Hello,
I have searched all over the internet but i have not found any help. I own a 2005 honda civic EX and the passenger side of my car keeps on getting wet floors. I’ve checked to see if it was from my sunroof, or windshield but I can confirm that it’s from neither. The water seems to come from behind the black rubber thing that sits behind the carpet on the passenger side. I’ve also tried to blow compressed air into the a/c drain hose but nothing came out. I’m stuck and don’t know what to do, I just don’t want moldy carpet.

 

The cabin air filter is there as I remember , perhaps a problem with the fresh air vent ?

 

If coolant leaks from heater core it will smell sweet like coolant in that area.
