    Your issues aside, you are correct lol. This is why I typically run the blower on anything but high in whatever I'm driving, unless I'm trying to defog the windshield.

    1987-1996 F series trucks are just as easy, if not easier to do. Remove the glove box door and you can change one in less than 30 minutes. This is coming from a guy who easily spends 3x the amount of time to do something compared to the next guy.

    Heater core is not obstructed by leaves, and air plenum design is such that no foam is needed, air cannot move past it. There are foam pieces at the top and bottom but the sides don't use any.

    Upon closer inspection, some disassembly, and some head-scratching, I realized that there is no recirculate function. The lever labeled "outside air" is in fact the "air on/off" flap, and if it is closed, there is no air source for the blower to suck in. So that would be why 1. the air speed drops considerably when it is closed and 2. the blower vacuum seems to be able to pull it open on higher speeds.

    I found the (plastic) wall behind the flap that faces the interior and drilled a bunch of holes, so now when the air flap is closed, it does actually recirculate air from the passenger footwell. It basically works like a Panther recirc door now instead of a Ranger dumbass outside air flap. On higher fan speeds it still pulls the flap open partially but that's fine, at least recirculation can actually happen now. Test drive yielded excellent heat with the door in the recirc position so it seems likely that all my heat issues just come back to it being well below freezing outside, probably plus a coolant flow factor, e.g. super cold air comes in, almost all of the available heat currently in the heater core is transferred to the air, leaving no more available, and coolant flow is maybe too slow to sustain the heater core temperature.

    If I were to take a guess, A/C equipped models probably have a recirculate vent in exactly the spot I drilled the holes.
