When all else has failed, it's possible that your heater core is bad. If this is the case, we're sorry. Replacing a heater core is not typically an easy task on a BMW, but we're here to support you with the quality OE aftermarket and Genuine BMW replacement parts that you need to service your vehicle correctly.
Brand new heater core from OEM Nissens! The heater radiator uses a hot engine coolant passing through the core to create heat to warm the cabin. The blower motor moves this heated air into the interior of the car. If a heater core develops a crack or leak, it is likely that moisture will condense on the inside of the windows and the smell of anti-freeze may be apparent.
