I am getting condensation from ac on my back seat floor out of the right side of the floor vent. I hear that there is a port that can be cleaned out to drain to the outside. Is this true and if so where is it???

Is this from water coming out of the main AC unit on the passenger side?
There should be a drain to let moisture out of that, where any time you drive much on a humid day you should see a pretty good flow of water coming out just in front of the passengers feet on that side.

The drain may be damaged or plugged up either within the A/C unit or underneath the vehicle. If plugged inside the AC, usually due to fungus/mold build up.
If you can locate it from underneath, bend the end of a coat hanger very very tightly so you have about an inch or so bent sharply over [so it can't catch on anything] and CAREFULLY see if you can clean the drain.

You might have to open the A/C itself, which is kind of a pita.

If mold/fungal growth, once cleaned out, try spraying it with Frigifresh a couple times a year to keep growth down.

Ok this is the ticket. I learned a few things from his repair. One you need a slightly larger hole to work from. The actual drain to the outside is in the center of the circle. The plastic of the circle is thick (about 1 inch) it was corrugated; I assume to act as a filter or trap so debris will not clog the hole. I used a 3/4" fosner bit to bore thru. A few good blasts of air opened up the drain which runs inside the frame. :eek: (You will never find it from under the vehicle!!!):slapfight: I found a plug from a pool pump that worked very well.
