    Working on a '92 Western Star. It's located behind the right dash panel near the brake valves. It's doing a fine job leaking air.

    Looks like a backyard repair gone wrong

    It doesn't look like it goes to anything, but it doesn't leak when the heater on on the "floor" position.

    A blend door then? You have air powered vent doors?

    If it goes to nowere just remove it and plug the line. A door actuator that fell from its place is probably a safe guess

    Yup.

    I didn't think this thing was related, but.....

    The blend doors do not go to the floor heater position, which happens to be the only setting where it doesn't leak.

    It's a blend door motor. I saw another one inside the dash, but it was encased in a sleeve. Might have to buy a new one. Those are rubber seals at the top that fit in a sleeve or cylinder. But I see nothing in the dash that it fits, but I did find the door that it operates.
