I have a 2005 v6 mustang. I was approaching a stop sign on a hill the other day and water poured from under my glove box. Is this the heater core? If so, how much of a pain is it to change? (other than just taking the dash out)
If it was a heater core the liquid would be antifreeze. Very distinct smell and texture not easily mistaken for water.
It could be the well known water leak, or your cowl drains are clogged with leaf debris. Clogged drains would allow water to slosh around in the tray and enter thru the cabin filter or someplace else in the cowl.

There also is an condensate drain in the engine compartment, under the battery tray on the fire wall. If plugged it will allow water to build up inside the heater core box.

welcome to the forums. there is also a large rubber grommit that passes through the body in frt of the passenger foot area. you have to pull the inner wheel well to check it.( which i did and you should too just to make sure its seated) but it sounds like the previous poster hit it with the cowl area, sloshing around the cabin filter, the drains are plugged. you would have a constant coolant smell if the heater core was leaking.
