I had the same problem with my Accord 94.. this is the drain for the A/C system. its not pluged correctly to drain the water outside. what you need to do is place yourself under the glovebox and u can see a hose it might not be pluged correctly, soo try to fix it up and plug it correctly. it should work trust me.. regarding your A/C it might need coolant to be inserted under the front hood with the blue tap. Ask one of the car accessories and parts for the coolant and where to add it, it cost about 25$.. Good luck..
