How does rainwater get into a car?

How to tell if heater core is leaking?
How can you tell if the heater core or the A/C evaporator is leaking? Your nose knows! That's because the A/C evaporator will leak condensation, which has no real odor. By contrast, the heater core will leak a 50/50 water and antifreeze mixture. Antifreeze has a distinct, sickly-sweet smell. If you smell antifreeze leaking into the car, a bad heater core is almost certainly to blame.
What happens when a sunroof is retracted?
When the sunroof is retracted, the visible metal frame is known as the sunroof tray. It features drain holes in the corners so , if it begins to rain while the sunroof is open, water that collects in the tray will drain harmlessly onto the ground below the vehicle.
How does coolant flow in a car?
Hot coolant flows from the engine, where heat is absorbed, and taken to the car's heater core when you turn on the heater. The heater core is like a small radiator. The blower fan blows air over the heater core, blowing heat into the cabin to warm you on cold days.
Where is the evaporator drain located?
It's usually located just behind the dashboard on the passenger's side. If the evaporator drain gets clogged with leaves, litter or other road debris, the condensation will have nowhere to go and will begin leaking into the cabin -- collecting in a puddle on the passenger's side.

What causes a slime on the AC?
Bacteria from airflow combines with condensation from the AC coil to produce a mildew/mold smell and the formation of a slime on the AC fins. In addition to normal bacteria, organic material can also be sucked into the HVAC system and land on the AC evaporator fins.
Why does my heater core leak?
When an owner neglects routine maintenance by going beyond the recommended intervals for coolant changes, the coolant loses its ability to prevent corrosion. When a heater core deteriorates due to corrosion, it develops pinhole leaks that allow engine coolant to drain out inside the cabin.
Where does slime go when it plugs in a heater?
At some point, all the slime and organic material plug the drain line. The drain line is a rubber hose that runs from the heater box, through the floor and then to the underside of the vehicle. When it plugs, condensation water builds up inside the heater box until it reaches a seam. The water then drips out of the heater box and onto the floor of your vehicle, most often on the passenger side.
What happens if you have a damaged windshield seal?
A damaged windshield seal can allow water to seep into the cowling and down the inside of the firewall.

What causes water to drain onto carpet on the passenger side?
What causes water to drain onto the carpet on the passenger side? Once the drain tube is plugged, condensation continues to build around the evaporator coil to the point where it leaks out of the HVAC housing case and onto the carpet —usually on the passenger side.
Why does the condensate drain plug up?
When car makers shifted to R-134a refrigerant they had to make changes to the evaporator coil which meant the fins had to be spaced closer together. That tight spacing kept water in place longer than the older style evaporators. As air passes over these tightly packed coils, bacteria can combine with the water and start to grow mold. That mold can morph into slime that eventually clogs the drain tube. In addition, some car makers have discovered that insects are attracted to this decaying organic matter and enter the drain tube to build nests, further clogging the tube.
Why does my HVAC system smell like a locker room?
Musty smell from vents. The science experiment growing in your HVAC system also emits a locker room type musty smell when you turn on the blower. This is evidence that you have mold/mildew growing on the evaporator coil.
How to fix water leaking on carpet?
How to fix water leaking on passenger carpet. Your first step is to unclog the drain tube. That tube is usually located at the bottom of the HVAC heater box on the passenger side near the console. Examine the area with a flashlight and look for a rubber tube attached to the HVAC case. If you have access to a floor jack and jack stands, ...
