DEALER ACTION
To prevent this condition from occurring on involved vehicles, dealers are to replace Electronic Comfort Control Assembly.
As remanufactured Control Assemblies will most likely be the repair parts used, dealers are reminded of their obligation to advise the vehicle owner when such parts are used.
Dealers are to perform this campaign on all vehicles involved at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory or it is in your dealership for service, dealers are to ensure the campaign correction has been made before selling or releasing the vehicle.
Dealers are to contact owners of vehicles recently sold from your new vehicle inventory and arrange for the campaign correction to be performed.

SERVICE PROCEDURE
1. Record the station settings on the radio, then remove fuse # 2, "ELEC" (15 amp.).
2. Remove the instrument panel trim plate at the air conditioning Control Assembly.
3. Remove and set aside the screws which secure the Control Assembly to the instrument panel.
4. Remove the Control Assembly from the instrument panel.
5. Inspect the top of the Control Assembly for the part number and the date code as shown in Figure 1.
For a part number of 16050293 or 16050303: If the date code is "11 02 8" (Nov. 2, 1988) or later, proceed with Step (9) to REINSTALL the Control Assembly. If the date code is earlier than "11 02 8", proceed to Step (6).
If the part number is 16138023 or 16138033, proceed with Step (9), to REINSTALL the Control Assembly.
If the Control Assembly has a Delco remanufacturing label, "FACTORY AUTHORIZED REMANUFACTURED MODULE", proceed with Step (9) to REINSTALL the Control Assembly.
6. On the rear of the control assembly, disconnect the electrical connectors.
7. Determine which air conditioning Control Assembly is installed on the vehicle and obtain a new assembly for installation:
With rear window defogging (RPO C49) - P/N 1228880.
Without rear window defogging - P/N 1228881.
Inspect the labels on top of the NEW Control Assembly to ASSURE that it meets the requirements of Step (5). If the Control Assembly is a P/N 16050293 or 16050303 with a date code earlier than "11 02 8", return the part to GMSPO under their regular exchange program (See GMSPO bulletin 89-8).
