Flip Flop....Drip Drip

Last night my son and I were coming home from a 99 chow-down. My son was in the passenger seat and wearing flip flops. The conditions were "moderate rain" humid and my A/C was on. He felt water dripping on his left foot (nearest the console). Before I go talking to the dealer (still under wtty), what is your experience with this on a 15' DC?
Thanks!

 

Hmm, this could explain why the passenger's carpet is always slightly damp under my WeatherTechs. Be interested to hear what it is.

 

Could be a blocked up AC drain tube.

 

I will add a few searched resources here:

Blocked AC drain me guesses. When you get outta the truck do you see a puddle where the drain drips. If not its probably clogged. Easy to check too.

 

Only thing that could possibly have moisture coming from it in the dash would be the AC system. Literally nothing else up there should ever get wet.
