RECIRCULATION Programming

Recirculation function of HVAC control module automatically returns to outside air setting as the default setting, after an ignition cycle. This is done to prevent odors from building up in HVAC heater housing. It is recommended that the recirculation mode be used as little as possible in humid climates to prevent odors from forming.

For hot and dry climates, for people that are allergic to pollen in the outside air, or drivers that find it necessary to frequently use the recirculation mode, the HVAC can be programmed to default to recirculation mode at the end of an ignition cycle by performing the following procedure:

1. Start the engine. Turn front blower motor switch to any ON position. Set mode controls to appropriate symbol for panel/face airflow mode.
2. Turn ignition switch to OFF position. Depress and hold RECIRC button. Start the engine, and continue to hold RECIRC button while observing RECIRC button indicator light. The RECIRC button indicator light will flash repeatedly. When RECIRC button indicator light stops flashing, release RECIRC button and programming is complete.
3. Turn engine off. Wait 10 seconds, then restart engine. Verify the recirculation mode default setting is properly programmed. Repeat this procedure to select between recirculation mode default and outside air mode default settings.
