Diagnostic Procedure

WARNING: This page is about a different car, the 2001 Saab 9-3 and 2000 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

Replace ACC control module with a known good ACC control module. Using scan tool, clear all DTCs from all systems. Recheck A/C system operation for original complaint. If A/C system is operating properly and no DTC has been detected, repair is complete. If a DTC has been detected, a control module may need to be replaced. See CONTROL MODULES  under COMPONENT TESTS.
