Q: Rain getting into car

I would need a little more information for a proper diagnosis, such as the location where the water is entering the vehicle, and whether or not your car has a sunroof. If you have a sunroof, the most common leak is due to the roof drains getting clogged, causing water to overflow into the vehicle when it rains; it would get into the floors, or drip from the roof. Other than this, the leak would have to be isolated, and identified, by an experienced mechanic; I recommend having a mechanic, such as one from YourMechanic, come to your for a proper diagnosis.
