328i condensation issues

My 2000 328i is fogging up every night that it rains. My floor mats are slightly damp on the drivers side, but I checked for leaks and it doesn't look as if there can be an issue anywhere. What else would cause this? aircon?

this kind of leak will not show visually, check if the draining holes are clogged.

Where are the draining holes located?

Bottom of door. You may also have a failed door seal. Door panel has to come off to see. Anyone do any work inside the door before this problem showed up? Could also be A/C drain plugged up. Do you see water dripping under the passenger side of the car?

I don't see any water at all dripping period. I feel like it's an AC issue. There are no visible leaks anywhere and there's condensation on the windows every time it's cold out. It's to the point that I have ice inside of the windshield that I have to dry off with a towel. The car is perfect other than this issue. How do I go about checking to see if the AC drain tube is clogged? Because that's my gut feeling as to what it is since the water is spread out throughout the car. there are no spots of water, just light condensation on floormats and a high amount of condensation on the windows.
