Thanks so much this is what i see from above is the tube i have put in a black box it ?

PLease someone take a picture of where this drain is. I have a 2020 silverado and the mold/musty smell with onlye 8000 miles on it. I sprayed some Laysol and a mild bleach solution in the air intake and it so far has cleared it up. but i want to make sure the drain is not plugged. no water in cab but i honestly have never seen the typical puddle under the truck when I park it ?
