    I’m a little confused. I always felt like my a/c position for feet only didn’t push much air. I figured cause it’s send air to the rear and passenger ducts. I’m always the only person in my car so I decided to tape up the tear ducts and passenger ducts for the feet and stil does t seem to make a difference. In fact. What I did notice was… the best air flow I got on my feet position was when I have the setting on front and feet ducts. Significantly more airflow to feet.
    What am I missing or is everything as it should be
    Thanks

    could be a problem with the vent doors. turn the fan on high, make sure the filter is clean or remove it.

    set the direction to face, then change it to floor while your hand is at the floor vent and see how much air comes out, and how the upper is reduced.
    check the passenger side as well

    You should have a button on your HVAC controls that restricts air to the rear (shuts off rear floor vents and reduces fan speed to the upper vents) when the green LED is lit; so, you don't need to tape off the rear floor vents. The graphic shows a boldened front passenger and a grayed out rear passenger, I think. The HVAC is even smart enough to reduce air to the front passenger side when the seat is unoccupied! And, yes you get better heated airflow by overriding the flow settings to upper+footwell instead of just footwell vents. You can also override the fan setting, of course, to push more air.
