1999 Chevy Venture leaking AC condensation on floorboards

[stardot]

For the past 2 or 3 years my 1999 Venture leaks (soaks the passenger side floorboard) in the floorboard. Lately, on a recent trip from Colorado to Houston (very humid there), both sides were soaked. Mechanics at the oil change place are unable to locate where the leak is coming from.

Can anybody give me a clue?

Asked and answered many times already. Check the drain tube coming out of the firewall behind the engine. Often it becomes plugged or acts as a wick to bring condensation back into the vehicle. If it's the latter, there is an elbow available from dealers that solves the problem. If it's the former, a piece of wire may dislodge what ever is plugging it...or you may have to tear apart the lower dash to get at it from the inside.

Thanks very much - it's troubling when I can't figure what's leaking. The carpet smelled like dead fish in Houston after being flooded with this condensation.

Thanks again and sorry I didn't see it in previous questions.
