What would cause water to leak from under the dash?
Water on floor passenger side from clogged AC condensate drain. This is one of the more common problems. It’s caused by bacteria buildup on the AC evaporator coil located in the heater box under your dash. The water then drips out of the heater box and onto the floor of your vehicle, most often on the passenger side.
What causes water leakage in a car?
Coolant may leak from a car for a number of reasons. The most common are: radiator corrosion; a damaged coolant hose; or a water pump with a leaky gasket. In the vast majority of cases, water leaking from under a vehicle is usually condensation from the air conditioning system, or from the exhaust.
Why is my floor board 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 in the back of my car 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.
Can coolant leak when car is off?

Chances are you have either a radiator cap leak, internal coolant leak or an external coolant leak. The longer you wait the higher the coolant leak repair cost will be.
Why is it wet under my floor mats?
Heat under your floor mat comes from the exhaust pipes, and causes moisture trapped in the carpet to steam and collect on the bottom of the mat. The moisture under your carpet has to come from somewhere and that somewhere is almost undoubtedly the air-conditioning system.
Why is the carpet in my car always wet?
