AC Leak into passenger floorboard

The water is coming from the evaporator coil. The tube that is sticking out on the engine compartment side is the evaporator condensation drain line. It appears its plugged up and backing up into the blower assembly. get an indoor/outdoor vac and put the hose to the drain line on the engine side firewall. When you put the vac hose on it, make sure you cover it to prevent suction loss. You want all the suction coming out the drain line, not leaking along the side of the hose.. This way it'll force a lot of crap out of the evaporator coils. There is most likely algae buildup inside.

Oh...and your gf is hot lol. Well hey..you posted it...hehe

LOL, I was waiting for someone to make a comment about the pic...heh.

The towel you placed on the floorboard was steaming hot? If it was a hot steaming wet towel, I would def suspect a heater core leak. You didn't by any chance pull that black tar insulation away from the firewall did you? The exhaust gets very hot in this area. The converter underneath, at least on mine does not have a heat shield on top. Seems like it was built that way. Either that or it went missing somehow. Anyway, if it isn't coming from the heater core, then the exhaust is heating up the floor pretty good. Enough to get the water leaking out hot. If it's THAT hot, i'd check to make sure you're converter isn't getting plugged up or too hot. Don't take the black insulation away from the firewall. Doing so will allow a LOT of heat in.

Once when one of my converters got red hot, the interior of my car started to smell like something was burning. My carpet was out at the time. It turns out the floor had gotten so hot from the burning hot converter that it started cooking the adhesive material on the floorboard.

I hope you didn't use a regular floor vacuum to suck up the water. If it wasn't meant for water, you could damage it .

Go ahead and use the carwash vacuum. Who's gonna care...heck, do it at night if you are concerned about an employee noticing hehehe . and no, that drain on the firewall isn't supposed to have any other pieces attached. It just drips onto the hot converter below. I remember awhile back I didn't know what this noise I was hearing was. Every time after I shut the car off after a drive and got out, as soon as the door closed I heard a SSSsssss noise, like something sizzling. It was water getting shaken out of the drain tube and landing on the exhaust I eventually found out.

my 2000 mustang does the same thing it seems to only happen when i run my ac im in the same boat
