Default OT: Wetrug in my Suburban

Greetings -

The carpet in the back of my Suburban has been getting wet and I can't figure out where the water is coming from. It's getting wet enough that the rug is full of mold and mildew. The truck is only used these days when I'm going back and forth to the marina, and that's not all that often. I would have assumed that the water may be splashing up from the underside, but since the truck sits still most of the time, this can't be the case. I have opened up the rear glass hatch during a rain storm to see if there was water coming in this way, but I didn't see any water pooling around the door or on the edge of the rug by the tailgate. Seems that the water is covering a large portion of the rug behind what would be the third seat. I'm gonna have to tear the whole thing out and most likely toss it, but I would like to know where the water is coming from so I don't have the same problem again.

Has anybody experienced anything like this with their GM truck?

Thanks,

-c

The water almost never comes in from the underside (unless you drove through deep water or were parked in it). First thing you need to check is the rear hatch...sit inside with a flashlight and have someone run water from a hose all over the hatch gaps then the roof rack, quarter panel glass. (other leak prone areas: roof luggage rack mounting holes, rust holes, quarter glass loose, prior body collision repair????)

If you want someone else to find this leak for you, take the truck to a body shop. (not a dealership body shop) Let them know you can leave the truck for a day so they can find the leak. They will find the leak then write an estimate to repair it and then schedule the repair. (it may be a small deal and they will fix it right away) Your carpet is history...throw it out and order a new carpet. I'm a body shop manager and prior insurance adjuster/appraiser. I have written hundreds of flood claims/estimates and deal with water leaks frequently.

Why not a dealership service dept or body shop? Work at one for a week or two and you'll figure it out for yourself.

IF it is still under warranty take it to the dealer...

I have the same problem in my '99 Tahoe. I have the liftgate and not the barn doors. My weather seal around the glass hatch slides around and allows water to enter during heavy rains. It channels it down the rear trim post and soaks the rug from the bottom up.

Had the same thing happening, '99 'burban. Checked the seals around the long rear windows on each side. The mounting brackets had rusted a little - just enough to let water pass in heavy rain. One small tube of all purpose silicone later & it's dry as a bone in there.

I would try silicone around the back door and rear side windows first, if that works the cost will be minimal.

Whaddya Want - It's a Chevy.

My '97 Tahoe has the same problem. The rear door design is bad, and it smells like a gym locker in there half the time.

I have a 2000 GMC crewcab, leaked to the passenger front footwell. Took it to the dealer and they have a company come to the shop and fix it. I met the guy, really knows his stuff, fixed the truck in about 20 minutes, knew where to look and what to do. I fought the leak for about a year before I took it in, should have just took it in. Leak was fixed and he warrantys the work for two years.

Hi guys -

Thanks for all of the input. I will check some of the areas that you guys have suggested and see if I can find the source of the leak. I guess when I toss the carpet I could get one of those rubber mats. It will work better with all my fishing gear anyway.

Ludicrous - what kind of body repairs could cause a leak? i ask because I suspect the truck may have been in an accident in the past. I found shattered glass on the rug under the back seat.

Thanks again,

-c

If you have rear A/C, you should check the drain line and be sure it's not stopped up. I had similar problem and a local mechanic looked it over and said the drain line was clogged / kinked causing it to leaking inside. Since I got it back from him I've had no problem.

Chessie

A quarter panel replacement would require the removal and re-installation of the glass...sometimes with less than perfect results. Shattered glass under the seat....take your vehicle to a body shop and ask an estimator to look at it for you and tell you if it's ever been wrecked. He'll be able to point out the panels replaced or repaired. Most shops would be glad to do this for free...it takes about 5 mintues or less to check the entire car.

rdsrb5 is right on too....another leak check is the rear ac unit if equipped.

Thanks again to each of you, gentlemen. You know, I have thought about the rear AC as well. I guess that another thing I will crawl around and check.

Ludicrous, thanks for the comeback.

The bait cooler tipped over in my 90 burb. Different problem altogether, but nasty nonetheless.

Seriously though, my AC line needs cleaned once a year.

Same problem with my 96 Yukon

check rear hatch/liftgate

just tore up the carpet again this weekend - this time it was a leaky cooler.....its designed so that the water gets all absorbed by the sound proofing material and is a B*&%h to take out and dry

Yeah - same here. The rug looks really bad. It has actually started growing some white, powdery stuff. At first I thought it was salt from my fishing gear, but I never let my stuff go back in the truck that salty. Then I started getting red and brown growth. Needless to say, the truck doesn't smell too good. But as bad as the rug is, the sound proofing mat is really bad.

BTW - there are some giant torx 45 bolts hodling some D rings in place. I'm not really sure what they are for, but they are sturdy enough to lift the truck with. Anyway, they are a b*&^% to get out. In fact, I can't get them out. At least one of them appears to have a head pattern that will only let me tighten the bolt, not loosen it. Does anybody know what these are really for? The only thing I have ever thought of using them for is as anchor points for the cargo net that came with the truck.

I'm thining at this point I my ditch the rug once i get the leak problem solved, then go with a rubber mat of some sort.

Hey Chessie,

I've got to agree with the AC as mentioned by others. I had a '95 Suburban where the drain clogged and on a hot humid day it totally soaked the rear carpet. Had it replaced under warrenty. Didn't notice if you mentioned how old yours is but I'd be talking to the dealer. I'm on my 3rd Suburban now and they've all drained a lot of water from both the front and rear on a hot day.

Here is the straight skinny, I have fixes lots of these same trucks for this problem. It is almost always the weathestrip around the door opening. This is the one that is on the body, not the doors or liftgate. I have also seen the same problem caused by cargo mats that people put on their carpet to keep it from becoming stained. This liner causes the floor to sweat and it can never dry out because it gets no air circulation. Carpet pad + carpet + factory mat + liner = smelly problem. If the A/C leaks it will usually be confined to the side where the A/C sits. My money is on the weatherstrip. By the way, don't use silicone, it retains moisture, a bodymay will tell you the same thing, it will rust. Good Luck
