NHTSA recall 93V204000
Electrical System · Porsche Cars North America, Inc.
Details
What's wrong: 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.
Why it matters: The overloaded resistor can create heat sufficient toignite the plastic air pipe to which it is connected, resulting in an enginecompartment fire.
The fix: Porsche dealers will install a new resistor containing a circuit breaker.
