1995 Ford Taurus • 6 cylinder FWD Automatic • 140,000 miles

Can someone please tell me where exactly to find the evaporator condensate drain line on a 1995 Ford Taurus GL 3.0L and the best way to clean it out. The a/c does work well but in extreme heat/humidity, it is cold for first 15 mins then goes warm for 10 mins and then cold again. I have checked under car and it is not dripping as it should. Just a drip every 30-45 seconds or so. I believe the drain is obstructed. It has never been cleaned after 140,000 miles. Any help is appreciated.

Those are not symptoms of an obstructed drain. Water leaking onto your floor mat would indicate that.
