Water leak

Have you tried any of the cleaners or fogger bombs for vehicle vents? Other than that you’d probably have to take everything apart and clean everything and then put it all back together.

How often do you change out your cabin air filters? That could also be a source of funkiness.

 

whats a semi?

Semi what?

Call a vehicle flood specialist, depending on where you are at, they will charge anywhere from $200 to $400 for a good cleaning.

 

Spray some Lysol into the intake. Outside set on normal, going through each setting. Vents, floor, defrost. Then do the same spraying into the inside intake. with it set on recirculating. You can take the fan out and spray the coil with a hose, letting the water go out the drain. Other choice is to pay a shop by the hour to disassemble the dash, take hoses off and clean or replace them. That’ll be expensive. Lysol kilns everything. New fragrances available. I suggest the “fresh linen” Lol,

 

I’m going with Long FLD and changing the cabin air filter.

 

Nope. Its an aftermarket accessory on most (maybe all) B cab Kenworths. If it had one added, it'd be on the side of the cab, over the inlet behind the right side air cleaner.

If you don't have one, I recommend it if you're in the dust and dirt a lot. The dust will eat the blower motor pretty quick - year or so max they'll last.

Lysol and an AC or dehumidifier. Open bowls of vinegar???
