Recently noticed soaked and discolored carpet from passenger dash to rear passenger seat. Initial thoughts was water leak from rain, so I took panels off and looked for water... no luck. Yesterday, I pulled all the seats and soaking wet carpet out to discover my AC is pouring into my floorboard. After researching and talking to other Yukon owners, this is a very common problem. I don't yet have a quote, but this looks very expensive. Every owner of this body style seems to have the same problem... and I may never own another American made vehicle after this!
