the vent tube that runs into your fire wall is the drain tube for the cowl. its what brings in the air for when you turn your vent on, if the drain is plugged, water builds up and cant go anywhere so it comes in through the vent ducting, right on to your feet. that was my problem as well. but i also replaced the windshield seal after getting my frame repainted.if you are lookin at your engine the drain tube should be to the left side of the engine back on the firewall.
