Soggy carpets on driver side only every time I cut heat on or A/C on.

Good afternoon,

There is a drain hose for the housing that allows water to drain out to the ground. When that clogs up from dirt or debris, it backs up in the car and on to the rug.

I attached a YouTube video for you to view the location and procedure to clean it out.
