Q: I have a water leak in the passenger floor

asked by on

I'm having problems with unknown leak that only comes from the passenger side and soaks the carpet? Does anyone know what plug I have to drain or if this is major issue.

My car has 136000 miles.
My car has an automatic transmission.

This is likely a failing heater core problem. As you may know, the heater core is a unit that circulates hot coolant through a radiator like component that uses this to create heat when you turn your heater on. The leaking on the floor is most likely a result of a leak in your heater core hose. I would suggest having a professional from YourMechanic come to your location to diagnose and repair this.
