I parked my car for a couple days due to the storms we had up here.
So i go to jump back in when the rain stops and discover i have a pool in my passenger foot well.
I cannot see where the water is coming from.
Its mainly located smack dab in the middle of the floor.
I dont really know how to describe the location.
Its between the dash and the seat, almost 1/2 way between them.
Any guess's where the waters coming from?

 

a rotting floor pan? get underneith and see if there are any rust spots

if its antifreeze its prolly ur heater core
