I have a 1998 Lincoln Continental. I have water in the front passenger footwell. It's only wet right in front of the seat. The carpet on the firewall is dry, so I'm assuming that eliminates anythig from the engine compartment. I ran it for 4 days without using the AC, and the water is still there. The carpet along the door is dry, so I assume that elimnates any leakage from the door. I don't see any water stains around the windshield or sun roof. It's bad enough that when I removed the rubber plug in the floor below the carpet, that water dripped out. I'm at a complete loss as to where it's coming from. Any ideas?
