File In Section: 01 - HVAC

Bulletin No.: 00-01-39-002

Date: September, 2000

TECHNICAL

Subject:
Noise in HVAC System/Insufficient Air Flow From HVAC System/HVAC System Pulling/Lifting Papers/Debris From Glovebox Bin (Install Barrier Material)

Models:
2001 Oldsmobile Aurora
Built Prior to VIN Breakpoint 14123892

Condition

Some customers may comment on the following conditions when the HVAC system is in the RECIRC mode:

^ Noise in the HVAC system near the IP storage compartment (glovebox).

^ Insufficient air flow from the HVAC system or the HVAC does not operate properly.

^ Papers/debris are being pulled/lifted/drawn from the IP storage compartment (glovebox) bin.

Cause

The HVAC module, when in the RECIRC mode, may have sufficient strength to pull/lift/draw papers/debris out of the top of the IP storage compartment (glovebox) bin when the glovebox door is closed.

The ingestion of the papers/debris may cause noise, insufficient air flow and/or the HVAC module to be inoperative.
