I drive a 587 company truck and I am getting water seepage from the edges of the rubber flooring and the padding is soaking wet. The only thing I can think of that is causing this is condensation from the AC not draining properly. I can feel the padding is soaked under a large portion of the rubber flooring. I am also getting water in the fuel messages intermittently on the dash. Are these related? Where is the AC drain at so I can check if it is clogged? What else could be causing this amount of liquid to form, as I have not been in any rainstorms for over a week?
