Well, the water leak is finally fixed in my 2005 Duramax. After repeated trips to the dealer and trying to find the leak myself, it is finally taken care of. For anyone else with a mysterious leak, mine turned out to be the rubber boot that encases the wires coming from passenger side door to the cab. It was not sealed properly and was letting rain water in. I now have a severe mold problem under the carpet. I am going to remove seats and clean/dry carpet myself. Any helpful tips? I need to replace that padding that goes underneath the carpet also. Does anyone know a good place to get this stuff? Thanks.

Glad ya got the leak fixed..... Sorry not much help with where to get new stuff.....
