Passenger Carpet Soaked Underneath Floormat

[brandonbvr]

Has anyone run into this issue? My passenger side front carpet is soaked when I picked up the floor mat to go ahead and vacuum. It's only wet underneath the factory Floormat. No I did not spill anything. Any thoughts?

on star atenna, sun roof or heater core not sure if the long life coolant still has that sweet smell

Trying to narrow it down. I don't have a sunroof. It's deffinately water and the passenger floor is no where near any roof attena

Do you have airconditiong, maybe the evaporator drain is off and the water is not routed to the outside of truck.

Just a guess here. Body Grommets, or floor pan seals missing, handbrake rubber grommet damaged?

^{Heater cores have been known to go out early on these 14's. Check your coolant level to cross that one off your list of possibilities.}

When I had a 2001 Dodge Dakota, the passenger side carpet would always get soaked and short out the air bag causing a light to go off in my dash. For years my Dad and I chased the problem to no avail. Finally I started to notice that the problem occurred more in the summer than in the winter so I started to speculate that it might be related to the AC. Sure enough I ran the truck with the AC on and started feeling around under the carpet with my hand and I could feel a slow steady drip of cold water coming from below the dash. Long story short Dodge, and most other Chrysler vehicles including Jeep, had an issue where the condensate drain for the AC would get clogged with insects and it wouldn't drain. The condensate would back up and start overflowing behind the dash and draining into the interior of the truck. My mechanic could blow compressed air through the drain line under the truck and that would help for a few days but eventually the insect debris would work its way back toward the drain line and clog it again. The only fix was to pull the dash out and clean the condensate line from the inside and try to put some type of protective netting to keep insects from getting back in.

 

So, if you do not have water coming from your ceiling which would most likely be the leaking XM/Onstar antenna issue, my money is on your AC condensate backing up into the truck.

So my coolant level is normal and my A/C is draining in the proper spot after checking. This rules out the heater core and evaporator issues. No spots on headliner. Washed the truck prior to vaccuuming so water is coming in from somewhere. Goes to the dealer tomorrow I'm hoping they figure it out. Took off the kick plate and water was trapped under the insulalation and carpeting.

Might have a bad seal on the windshield. I know a guy that had a leaky windshield (not a 2014) from the factory, so don't rule that out.

 

Some were having problems with the OnStar antenna seal leaking on the drivers side.

Take a close look at your front windshield lower weatherstripping that intersects with the bottom of the glass, i.e. between the hood and the windshield where the wiper arms are. That seal was not fitted properly on my new '14 Sierra Denali and in fact had a 1/8th-3/16" gap, requiring the dealer to change it as a OEM defect. Luckily I noticed it when I inspected my vehicle the day of purchase otherwise could have easily ended up with some water encroachment as the weatherstripping was not touching the glass.

Thanks guys I will look into the windshield seal and associated weather stripping.

Believe it or not, I had the same problem and it turned out to be the seal around my 3rd brake light.. When ever it would rain it would travel all the way to the front and soak the passenger floor. That was on a 2001 Silverado but still something to check.

[brandonbvr]

Got the truck back from the dealer and they were unable to get the result of a water leak under their testing. They said more than likely my AC drain was clogged. We will see what happens when I have the time to wash it next.

I had that problem for years on my 04 sierra 1500 .....vould never figure it out

[Luster]

Yeah, I'd bet on evaporator drain.

[Tattooo]

Your prob right....I always thought it was a leak from rain....but it was slways there after vaccuum & shampoo
