Bluedriver doesn't address it try this- it worked for my 2008 9C3 DORMAN BLEND DOOR 604-108 $12.99 Recalibration instructions: 1. Disconnect negative battery cable 2. Turn ignition on- engine off 3. Wait 5 minutes 4. Turn off ignition (remove key) 5. Reconnect battery cable 6. Insert key and turn ignition on- engine off 7. Wait 5 minutes- do not adjust HVAC controls 8. Done-start car and observe if door operates with circulate/recirc this
Just my two cents, this worked perfectly on my 2008 Impala...
