Almost all the time when I drive my car, and especially when I turn it off (only for about 45 sec), I hear a hissing noise coming from the passenger side/behind the dash. Also, my passenger side carpet is always soaked...could this be an a/c problem?

 

The heater core is under the passenger side dash and if that has a pinhole in it it would make a hissing noise and would soak your carpet. Check the fluid on the floor and see if it looks green and smells like antifreeze.

IT isn't an A/C problem b/c if that was leaking you would pass out from the fumes.

Im having the exact same problem and still cant figure it out. I dont have any leak fluids coming out though.

 

smells like water to me. and that hissing sound is more a bubbling/gargling sound

 

That is definatly sounding like a leaking heater core.

 

You know, I had this after I fixed my a/c, but I haven't noticed it after the first few days. I looked under there, but couldn't find the source. Only did it with a/c on. Cold. No liquids except condensation.

 

i agree thats the only thing thats gonna have fluid running through it in that area.
