So I have a question, dose any one know how water would be getting in the rear driver side foot well of a dodge caliber. It's my dad's car it's an 06, I don't know how long it has been leaking as he never noticed. Mom noticed today when she went to put something in the back seat. as there where 3 to 5 (it submerged a road side emergency) inches it was about a half inch from the top of the hump between the front driver foot well and the rear driver side foot well under the driver seat. it is also clear from the small amount of water in the front divers well it has gone over the hump ether during heavy rain or when he drives down the hill we live on. there is not water in the in the rear or front passenger foot well so I don't think it would be a plugged drain for the HV/AC system as to me that would flood both front (from foot well vent) and rear foot well (from the floor vent to the back) Is this a common problem? I don't think it is a door seal as I would hope my dad would notice (but given that he did not notice 3-5 inches of standing water in the car I don't know) the amount of water leaking in coming into the car that way. Is there a know problem like this? and where would the water be coming from?
