Since they can't find it then you will have to. Remove all the trim panels holding the carpet down and fold the carpet back to the front of the seat and dry the area very well. I use baby powder and cover the floor board with a solid powdering. Now shut all the doors and windows and sit in the car and have someone soak the car down really well to find the leak origin. You need to see if it is dripping from anything or running in from elsewher. You will see a trail in the baby powder. Most common leaks are the air inlet under the cowl at the base of the windshield. This will cause the blower to sometimes fail and the water to drip from the base of the blower under the glovebox. Other possible leaks can occur from a evap case drain. Above the passengers left foot toes wayt back up in there in the floor board. Anytime you use MAX, AC, PANEL/FLOOR,FLOOR/DEFROST,DEFROST the compressor is turning and removeing humidity from the air. So if the EVAP case drain is clogged or leaking the water will caome back in the car there. No I do not believe the water is affecting the door ajar unless the door is actually open and the source of the leak. The door ajar sensor is inside the door atttached to the latch.
