Campaign - Air Bag, A/C Wiring Defect
A/C System Wiring or Dual Stage Airbag Module Wiring
# 05034A - (Jul 22, 2005)
Models:
2005 CHEVROLET COBALT
2005 PONTIAC PURSUIT
THIS BULLETIN IS BEING REVISED TO INCLUDE ADDITIONAL LABOR TIME IN THE EVENT THAT THE VEHICLE IS BROUGHT IN
WITH AN INOPERATIVE A/C SYSTEM. DISCARD ALL COPIES OF BULLETIN 05034 ISSUED MAY 2005.
Condition
Certain 2005 Chevrolet Cobalt and Pontiac Pursuit vehicles have one of two conditions, 1) the steering column mounted airbag module wiring may be
reversed. The driver's air bag will deploy under the same conditions (see "When Should An Air Bag Inflate?" in your owner's manual) and the vehicle
meets the occupant protection requirements of the Motor Vehicle Safety Standards. In the event of a moderate frontal impact, however, the airbag would
deploy fully instead of at the reduced level described in your owner's manual, or 2) vehicles equipped with a 2.2L engine (L61) and air conditioning
(C67), voltage spikes from abnormal fan switching can damage the air conditioning pressure sensor transducer, resulting in a loss of air conditioning.
Damage is more likely to occur if the abnormal fan switching occurs when the vehicle is being driven in city traffic and when the outside temperatures
are 70°F (21°C) or higher. The spikes can also cause the engine to operate in a reduced power mode. If this occurs, the Driver Information Center will
display "ENG PWR REDUCED", and the maximum throttle opening will permit a speed of about 30 mph (48 km/h).
Correction
Dealers are to 1) modify the circuitry to the airbag module, or 2) install wiring to isolate the voltage spike.
Vehicles Involved
Involved are certain 2005 Chevrolet Cobalt and Pontiac Pursuit vehicles built within the VIN breakpoints shown.
Important:
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) prior to beginning program repairs. [Not all vehicles within
the above breakpoints may be involved.]
For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete Vehicle Identification Number, customer name and
address data has been prepared and will be loaded to the GM DealerWorld (US) Recall Information, GMinfoNet (Canada) Recall Reports. Dealers will
not have a report available if they have no involved vehicles currently assigned.
The Campaign Initiation Detail Report 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
Parts required to complete this program are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved
vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order.
In an emergency situation, parts should be ordered on a CSO = Customer Special Order.
Service Procedure
