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.
  1. Disconnect air recirculation stepping motor 2-pin connector. Turn ignition on. Connect a Red/Green LED test light between stepping motor harness connector terminals No. 1 (Red wire) and No. 2 (Yellow wire). See WIRING DIAGRAMS  . Press ACC control panel air recirculation button on and off several times to activate air recirculation damper stepping motor. If Red and Green LEDs alternately illuminate as air recirculation is switched between outside air and recirculated air, replace air recirculation damper motor. If both Red and Green LEDs do not alternately illuminate, repair Yellow wire or Red wire. When repairs are completed, go to next step.
  2. If no new DTCs are detected, repair is complete. 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.
