My 02 tribute is leaking water on the passenger side front floorboard under the glove box. Someone mentioned there is an underbody valve that clogs and just needs to be drained. Does anyone know where the valve is and what it looks like?

 

The A/C evaporator drain is just a short 1" pipe sticking out of the firewall in the engine compartment on the passenger side. If you locate where the A/C pipes go thru the firewall in the right rear corner of the enginge compartment then just look down about 10 inches and you will see the little pipe protruding out.
