Models: 2004-2005 Buick Rainier 2002-2005 Chevrolet TrailBlazer Models 2002-2005 GMC Envoy Models 2002-2004 Oldsmobile Bravada 2005 Saab 9-7X Condition Some customers may comment on slow to cool Air Conditioning (A/C) performance or high A/C outlet temperatures after start up or that the A/C system is not cooling sufficiently, especially in high ambient temperatures. This may be an intermittent condition and the performance of the Heating, Ventilation and Air Conditioning (HVAC) system may not meet customer expectations. Cause This condition may be caused by the response of the Electro-Viscous (EV) fan clutch and can be related to airflow across the condenser. This low A/C system performance can occur for longer periods of time if the vehicle is allowed to idle or is driven in low speed conditions. The response of the EV fan clutch will affect A/C system performance. As higher road speeds are attained, the increased airflow across the condenser will usually improve A/C system performance and the response of the EV fan clutch. This condition may be more evident after the vehicle has set for a period of time and can be difficult to duplicate. The condition may occur after the vehicle has set for as little as 10 minutes or as long as overnight. It is most prevalent intermittently during the first 15 minutes of operation.

This connector is not sealed from the inside of the vehicle and water may enter the connector causing the terminals to become corroded. Also, the female terminals of the connector may have become spread apart causing an intermittent poor connection. Correction Important: • Inspect the terminals at connector C305 for corrosion or spreading before replacing the fuel module or resistor card kit. Terminals can be accessed from underneath the vehicle. • Do not attempt to repair any spread female terminals as this will result in a return repair. The female terminal must be replaced. • If the terminals show signs of corrosion, determine the source of the water leak first and repair the water leak before repairing the terminals in connector C305. Refer to Corporate Service Bulletin Number 01-01-38-009A to determine a potential source for water in the vehicle interior. Repair any corroded and/or spread female terminals in connector C305. Refer to Repairing Connector Terminals in the Wiring Systems sub-section of the appropriate service information.

The purpose of this test is to satisfy the enable criteria necessary to execute I/M readiness diagnostics for the evaporative emission (EVAP) system. The test may be used to set the I/M System Status indicators to YES. Service Bay Tests are included on the scan tool for some systems depending upon vehicle make and model. The test is designed to allow the EVAP Diagnostic Tests to run in service bay conditions. Ensure that the vehicle meets the requirements listed in Conditions for Running before performing either EVAP System Test. Failure to meet the necessary requirements may produce inaccurate test results. CONDITIONS FOR RUNNING Non Scan Tool Service Bay Test equipped vehicles ^ The barometric pressure (BARO) is more than 75 kPa. ^ The fuel level is between 15-18 percent. ^ The battery voltage is between 10-18 volts. ^ The test will initiate only after a cold start. The control module considers the engine to be cold if the following conditions are met: – The engine coolant temperature (ECT) is between 4-30°C (39-86°F). – The intake air temperature (IAT) is between 4-30°C (39-86°F). – The difference between the ECT and the IAT is less than 8°C (14°F). Scan Tool Service Bay Test equipped vehicles ^ The BARO is more than 75 kPa. ^ The ECT is less than 70°C (158°F). ^ The fuel level is between 15-18 percent. ^ The battery voltage is between 9-18 volts.
