I was riding in my vehicle listed above when I dropped some crumbs on the floor mat of my passenger side. When I took it off I noticed that the floor was drenched and that there was a strong mold smell. I took all the floor mats out and hanged them to dry but on occasion, I find that the floor gets wet and on some days it's bone dry.

Hello,

It sounds like the evaporator drain is clogged and the condensation is draining inside of the vehicle instead of to the outside.
That drain is located on the passenger side firewall (in the engine bay). It is located low on the firewall closer to the center. It should be a rubber hose that drains the water. Check for any dirt or debris blocking the drain.

I have attached a diagram that can help you locate the drain.

Let me know if you have any questions.
Thank you.
