CONDITION: Field reports indicate the vehicle air conditioning system uses only outside air, even if the recirculation mode is engaged or the recirculation mode doesn鈥檛 operate at all.
CAUSE: It is most likely that the vehicle cabin air filter was replaced with the air blend door in the 鈥楩resh Mode鈥 or the blower assembly door was moved manually, damaging the door shaft or the servo motor located on the blower assembly.
CORRECTION: To prevent possible damage to the vehicle A/C system, verify the air blend door is set to 鈥楻ecirculation Mode鈥 prior to servicing the vehicle cabin air filter. The proper procedures are listed in both the vehicle service or owner鈥檚 manual.
