This Water is Boggling Me

Lately I have moisture building up in the carpet of my front passenger side floorboard under my weathertech mat. It's only there. I can't find any sign of anything under the truck, and I can't find any sign that water is coming from that AC vent that blows on the feet. Has anyone seen this issue before, and does anyone know any tricks to fix it? It's beginning to smell musky.

Used to happen regularly on my old Nissan XE-V6. Your air conditioner condenser is not draining. Find the rubber drain line under the truck and gently feed a coat hanger up inside of it. Water will start flowing out. You may have to do this once or twice a year.

drain for the A/C evaporator is clogged.

when it clogs, it backs up in the the cabin. there's a thread on here somewhere.

there is a rubber drain thing on firewall behind front passenger tire..... you can use a toothpick and see if its clogged...

heater core leak can drip on the passengers carpet area below glove box.... my 05 i was able to purchase the heater core separate and not the whole unit ...

sorry.... if your heater core is leaking slowly, turn the heater to on position once truck is warm/hot and look from passenger floor mat up into fire wall... you might be able to see the leak or touch the carpet from the firewall on the left side so see where its coming from.
