water leeking on passanger side floor

[Thelgord]

Turn on your heater, any fan speed other than off. If you see water leaking, it is your heater core. If it is indeed a seal to the exterior, they may still be in good shape on the surface, but the adhesive used may have gone bad. Tracing water intrusion is a real PITA. It could be leaking higher up the windshield and working its way to a lower point on the inside. There are a lot of variable to look at.
