Chevrolet had issued a bulletin for the A/C problem. Was your system reprogrammed under the same bulletin? If it was, hopefully it was done correctly...
Here is a copy:
Bulletin No.: 11160A
Date: May 31, 2011
Subject: 11160A - Loss of Air Conditioning - Reprogram Body Control Module
Models:
2011 Chevrolet Camaro Supercede:
The service procedure in this bulletin has been revised. Please review Steps 3 through 9. Please discard all copies of bulletin 11160, issued May 2011. THIS PROGRAM IS IN EFFECT UNTIL MAY 31, 2013
Condition
Certain 2011 model year Chevrolet Camaro vehicles may have a condition in which the air conditioning compressor may not turn on or turn off. This could cause the compressor to fail, resulting in a loss of air conditioning.
Correction
Dealers are to reprogram the Body Control Module.
Vehicles Involved
Involved are
certain 2011 model year Chevrolet Camaro vehicles.
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Required Field Actions section in the Global Warranty Management system. Not all vehicles may be involved. For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.
Parts Information
No parts are required for this program.
Service Procedure
Do not attempt to order the calibration number from GM Customer Care and Aftersales. The calibration numbers required for this service procedure are programmed into Control Module via a Multiple Diagnostic Interface (MDI) with the calibration update. When using a MDI for reprogramming, ensure that is updated with the latest software version. Use
TIS2WEB on or after 05/16/11 to obtain the calibration. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
For step-by-step programming instructions, please refer to SI and the Techline Information System (TIS) terminal.
1. Verify that there is a battery charge of 12 to 15 volts. The battery must be able to maintain a charge during programming. Only use an approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery voltage during programming. 2. Reprogram the body control module (BCM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required. 1. Connect the MDI to the vehicle. 2. Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen. 3. Select BCM Body Control Module -- Programming from the Supported Controllers screen. 4. Follow the on-screen instructions. 3. On the SPS Supported Controllers screen, select BCM Body Control Module - Setup and follow the on-screen instructions. 4. Remove the MDI and turn the ignition off. 5. Open and close the driver's door. 6. Wait 2 minutes. This will clear the Stabilitrak message if present. 7. Clear all diagnostic trouble codes (DTCs). 8. If the vehicle is equipped with a sunroof, close the sunroof completely and re-open the sunroof to the full-open position. 9. Check the driver information center display for additional messages regarding further calibration instructions. If there are no additional driver information center instructions present, programming is complete.
