Default 40th Anniversary Carpet Wet

Have been having issues with my 370z leaking fluid. It keeps building up under the passenger side towards the rear.

So after awhile of trying to diagnose where the leak is coming from, the only possible thing I can think of is the heater core?

It took about 2 weeks or so for the fluid to build back up. The odd thing is that i haven't used the heater at all. Could the heater core be leaking even when the heater isn't being utilized?

After browsing some of the forums, it seems i can just connect the two hoses at the fire wall and bypass the heater core. Im not too concerned about not having heat as this isnt my daily driver, but I am concerned about the defrost. Will air still blow through the vents the defrost the windshield? I would assume it will, just wont be hot air?

I attached some additional photos. You can kind of see where the fluid is leaking by the lines in the carpet. I pulled the carpet and you can see fluid lines down the transmission tunnel to where the fluid is collecting.

Any info or help would be greatly appreciated!

Thanks,

B
