Heater fuse?

My heater fan (I don't have A/C) blows all the time even though the system is turned off. I want to pull the fuse until I get time to figure out what is wrong. Which fuse do I pull?

My truck is a 1973 K20

Re: Heater fuse?

Is it blowing on HIGH?

Don't know if it's the same, but on our 86' C30, the high speed for the blower comes in from under the hood and feeds a relay. No fuse for it - well there is a fusible link.

Can you just pull the connector at the blower?
