the reason for water coming out from under the dash is that a hose could have broke or you have a problem with your heater. your heater works off of the water in the radaitor and since it gets hot from the motor well it serculates threw the heater and that's who your heater works
Heater core / hose leaking.
You probably have a puncture in your heater core.
you now get over it
coz ur momma is in ur bonnet!
not any oil in your heater core although the heater core uses coolant coming from and returning to the engine so when damaged or being worked on coolant can leak under the dash and into the floor
The gas tank, maybe? MOST LIKELY IT IS THE HEATER CORE LEAKING OR IT COULD BE WATER CONDENSATION FROM THE A/C EVAPORATOR CORE.
Look fore a hose under the dash on the passengers side or in the engine compartment fire wall, it may be plugged up or missing.
There is probably a leak in the heater core which is under the dash on the firewall.
If the noise is coming from the dash, your condensation drain is clogged. under the vehicle, passenger side at the bottom of the a/c box is a rubber "udder" reach up and squish it to open it up and drain out the water. p.s. wear a raincoat...
That means there is something wrong with the fuel injection system.
The drain for the condenser may be clogged.
fuse box will be in or under the glove box and the fuse will be blow stopping dash lights from coming on .
