Hello everyone,

There was recently a storm here in California but it has been dry this week.

Just on Monday (December 2nd) I noticed when I got in my car, a 1999 Buick Century Custom, in the morning that the inside of the front windshield had a significant amount of condensation on it. My steering wheel cover felt a little damp, as well. I checked the floors in front and the floor on the driver side felt just a tad damp underneath my floor mats. I checked the floor in the back and behind the driver's seat is completely soaked. The bottom of the backseat is damp and so is the floor behind the passenger seat. The passenger seat floor in front seems to be the only area that's dry.

The weather stripping around all four doors seems fine. It's a wee bit cracked on the back driver side door. One canvas shopping bag has mildew on it that hangs from a hook on the back of the passenger seat headrest, other reusable shopping bags are fine. It does smell like pine trees in my car now which I assume is mold.
Since I don't have a sunroof that's not the culprit, should I have the weather shipping replaced just for the fact that it's 25 years old? But if it's not the stripping, what is causing this leakage? My carpet looks like it would need to be replaced. Of course, after the leak is corrected.

Thank you in advance for any ideas. I can provide photos tomorrow if needed.
