Subject: Mitsu Eclipse AC Drain
Question:

Can't find the AC Drain hose on 2001 GT. It is leaking on drivers side floorboard 

Answer: Lisa,
The A/C drain hose is typically located under the car, near the passenger side of the firewall. This can at times get clogged from debris. The easiest way to unclog it is to blow compressed air up the tube and hopefully that will remove the clog. Any mechanic should be able to do that.
Good luck!
