2007-2013 Silverado/Sierra Owners

[randerson]

I have been working on these trucks and notice a major cab leaking problem and I have noticed some of the worse ones lately when we haven't had any major rains. To make this short I install Truck Toppers and Accessories and when putting a topper on these vehicles we need to hook up a brake light and on these trucks we must run a wire into the cab and connect to wiring under the dash well when I pull the carpet up to access the floor plug that the brake cable goes through I notice that the insulation padding has been soaked. I have pointed this out to customers since I first noticed back in 2006 when these trucks came out. GM is aware of this problem but I have yet to see a fix over the years yesterday I was working on one and the pad actually had some mold on it I think this could be a major problem that needs to be addressed so if you own one of these you may want to look into it. Good Luck

Is there an easy way to see if my truck has this issue? I do find that my 2010 truck windows fog up very easily in damp conditions compared to the 2007 I had. This one is parked outside a lot more also.

open drivers door and pull up door sill and stick hand under carpet if you want to fully inspect you will have to pull the side trim where your parking brake release is and than you have full access to the drivers side floor area. The last one I did actually hand standing water inside the mat was soaked.

Ok Will do, Thanks. So the carpet on the floor is water proof then I am guessing?

[randerson]

It has almost a rubber backing on it

May want to check it the day after a rain storm.

[Capt. H (Ret.)]

I will keep an eye on it. I wash the truck twice a week plus we have had plenty of rain.

You can definately tell when carpet is wet and has not dried out. Had a 99 Tahoe and the rear doors leaked. Chevrolet replaced the rear carpet only to have it get wet again. The second time they fixed it they took the time to locate the leak PLUS put new carpet in it.

I will be definitely check on this the next time we get some rain. The last time it rained I literally had water running out the bottom of the doors. Took it to the dealer and they said nothing was wrong, maybe I need a second opinion.

The only rain that got inside my 2007 Sierra is the rain that came through the broken windows from the hail storm a couple weeks back. The ironic thing is the truck was at the body shop getting a minor ($3000) fender bender fixed. They left it outside after starting work on it and I now have $8000 in hail damage. The good news is that their insurance is covering the damage and the rental car.

The door seals are good though!
