A/C Control Head Recirculation Programming Service

The recirculation control is programmed to cancel the recirculation mode when the ignition is turned OFF and will reset to fresh/outside air when the ignition key is turned ON. The frequent use of outside air will help keep odors from building up within the air conditioning-heater housing. It is recommended that the recirculation mode be used as little as possible, especially in humid climates. For hot and dry climates or for people who are allergic to pollens and find the frequent use of the recirculation mode necessary, the recirculation control can be reset to Fresh/ outside mode by the following procedure.
1. Turn the ignition key to the OFF position.
2. Turn the blower switch to any position except OFF or LOW.
3. Set the mode control to the PANEL-FACE mode.
4. Depress and hold-in the recirculation button.
5. Continue to hold-in the recirculation button, and start the engine.
6. The recirculation indicator light remains lit when the recirculation button is released. The mode Will not reset when the engine is started. If the recirculation indicator light went out when the recirculation button was released, the recirculation mode reset to fresh/outside air mode when the engine is started.

The programming procedures can be repeated to change back and forth between the automatic reset and then maintain selection preference.
