Part Identifier
P02
Subject:
Replacement of the Rear Heater Blower Resistor
ATTENTION: Service Manager / Service Technician
This is to notify you of a voluntary recall campaign which involves 911 Carrera 2 and 4 vehicles of model years 1989 to 1992.
It has been determined that after the operation of a vehicle for a period of time sufficient to reach normal operating temperature, the potential exists for an electrical problem to develop in the resistor for the rear heater blower. Within a few minutes after the engine has been turned off, the rear heater blower may automatically operate in order to dissipate heat in the engine heating system. During this operation the reistor for the rear heater blower can become electrically overloaded due to a binding or seized rear heater blower.
The overloaded resistor can create heat sufficient to ignite the plastic air pipe to which it is connected, thus leading to an engine compartment fire.
A total of 11,346 cars fall within the scope of this recall. All potentially have the defect and will be recalled to have a new resistor, which has a circuit breaker, installed.
The VIN ranges of the affected vehicles in this recall are: (see illustration)
Customer Notification
Porsche Cars North America, Inc. will notify all known owners of vehicles within the recall VIN ranges directly by first class mail during the week of January 3, 1994. See enclosed copy of the recall notification card to the consumers. A listing of all vehicles with owners' names and addresses in your area, within the recall VIN ranges, will be sent to you shortly.
If a vehicle within the recall VIN ranges is in your dealership for service/repair or is in dealer inventory, the recall campaign should be performed without delay.
If the vehicle has been detailed or dealer traded, the dealer is to make the necessary arrangements to have the customer or receiving dealer contacted and the recall campaign performed.
