Hello! Have a 2003 CTS. It is wet under the driver's seat, and I cannot figure out why. I was hoping it was because one of my boys spilled water or something, but yeah, that can't be it. We've had a lot of rain lately, and I had gotten parts of the carpet dry, like where the driver's side rear passenger puts their feet, but it's getting more wet, again. It has been most wet, and refusing to dry right around where the heating duct is under the seat. I am hoping someone here has had the same problem, and can point me in the right direction for fixing it. The doors are not collecting water in them, so they are draining. At night, the car sits on a slight incline with the nose down. Also, occasionally getting driver's door is open warnings, even though door is closed. Thank you in advance for any responses.
