The most likely cause is a leaking heater core. ... A lack of water dripping under the car while the A/C is running could mean debris has plug the evaporator drain then water backs up and overflows into the passenger compartment. Cleaning the drip tube with compressed air will often restore the drainage.

Why would water be leaking from under the dashboard on the passenger side of a car?
Diagnose and fix water on floor passenger side. A damp carpet or water on floor passenger side situation can be caused by a plugged AC condensate drain line, a leaking heater core, leaking windshield seal, a problem with sunroof drains or water ingestion from the fresh air intake on your car's HVAC system.
What would cause water to leak from under the dash when it rains?
There are diverters built in to this network to ensure that only air, but not rainwater get into the vehicle. If rust holes have developed in this network, or caulking in the joints is leaking, that can account for the water leak to the dash that you are describing.
What does a clear puddle of water under your car mean and should you be concerned?
Some of the most common causes of a water leak are the exhaust, the cooling system, and the windscreen washer system. If you see a clear and odorless fluid under your car, then it's possibly just water from your car's AC system. The air conditioning system of your car is the most common source of water leak.
Why do I have water in the passenger floorboard?
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 rear passenger floor 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 water coming from under my glove box?
The evaporator coil gets cold and condenses water out of the air. The evaporator sits in a plastic box usually under the glove box on the passenger side. The condensed water is supposed to collect at the bottom of the evaporator box and run down to a hose to underside the car.
Why is water leaking into my car?
Most cars have a cabin filter in the engine compartment. The filter often comes with a cover and seals to prevent water from leaking into the cabin. If installed incorrectly, these seals begin to let through the vent, thereby causing leaks inside your car. To resolve the issue, have a mechanic replace the entire set.
What cause water leakage in the 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 water leaking from my car door?
Car doors are designed with drains that allow the water to drip harmlessly onto the road as you drive, but if these drains become clogged, rain and snowmelt can collect inside the doors and eventually leak into the interior. To fix this problem, you'll want to make sure to keep your door drains free of road debris.
Is it normal for water to leak under car?
A few drops of water leaking from underneath your car is most often a normal occurrence. When it's uncomfortable outside and you have the A/C on full blast to keep you from melting into a puddle on the sidewalk, your cooling system is working harder than normal.
What does leaking transmission fluid look like?
Transmission fluid leaks will usually be reddish brown in color with a thin viscosity (new fluid) or brown with a thicker viscosity (old fluid). These leaks will typically be found near your car's middle section.
What is leaking on a passenger side of the car?
Clogged Air Conditioning System Drain
As the A/C evaporator draws heat out of your car, it also collects humidity. Typically, this condensation merely drips out of the car onto the road as you drive. If you've ever noticed a car dripping some liquid from the undercarriage on a hot day, it's likely just condensation.
Why does a heater core leak?
Coolant/antifreeze contains corrosion inhibitors that coat the surfaces inside the cooling system, including the heater core. When the corrosion inhibitors are depleted, the cooling system can become corroded, filled with contaminants and may even start to leak.
Where is the evaporator drain located?
The evaporator coils are normally located directly behind the room air conditioner's front grille. The water collects in the pan underneath those coils, and then drains through a tube toward the back of the unit into the condenser pan.
