When I turn on the feet heating mode (the arrow on the display pointing at feet), I don't feel any hot air blowing at my feet. It blows hot air in the other modes though (face, windshield). I don't feel hot air in the feet in either of the front 2 seats. I feel like I remember years ago when I used the heater, the hot air used to blow at the feet.

Today I was cleaning the blower fan, and when I was taking out the glovebox I did not see any vents that blow air at the feet. How does the feet heating feature even work? And why isn't it working for me anymore? Does that feature even exist or am I missing something?

UPDATE:
Did some testing with the climate controls set to ECON. When the arrow points at feet ONLY, the blower is spinning max speed but hot air only comes out of the windshield vents, and none from the feet.

 

Do a search here on this... There's probably 100 threads about this symptom. Usually an actuator that moves the levers to place the air output where it's needed.

Download the service manual and do the heating system diagnosis check built into the electronic climate control system. The instructions will most likely net you a confirmation the actuator has failked

Go to Section HA (HA.pdf)

Depending on if you’ve got an auto or manual heat and AC system, run the system tests or self-tests as appropriate.

Based on what you’ve described, you’ve got a ‘mode door’ issue, which is addressed in the HA section of the FSM.

 

Thank you! I checked by the gas pedal... a lever disconnected from the foot mode door, all I had to do was connected it back, took 5 seconds!

 

Could you please take a pic of the lever you are talking about? I am facing the same issue
