Model:
2005 CHEVROLET COBALT
2005 PONTIAC PURSUIT
EQUIPPED WITH A 2.2L ENGINE (L61) AND AIR CONDITIONING (C67)
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 05046 ISSUED MAY 2005.
Condition
On certain 2005 Chevrolet Cobalt and Pontiac Pursuit 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).
In addition, the steering column mounted airbag module wiring is reversed on these vehicles. The driver's air bag will deploy under the same conditions
(see "When Should An Air Bag Inflate?" in your owners 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 will deploy fully instead of at the reduced level described in your
owner's manual
Correction
Dealers are to install wiring to isolate the voltage spike and modify the circuitry to the airbag module.
Vehicles Involved
Involved are certain 2005 Chevrolet Cobalt and Pontiac Pursuit vehicles equipped with a 2.2L engine (L61) and air conditioning (C67), and 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
Important:
An initial supply of harnesses required to complete this recall will be preshipped to involved dealers of record. This pre-shipment is scheduled to
begin the week of May 2, 2005, and will be approximately 10% of each dealer's involved vehicles. Preshipped parts will be charged to dealer's open
parts account.
