We just got the civic and notice water leaking on the passengers floor when the A/C is on. Where is the A/C drain outlet on the Civic?

At the passengers foot well area underneath the glove box area you will see a black plastic housing with a short 90 degree black rubber hose. the hose has probably fallen of the little fitting that is secured to the firewall and allows condensation/water vapor to exit the heater/ air conditioning unit.
