2021–2023 Bronco - HVAC Switches Out Of Recirculation Without Input
- Air Flow Mode Door Inlet Strategy
Some 2021–2023 Bronco vehicles may exhibit the HVAC switching out of recirculation without
input. This may be due to the air flow mode door inlet strategy while in recirculation mode. This
strategy periodically purges the cabin air every 30-60 minutes depending on conditions the vehicle
is operated in. If monitoring the Air Inlet Door PID with FDRS, it can go to approximately 50 %
movement of the Air Inlet Door while in recirculation mode. During this climate control system
strategy operation the recirculation button light should not go off. This is normal operation of the
climate control system and no repairs should be attempted. If the recirculation button/light goes off
then reference Workshop Manual (WSM), Section 412-00.
