Why Does My Car Smell Humid?

A car smelling like humid could be caused by moisture inside the car. Some common causes of interior car moisture include wet clothes, shoes, and boots, human breath, damp carpets, leaks from the sunroof, vent system, doors, or windows, and hot, steamy food or beverages. If there is a moldy or musty smell from the air vents, it indicates that moisture is collecting in the vehicle's cabin air filter or climate control system drain lines.

The smell could also be coming from carpeting that has been soaked by rain getting into the cabin. When excess moisture is present, particles like bacteria, spores, and dirt that are pulled in with the outside air can instead settle in the warm, moist evaporator and case, creating a musty smell.
