93 Sentra coupe: I noticed yesterday that the floorboard of the passenger side was wet, not loosing coolant, but checked that again anyway, it seems to be from the AC but can't reach the end of the drain to see if it's clogged, any suggestions? I've checked the seals, around doors and windows. I've verified it's not the heater core. I also have a rust hole just inside the passenger side door and can see a bundle of wires, maybe it's getting in there? Thanks in advance.
