Passenger side footwell is wet

[BMWX5CHI]

I spilled a little bit of iced coffee on the passenger side of my X5 so I cleaned it up using my Bissell spot clean pro. As I popped the threshold from the passenger side I noticed that the carpet was soaking wet from the underside of it. There is some bubbling starting to appear on the surface. Any advice is greatly appreciated. Thank you.

Located the sunroof drains and they seem to drain the water correctly along with the rear drains. All other areas of the interior are dry. The bubbling on the surface seems to only be on the threshold part of the area and is only in 3 spots and i'm sure I can address those properly, but if it's not the drains, where is the water coming from? I'm going to spray the passenger side windshield and passenger side fender/door with a water hose and see if I can find a leak that way. Anyone else run into this issue? What a day to find this out.

Left hand drive meaning leak at right front. That can often be from AC condensation backup. I would track down the drain for the evaporator.

Thanks, I sprayed down her down with water for 20 minutes, no leaks. Going after the drain tomorrow. Now the problem is drying the carpet, especially the bottom part.

What's ambient temperature where you are? Cracked open windows (just enough to vent but let temp get nice and warm) will make it home dry in a couple sessions usually over a couple days.
.summer where I am and 130-140 is typical temp in my black/black car during the day.

Chicago land area temps are going to be high 80's low 90's. I managed to soak most of it by sticking a towel under the carpet and stepping on it. After that I sprayed the area down with Lysol and air dried it. Right now I got the carpet elevated off the floor with a stick and placed one of those bouncy house fans blowing air right into it. I went under right now to see if I could see any drains but no go so I looked online to see what they look like and BMW uses this weird looking drain. Looks like its going to be hard to spot and reach.

Ironically; the best way to remove humidity:

You guessed it: AC.

Blower for max air flow is the best thing next to ac or heat.

Heat + time + air.

You can lift the carpet and run the ac. Check for the normal flood of condensate under the car and then for water dripping out somewhere under the evaporator.

A brother had his evaporator drain plug, it filled the blower cage with water until it flooded the motor and killed the commutator.

Check your door drains. Very common for them to clog and then water overflows the door panel into the sill and carpet. Had it happen to our f15 recently. Also had it happen to one of our e30's and our e70. Don't have a pic of e70, but look for something like this (you can see debris in the front drain):

Thanks for the input. The door was dry and the door drain was clear. I dried everything out and located the evap drains. Cleaned both left and right out. Crossing my fingers this was the issue.
