If you have a sunroof, open it halfway and then pour just a little cupful of water into the channel, you should see a drain hole. Make sure the water drains out the bottom of the car.
You can test the same thing in the fresh air vents just below the windshield wipers. If you pour a little water in there (simulating rain water intrusion) you should see it dribble out the bottom of the vehicle. If one or neither of these drains does not drain out the bottom, it is plugged and going into the passenger compartment.
