I purchased a 2013 Toyota Camry with 46000 miles and I have noticed that I am not able to turn off face fan OFF. See the below picture. Fan is set to OFF but still face fan light is ON. I cannot turn it OFF.

  • Car ignition ON, Stationary and fan knob is in OFF position -- It is not blowing air.

  • Car ignition ON and moving on the road and fan knob is in OFF position -- It is blowing hot or cold air towards my face based on the temperature control knob setting.

  • With the car stationary, is air coming out of the vents towards your face? In this model, one of the four "directional" LEDs might always be illuminated, even when the fan is not running. – DavidSupportsMonica Sep 29 at 1:43
  • @David yes, it blows little air towards my face even when fan knob is in OFF position. – javanoob Sep 29 at 1:55
  • And the car is stationary, that is, not moving over the roadway? – DavidSupportsMonica Sep 29 at 2:17
  • @David I just sat in the car, while car ignition turned ON and stationary and it is not blowing air. It is blowing air only when it is moving. – javanoob Sep 29 at 2:33

    When the car moves, air outside the car is gathered in the higher-pressure area in front of the windshield, passes down through the air ducts, and is pushed into the passenger compartment without help from the fan. – DavidSupportsMonica Sep 29 at 2:38

Short answer: the fan isn't running, and the heating/AC system is operating as designed.

Long answer: you've confirmed that air only comes out of the vents when the car is moving forward over the ground; with the car standing still, no air moves. That demonstrates that the fan is not running, even 'though the LED over the air-distribution button is illuminated.

Air emerges from the dash vents because the car movement forward increases air pressure at the base of the windshield, which forces air down through the air ducts and into the interior. If a different air-distribution button were pushed, the air would emerge from whatever other ducts were selected. This air movement is independent of the heater fan.

It appears that the system is designed so that one of the four distribution LEDs is always on, reflecting the states of the various inside-the-system duct doors and blend flaps.

Note too that if the recirculation button is depressed, the car will continue to allow a small amount of outside air to enter the interior. That's designed-in behavior, common to all cars, to make sure there's some air change in the interior.
