Moisture under front and rear passenger floor mats

Hey!
I’m noticing that my front and rear passenger carpet is all wet underneath my floor mats.
The truck has issues with windows fogging and never clearing up, maybe this is related?
What could be causing this moisture?
Thank you so much in advance for the help

Make sure the evaporator is draining onto the ground- run the AC and look for water on the ground- it exits thru a rubber tube on the bottom of the firewall, passenger side, on my truck. It needs to be a humid day to verify this.

Verify you're not losing coolant and have a heater core leak.
