  1. Start the engine.
  2. Open the instrument panel compartment.
  3. Observe the recirculation actuator while pressing the recirculation switch.
Does the recirculation actuator operate?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems Go to Step 3 
3 Test the fresh/recirculation switch. There should be continuity between terminals 4 and 5 in the recirculation position (switch depressed) and between terminals 4 and 2 in the outside air position (switch not depressed).
Did the switch test OK?
Go to Step 4  Go to Step 8 
4 Test the outside air signal circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?
Go to Step 9  Go to Step 5 
5 Test the recirculation signal circuit for a short to B+. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?
Go to Step 9  Go to Step 6 
6 Inspect for poor connections at the harness connector of the recirculation actuator. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?
Go to Step 9  Go to Step 7 
7 Replace the recirculation actuator. Refer to Recirculation Actuator Replacement .
Did you complete the replacement?
Go to Step 9  -
8 Replace the recirculation switch. Refer to HVAC Control Assembly Replacement (Control Assembly)  in Stationary Windows.
Did you complete the replacement?
