94crownvictoria back and front passenge has pooled water,i have no idea from where or is this commonr

You may have a plugged AC water condensation drain hole, it drains under the car at the base of the engine bulkhead on the passenger's side.

You should also check that the front windshield is sealed tight around the frame at times roost could have eaten away the metal under the Rubber seal this was the cause at one of my cars.

Have you had front or rear glass changed? Is there rust around windshield or rear glass? Have someone run water hose over upper glass...while someone inside car inspects for water trail. Hope this helps.

Most likely the ac drain is stopped up. The drain is under the car near where a passenger feet would be. You can try gently running a pencil or something similiar to clear it out or compressed air.

windshield gasket. if windshield was recently replaced, it was not installed properly. get it fixed quick or it will rot the carpet, rust the floor, and possibly cause massive electrical problems

Look for moisture on the glass of the windshield, as well as the passenger side door, if thebottom seal isnt making contact on the door glass water will run in threw the door

I suspect that water is pooling in the cowl area (in front of the windshield). Since it's at an angle, the water can't drain out the usual drain. This is also where the air is drawn in for the heat/a/c. I think that the water that collects is flowing in through the climate control system and coming out the floor vent. If you want to test it, jam some paper towels up in the floor vents and recirculating air intake and see if they get wet. If you just want to solve the problem, try backing into the space.

My dad has a 2004 Dodge Dakota with the exact same problem, the passengers side floor board is soaked with water after running the AC. Also there is a pool of water that collects under the truck.

We are getting a mechanic to look at it, I will post what the problem is when we find out.

have the dealer water spray test the body seams, that is the only way to find these leaks..

I have a 96 crown vic and had the same problem. There's a drain for the firewall that causes the leak. Water flows down the windshield to the drain and out the bottom to the car. Ford put the drain on the inside of the firewall and if a gasket fails the water will come in the car. The drain is on the front passenger side of the car. The best way to get at it is to jack up the car and remove the front passenger tire. If you pull back the plastic wheel well, you will see the drain on the firewall of the car. Its actually a very easy fix, just use some GE silicon around the gasket area. My back floor would flood out when it rained. I pulled the carpet out and the passenger seat, but you'll never find the leak from the inside of the car or under the dash, it's just to tight. I guarantee this will fix the problem.
