I’ve only ever owned 3 vehicles but even the cars I’ve borrowed or rented the feet heat always sucks it just blows it straight forward back into the engine rather than down at my feet, I always have to shove my feet directly up into the dash to get heat, is there a reason we can’t adjust the feet vent or any other solution?
The BMW e30 is the only vehicle I know of where each vent could be adjusted individually. Not just on/off but you could actually balance the flow for each output to however your wanted. It was one of my favorite features of that car. In the winter time, starting cold and as the car warmed up you could gradually redirect the heat to areas where it was needed: start with full defrost, then 50/50 feet heat/defrost, and then once fully warmed up I would dial in just a little bit of the dash vents to keep my hands warm, but not so much as to dry out my eyes, and still have a bit of heat on the feet and defroster to keep the ambient temp even. You get to have it all balanced exactly however is most comfortable. That car also is the oldest one I know of which had heater vents for rear passenger feet, something I wish I had in cold winters as a child.
