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.
