Hey all,

Just like the title says... I got into my truck a couple of weeks ago to the smell of "I left my well worn soccer cleats in the truck after a workout in the summer with the windows up" smell. You know the one, musty and mildewy.

I felt passenger carpet and it was wet. A few days of running the AC and leaving windows down in low humidity helped. But next time I got in my truck, it was back.

Cue me removing trim and pulling up front passenger carpet. Yep, it's wet.

I do not have a sunroof, and I checked the evap drain. No evidence of clog, no evidence of a leak emanating from that area.

I have Weathertechs, so it's unlikely a spill happened that soaked the carpet. Likewise, I don't think I left the window down for any appreciable amount of time.

There was some heavy rain on a few short drives, but I've never had water intrusion issues before. All body plugs and door gaskets over there seem to be in place.

Any ideas on what else could cause this? Thanks in advance!
