where is the a/c condensation drain located on my 2000 ford taurus SEL

If it's not draining under the car,then the carpet should be soaked on the passenger side front floor, if the A/C is working correctly. The drain on the firewall, down pretty low just to the passenger side of center. It is oval in shape and barely sticks out. To unclog get a coat hanger and straighten it out. Use the coat hanger to go into the hole and wiggle it around a little,and it should unclog the debris. BE ready for water to come running out when you get the debris free.
