So I've been trying to track down an odor in the Jeep. Thought maybe something I bought for dinner may have fallen out while driving home from the store and started going bad. So I went through the other day and removed anything that may have touched food and left the windows down for a few hours at night. Still getting a smell. Talking with a co-worker today, I realized I never checked under the rear seats. So I checked after work and found this under the drivers side rear seat well: There was a old pack of smokes in the puddle, which I think explains the brown color. The surrounding carpet feels dry, so I don't think it's coming from the door. Also, there are boxes and papers on the seat above it, and none of them appear wet or have been wet. Soaked it up with a towel, but was wondering if anyone can give me an idea of a source.
