water on drivers side floor
Hello,
I have a 2000 Pontiac Trans Am. Recently, I noticed a smell in the car and realized it was coming from a wet spot on the driver's side floor. I cleaned the rugs, but the wet spot seems to come back. I pulled up the rug and noticed a round rubber "plug" of some sort under the spot where the water appears. I haven't tried to pull it off. Is this some sort of drain? I'm not sure what its purpose is? Could this be allowing water to get into the car from the outside? Any thoughts?
