Duster Heat?????

Like I mentioned above, it took two tries before the heat would remain working. You can see the goop that came out on the first pass.

The second time I rigged this arrangement so I could run water through it for an extended time without having to stand there and hold it.

Pay careful attention to the output and input of the heater core. Inflow is normally the hose closest to the center of the car, so push water the opposite direction to reverse flush it.
