness inside that door or even before the door to replace it easily I wouldn't want that water in there at all even if it does drain out

There's also a cover under the cowl that has a gasket that fails and allows water to leak into the blower box.

couldn't see hole with the finger in the way...LOL...but what did you use a srewdriver or what? I'm having same issue in my 01...fixed the leak under cowl that caused a short and flooded my blower motor, now driver side is flooded!! I have tools, just don't want to make to big of a hole, don't need bugs getting up and in!!! (Florida)

my eyes might be bad, but i'm having a little trouble seeing the holes you made. how big did you make them and what did you use to make them. i haven't taken my truck apart yet but when i do i'd like to have the tools ready to make the hole. Thank for the video and any info you could pass on.

This just happen to me on my 03 Silverado reg cab only on passenger side I have vinyl floors so takes longer ho get dry can I plz show us or let us know what you use to make the holes thanks

What’s wrong with your speakers I don’t have sound on mine

Theres also a gasket that craps out under these access panels inside the cowl and water leaks behind the dash and down

Hi

Un pedo at 5:20 😂 ...!!!

Instead of drilling holes in your cab, you can order the grommets and boots from Chevy for 20 dollars a piece. These things get old over time and start to leak. You also want your speaker wire running through the inside of that boot.

bro, you completely jacked that grommet when you ran that speaker wire outside of the grommet. There is absolutely no reason why that wire wouldn't fit through the grommet you just ruined it out of ignorance. It leaks because you jacked it up with your hack install.

is gonna rust...
