My max passenger side floor get wet but the driver side is dry. I don't think that the sunroof, windows and doors are leaking. Someone told me is leak of heater core. Do anybody have that problem before?

 

leak of heater core.

most likely...

 

Same thing happended to me too, my g/f complained that her foot got water on it somehow, from the bottom of the dash, I touched it, and it was cold wet water. Is it a simple fix?

Finally, I find out the water come from the sunroof. The water leak into the suroof frame. The frame has two holes in the front of both corners. But I don't see any drain hoses connected. Then the water go though the door side rubber to the carpet. I clean and dry the carpet for an hour. Now I just stuck the both holes and clean the water in the frame everyday. Do anyone know that the frame has drain hoses connected? Where the drain hoses go though? Or Change the plactic around the sunroof lid is better?
