There is a leak somewhere and it can be from the windshield, doors or pillars. You would need to perform a water test to locate the source of the leak and repair accordingly.

If possible, remove the carpet and use a garden hose to spray water onto the vehicle, dividing the test onto separate areas starting with the lower part of vehicle and rising up to higher position. Any leaks should be noticeable from inside cabin.
