Carpet wet on drivers side... again!

[Mark Francois]

I've began chasing a water leak in my 2003 GMC Yukon with NO sunroof since last November and finially found the leak and sealed it up start of January. Carpet has been dry since then until last Wednesday when I found the front drivers side carpet damp. Well, I dried the carpet and jute mat up the same day and wasnt able to find a leak anywhere using the water hose. Carpet was dry until today where it was damp again but we havent had any rain. I ran the AC non stop today so my question is, is there a drain for the ac that if pluged would cause the drivers side carpet to be damp. I checked the drain under the hood on the passenger side and it was clear.  I mean the carpet was bone dry yesterday and now today its wet... no rain, no carwash, no spilt drink and the wetness does not smell fishy so I dont belive it to be the heater core plus it is the drivers side carpet not the passenger side... no nothing. Any ideas??

Any thoughts?

For my truck, the P.O. replaced the driver's door hinges and did a really bad job of it, and water leaked in through the replacement hinge bolt holes.  Hard to find as the water would run down the inside of the A pillar down to the floor, then come out.

Go about halfway down to the picture of the blue Silverado.  That was this source of my leak.  I only used silicone and did not use the piece of aluminum, and it has not leaked in over 3 years.

The first leak I found was similar in the way is was coming in only in came from some seam sealer that had cracked near the top of the Same pillar.

That strip confuses me. It unbolts from the body and serves as windshield moulding so it shouldn't be the direct cause of any leaks unless the windshield itself leaks but lots of folks say it solved their issues. We have checked the windshield and no leaks there but I wonder if my leak could be traveling from one cavity to another?

What I did was to "roll back" the rubber strip and put some clear RTV over the metal joint.  No more leaks.  My windshield did not leak.  I agree that it's in an odd location, but then again, I did not find any other leaks by running water over the windshield and roof.

Damn it I found it! Finally!!! The inner plastic liner behind the door panel was not completly stuck to the door frame. Back in October I replaced the window regualtor and failed to make sure it was tacky enough to hold and so when it would rain, the water would splash on the plastic and run down between the door and panel, onto the plastic threshold and then onto the stinking carpet. I wish that I would have discovered that before I replaced the door seals because now you have to slam the drivers door to get it to close. I was hoping after a week or two the door seal would have relaxed and become easier to close but no luck yet. Any advice on relaxing the door seal so the door will close without slamming lol

Congrats!  Thanks for letting us know!
