This bulletin is being revised to update the references to the service procedures in SI and add warranty and parts information. Please discard Corporate Bulletin Number 05-01-38-001 (Section 01 - HVAC).

The purpose of this service bulletin is to announce the release of a new essential tool to service the Heating, Ventilation and Air Conditioning (HVAC) Mode Door Actuator. The new tool is an HVAC Puller, special tool number GE-47676, which was shipped in the Fall of 2004 to all Chevrolet and GMC dealers. It will no longer be necessary to replace the entire Mode Door Cam Assembly when only the Mode Door Actuator requires replacement. Previous to the release of this tool, it was necessary to remove the entire Instrument Panel Carrier to replace the Mode Door Cam Assembly. Now the Mode Door Actuator can be serviced from underneath the left side of the Instrument Panel Carrier using this new special tool.

The service procedures in SI have been updated to include the use of this new special tool. To replace the entire Mode Door Cam Assembly refer to the Mode Cam Replacement procedure in SI for more information (Document ID # 1618104). To replace just the Mode Door Actuator, refer to the Mode Actuator Replacement procedure in SI for more information (Document ID # 1609154). The labor time associated with labor operation D1808 has been changed to reflect the time savings when this new special tool is used. Labor operation D1829 has been added to the labor time guide to be used if the entire Mode Door Cam Assembly is replaced.
