It could be the window sweep set is allowing water in or the door seal around the inside of the door jam and another over look problem is that the heating core is leaking coolant in to the vehicles cabin but the leak would be close to the dash if this is the case
Most water leaks come from around the windshield area. Has the windshield been replaces recently? If so it may not be sealed properly. Another area where water may penetrate is through the cowling area under the wiper blades/arm where fresh air enters the car. There are water drains under this cowling allowing water to drain and if they are plugged with leaves/debris, water will enter the vehicle. Is the vehicle rusted around the windshield area? If so, suspect this to be the source of water intrusion. Most glass/windshield repair companies will diagnose water intrusion problems
remove the door trim and seal of all openings on the inner door panel Door speakers should be in a water proof enclosure ( available from Jaycar or like places) Make sure that the drain holes at the bottom of the door -next to the door skin fold --is clear of mud and rust.
Are you 100% sure it is water IF yes then I would be looking at the door seal (rubber strip that goes around the door) .If no and it could be coolant then I would suspect your heater core is leaking which can be confirmed by doing a pressure test on your radiator.
These water leaks can be really tough to find. In some cases the windshield seal can be leaking and the water runs down the firewall into the interior. I have a similar issue on my Aurora from time to time. I believe the issue is the weather strip around the door seals. It looks to me like the water follows the weather seal and then is wicked into the car where the carpeting contacts the weather seal. I have thought about putting small holes in the weather seal on the bottom edge (facing the exterior of the vehicle) so that the water has a path to follow out of the car. Not sure if this will work.
The best way to find this leak is to use a waterhose, make sure inside is dry them start a slow water spary at the front window and only front glass it is better to have someone inside with a light looking to see a stream coming in, after a while and no leak found start moving up to the top and work your way to rear glass but do this slowly to pinpoint the leak the preson inside must look around also.
It's possible that the seal around the windshield is leaking and the water is trickling in behind the dash area where it is very difficult to see. These leaks can be very difficult to pinpoint and often I've just had to eliminate every other possibility first before finally pulling the glass to find the exact source of the leak. It's a bit of a job but if you can't find the leak then try removing the carpet, insulating pad, and seats completely from the front, dry off the floor, then have someone sit inside with a bright flashlight looking for a leak while you run water over the doors, windows, windshield, and sunroof [if equipped] and you'll most likely find the culprit. It's also a good idea to get the carpet fully dried out so it doesn't get musty and smelly plus it will eventually cause the floor to rust if left wet. Good luck, hope you find your leak!
I have had this problem before, remove the inner trim panel on the rear look down at the bottom of the fender well there is a drain hole there, it is probably plugged up, it is there to drain rain water out of the car that comes in when it rains. Hope this helps, let me know.
