Damp floor under rear seat

[xFURIOUSJONESx]

I’ve noticed that every time it rains, the interior of my truck smells musty and feels humid inside. Today I noticed the carpet under the backseat...near the far back was damp. I checked the third break light for any leaking and everything checks out there. I’m wondering if anyone else has experienced this?

It’s almost as if maybe water is getting kicked up from underneath the truck somewhere from the wet roads.

Rear window or 3rd brake light leaking. Try resealing the light first

Checked third brake light. No leakage there. I’ll check the rear window.

Dump a 5 gallon bucket of water onto the rear top of the cab and see where it comes out.

There was a factory seal kit added to my 2015 HD rear sliding window area. Not sure if this is where your leak is coming from. Have a 2nd person put a hose with no nozzle to let the water flow over these areas while you are inside with a bright flashlight.

It can also be the cab vent behind the rear seat. Mine leaked from there. It took the dealer 3 times to finally figure it out.

Just to add to the above advice, it can be difficult to pinpoint exactly where the water is entering unless you drop the headliner.

I had this problem with my 2017 ram 1500 quad cab over a year ago. I put new gasket material on the 3rd BL, the dealer put on a brand new 3rd BL and in the end it wound up being from a shoddy aftermarket rear window install was the leak source.

This window was put in by the previous owner, so I had to pay a glass shop to remove and reseal. It was the glass shop that ultimately found the leak.

This was my problem. I had to take it in 4 different times for them to find and fix the issue.

Ended up getting all the carpet, mat, and insulation for the whole truck replaced. It was molded and smelled terrible inside my truck. Sad considering it wasn't even a year old when the problem started.

Mine was a month old. So my carpet were not moldy yet. I caught it early. The dealership thought I was lying to them and wetting my own floors. It was so ridiculous. Then I caught them charging me for 8 qts of oil for a oil change. Hemis only take 7 quarts. That was the last time I ever took it to them for service. Imagine all the extra money a year this dealership is making of of charging for a extra quart of oil on every hemi oil change. Unreal.
