Wet carpet: 2006 ST wagon. Front passenger's floorwell

I have a wet carpet too. lifted the mat and it was soaked underneath
I haven't searched for the leak yet but I can almost guarantee it is the air con drip pipe which has fractured or a joint come apart.
It normally discharges through the bulkhead and drips outside.
I had an identical problem in a 2000 pathfinder.
It is not a leak from the screen, it hasn't rained in months. and it doesn't smell of coolant. just clean water. like you would get from an air con.
It's worse in the hot weather, when the air con is going flat out
Will let you know when I find it.

Pull up the plastic kick rail, lift the carpet and look underneath - if your coolant is green and the moisture is green then you know what it is.

Air con drain can also block and it will fill under the evaporator until it overflows and runs into your carpet, if its that you can find the pipe underneath and try blowing some air into it from a compressor. It should clear the blockage and mean no pulling apart.

Try to check the evaporator drain pipe which protrude unto the engine bay, so locate it under the hood. if the drain pipe is not provided with a hose extension then you just found the culprit of the wet cartpet. Condensed water wont drain when you drive fast enough wherein air pushes the water back to the evaporator casing. Water then drains under the dashboard, now wetting your carpet. During long drive, as if you got a pail of water spilled on that carpet. Solution: look for a rubber hose about 6-8 inches long should be aware of its inside diameter and push it on the protruding drain pipe. Tie it to secure. There could be a coil nearby to tie unto. if none, cut a longer hose that could reach a tie point.

Hope this could solve your wet carpet, i call it a nightmare!!

Take the glove box out (6screws) for a better look.
