Blower motor wont turn off

[AuroraGirl]

It runs constantly in my 83 k10 with an 85 interior harness. The off position is slower than Low, but it still runs. I only drive my truck in the summer so I just unplugged the harness from the blower resistor on the firewall. If I ever want heat a couple minutes plugging it back in is all it takes.

Prob have a bad relay or something
1982 the feature to turn off the fan came out.

The way I'm reading that seems to mesh with what I said. Power ventilation seems to say that there is some blower movement. Or maybe not. Marketing speak is never straight forward. I'm curious if anyone else experience matches mine. All I know is it is a lot cooler in the cab with it unplugged. I can't move my deflector valve in the heater box because I tried to replace the foam inside it with cheap crap. The adhesive came off just enough for it to block the blend door and now it won't move. And taking it off to fix it when I don't really use it is such a pain.
