You have water in the floor board passenger back and front but no water on roof a little water on top of door panel. We have had only rain nothing major. The floor is soaked.?

Answer 1

Sounds Like Your Heater Core Is Leaking, If It Is Coolant. Check To See If Your Radiator Is Full & Your Resivor Tank Filled To Correct Level. If They Are Low Fill Them Have A Good Garrage Or Radiator Shop Pressure Your System. The Leak Should Show Up If That Is The Problem.

Not the Heater Core !

This is the solution if your car sometimes has unexplained water on the passengers side floor after it rains and the Blower is working erratic.The solution lies under the large black bezel/cover below your windshield wipers. Under this bezel on the passengers side is a piece of weather stripping that has fallen off. You will see it right away. If you fix this and replace your blower motor and resistor your HVAC will work correctly again. I spent a year trying to figure this out.

Just remove the bezel and check the weather strip. You will be able to see where it was by the discoloration. It falls off by poor design and allows water to seep into your blower motor shorting out the resistor and if left unchecked will smoke the blower motor also. You want to add some silicon sealant and replace the weather strip to it's original position.

As far as the blower motor and resistor it is not all that difficult to replace. You will have to lie on your back on the passengers side to get at it. It's very uncomfortable.

Good Luck !!! Something else to check: I believe the hand brake cable on the 2002s still are designed to pass through the floorboard and the joint is sealed by a rubber boot. If that boot is ripped, water can come up through. Since you'll be taking up the mats and padding, anyhow, to allow the floor to dry completely, might as well turn the garden hose on the suspected water penetration points.
