Porsche 911 and 1 more
The defect
After the engine has been turned off, the rear heater will automatically operate in order to dissipate heat in the engine heating system. During this operation, the resistor for the rear heater blower can become overloaded due to a binding or seized rear heater blower.
The risk
The overloaded resistor can create heat sufficient toignite the plastic air pipe to which it IS connected, resulting in an enginecompartment fire.
The remedy
Porsche dealers will install a new resistor containing a circuit breaker.
