Heater/AC vent issues

[brown baron]

Does anyone run into the issue of having barely any air coming out of the vents when the footwell vents and middle vents are on at the same time?

There's a ton of air flow when only one of them are one

a/f definitely goes down a little but setting 4 or 5 of the fan speed is plenty for mine.

Same here, can hardly feel it when its split between the floor or windshield, even when its set at 7.

If mine is set at dash and defrost set on four it hardly blows. Ford put seven speeds on these trucks, and they need to re-engineer the power. I was happy to get more fan settings. Just to find out they do not blow with much power if divided. I would like to see more power when we choose two settings. I think we need a dial that we control the fan speed, maybe a variable. Not sure if that's a proper term for it.
