I've been having this problem as well with my 2002 Eclipse GT. I took it to the shop and supposedly the line that drains off condensation was blocked and leaking the water elsewhere in the cabin, which in my case made a miniature lake behind the driver's seat that was treating the electronics underneath nicely, I'm sure.
The problem was solved for a while, being about less than three weeks, but then started flooding again. T_T
I'll have to have someone take another look at it, if I don't come up with any answers soon. But I would definitely check to make sure none of those tubes have corroded or been blocked.
I'm not too knowledgeable on the make of air conditioners, much less even my poor ol' Mitsubishi, so any other further information would be delightful. Driving in the Florida hot sun with an all leather interior isn't too pleasant without working A/C!
There is a special website of eclipse fans where you can find answers to any questions you have about your car. See below.
It's inside of water outlet.
For me it's sound like you have problems with the right door. Check the rubber/palstic parts around the door.
No, it causes a massive coolantleak.
If you have a plugged AC condensation drain, clear water will back up and end up on the passenger floor. If the heater core is leaking engine coolant you will have engine coolant end up on the passenger floor.
There are several things that can cause your 1992 Mitsubishi Eclipse to overheat. A malfunctioning water pump or a blown head gasket should be the next things that are checked.
Are you running the air conditioner? If the drain line is plugged, it will leak water (condensation) onto the passenger side floor.

Might Be Yr running out of oil, or water levels are low.
You can find it in the water outlet (the upper hose connector which joins the hose and the engine).
