Why is back passenger floorboard wet?

The A/C evaporator draws warm, humid air out of the cabin and allows the water vapor to drain out onto the road as you drive. It’s usually located just behind the dashboard on the passenger’s side. If you notice a seemingly-random puddle on your passenger side floor mat, it could be a bad A/C evaporator drain.

Why is my floor wet when it rains?

Why are the floorboards in my car wet?

Water present on the floorboard is usually caused by one of two things. Water is circulated into the passenger compartment through the heater core. The heater core is heated by the engine coolant. If this hose becomes restricted, the water that condenses on the evaporator core will leak into the passenger compartment.

Why is the floor of my car wet when it rains?

It’s usually caused by an HVAC system component in the dashboard leaking into onto the floor on the passenger’s side. As it works to keep your car cool, the A/C system creates a lot of condensation. This condensation normally drips down the evaporator drain hose and onto the ground harmlessly as you drive.

How long does it take wet floorboards to dry?

Don’t be surprised if the meter still shows signs of moisture in the floor after a day or two. It can take up to several weeks for wood flooring to completely dry. Also, the humidity in the room and the amount of water that was present on the floor can prolong the process.
