You may have a clogged heater core, or a leak in the system somewhere. Take your car to a mechanic who can replace the heater core or diagnose the leak.

The heater core or a hose to the heater core has a leak. Hopefully it's a hose under the hood because it's a very involved process to get the heater core out.

No, it's not normal. You have a leak in the heater core or may just be connections to heater core. If left untreated, it will soak into your rug and eventually cause your floor to rot.

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

Check for a line leak to your heater core or a leak in the heater core it self. Usually it is under the dash on passinger side.

On the 1994 BMW 530i, the heater core is located under the dash in the engine compartment. You know the heater core is bad when it starts to leak.

The most common signs of a bad heater core are; no heat or fluid leaking into the passenger compartment. The heater core can have a leak or it can be plugged.

Check the heater core, it is probably bad. It could be heater hose connections to the heater core, but I would bet on the heater core going bad.

I'm not saying it can't be done successfully, but almost any procedure that truly unclogs a heater core will also cause it to leak.

There really is no way except to replace the core. In the old days you could pull the core and have it soldered up at a radiator shop, but most modern heater cores are aluminum and plastic. You can try stop leak but i have had very poor results using stop leak in heater cores.

Heater core is shot, its monted on the firewall behind center console/instrument cluster. When turning on heater fan, will dischrge coolant out of the vent. Replace heater core to resolve the leak
