water in floor board when a/c is on

There is a small diameter hose that goes the passenger compartment (interior of the vehicle), it allows condensation caused by air conditioning operation to exit at the rear of the engine compartment at the passenger side under the dash just above the carpet level. The hose removes condensation created by the air conditioning system that is working efficiently so that water/moisture does not remain in the heating/air conditioning unit behind the dash otherwise the stagnant water would become stall and cause an odor. The hose frequently gets knocked of by accident by a passenger's foot. Open the passenger door and look for the hose, reattach it to the little spigot on the foot well area and the water will then exit into the engine compartment where it will harmlessly drop on the ground outside.
