THIS BULLETIN IS BEING REVISED TO ADD MODELS AND ALL YEARS. THIS BULLETIN CANCELS AND REPLACES BULLETIN 88-1-26 ISSUED 7/92.
In 1991 a new HVAC blower motor and press-on fan impeller were released into service for both past and present Pontiac vehicles. Since these new parts were not able to be retrofitted to the old "bolt-on" style components, replacement of either the fan or motor required ordering both parts and hand assembling prior to use.
To eliminate the need for hand assembly, which does not allow for proper balancing, a pre-balanced press-on motor kit is now available as a service assembly.
The motor used in this assembly has been revised to include an air shield to protect the motor from ingesting dirt and oil which could lead to intermittent operation or failure of the motor. At this time this enhanced blower motor is only available in the press-on motor kit.
When replacing either the fan impeller or the blower motor use the chart for the correct replacement kit.
* Check failed part for part number stamp and refer to chart for appropriate replacement.
For service procedure refer to Section 1B or 1C of the appropriate Service Information Manual.
For front wheel drive vehicles, it may be necessary to rock the engine slightly to allow access to replace the fan motor and impeller as an assembly.
To provide this access use the following procedure:
1. Remove two cradle bolts from front of vehicle. See section on frame in the appropriate Service Information Manual.
2. Slightly raise vehicle to allow engine to rock forward and give access to blower motor assembly.
3. Disconnect electrical connector and cooling tube to blower assembly.
4. Remove five screws and blower assembly.
5. Replace fan motor and mounting screws.
6. Lower vehicle.
7. Install two front cradle bolts and torque to specifications indicated in the appropriate Service Information Manual.
Parts are currently available from GMSPO.
