Finding a pool of liquid inside or outside your vehicle is concerning. While auto repair professionals have the tools to quickly diagnose what could be wrong, there are also instances when you can figure this out yourself. Here’s more information about different types of leaks.

Common Causes of Rainwater Leaks in Cars

Sealing Issue

Your car has multiple seals that line the doors and windows, also called weatherstripping. If these break down or crack, water will start to pool inside when it rains or snows.

First, determine where the water is accumulating. This could be in the back, front, sides, or near the middle if you have a sunroof. Use a paper towel to wipe the weatherstripping in any nearby glass. This will help you see any damage.

Air Conditioning

It's normal to see water underneath your car after using the air conditioner, except when that liquid finds its way into the interior. 

A clogged drain tube will cause water to collect underneath the dashboard and the front carpets. If this is happening, don't use the AC until you visit an auto repair shop.

Air Filter

Car cabin air filters that are installed in the engine compartment will leak into some cars if they aren't fitted correctly, or if the lid isn't secured.

Although this problem isn't necessarily dangerous to drivers, it could cause electrical malfunctions underneath the hood. You’ll need to have these components replaced.

Why It's Important to Address This Immediately

If water is left to pool inside, mold may start to appear. A damp car will also smell unpleasant.

A fluid leak could also be mistaken for a rainwater leak. Fluid leaks indicate problems with the transmission, AC, or tubes. Getting these checked will help you avoid costly damage and inconvenient breakdowns.
