    Default 08 Silverado Interior question

    Hi there fellow GMTruckClub members!

    I'm new to the site but have a crazy question about the interior of my new 2008 Silverado ext. cab. Recently with the cold weather descending on NH I have had incredible amounts of condensation occurring on the INSIDE of primarily my front and back windshields every morning. I have talked to numerous people about this phenomenon and canít find a cause or solution. My windows and doors are shut tight every night so I canít figure out where all the water is coming from. I would really appreciate any ideas!! Lastly and for a real twist the rear passenger side head rest is soaked as well. I can not find a leak and the head rest does not make contact with the window!

    Thanks so much,

    cwi2

    well if the truck was like 15 years older i'd ask if you had any moisture on the floor and then say maybe a faulty heater core but given the vintage that seems unlikely....i'm stumped, especially with the wet headrest. any chance this is a plow truck with perhaps a light rack installed?

    I would have to say that you should look for a leak somewhere on the roof. For the headrest to be soaked like that, that's just weird. Got a buddy tryin to mess with ya or anything? lol.

    Well, I think you may have answered your own first question. I would think that a wet headrest (or anything else that was wet on the interior!) would be a good explanation as to where the moisture INSIDE the cab is coming from. Now... as to WHY the headrest is wet... that's a whole different question and problem.

    Remove the headrest, feel for any other wet places in the cab and see if the condensation on the windows ceases. While you have the headrest out.. TOTALLY dry it out as quickly as possible. Put it in front of a heater vent in the house or something.

    As for if it's possible you have a leak in the truck... see anything else gets wet - like the seat itself with the headrest off. If anything else is/does get wet, then what I would do it use paper (like newspaper) to cover the main parts of the cab. Every hour or two, or after an overnight, check the paper carefully and if you have any leaks from anywhere they'll show up on the paper. Look straight up from there and you'll see where you are leaking from.

    Just my $.02.

    Hey fellow club members!

    Thanks for the ideas, I figured I need to remove the headrest from the rear passenger side that is wet and that could be the start...any ideas on how to do that? I havent been able to find any leaks of any kind in the interior either.

    Thanks,

    cwi2

    Take it to the dealer and tell them to fix it.

    X2 Warranty is there for a reason. Any chance you have a sunroof. My last Chevy car with a sunroof had issues with leaking. Took them four trips to fix the dam thing. Also I would btring up to them to replace any interior parts that are getting wet as well as mildew will set in and stink pretty bad.
