How to shut off the heater blower fan?

I swear as soon as I turn the key the fan in the cab starts blowing and making noise, even when my heater controlls are in the off position.

Any idea what could be causing that and a remedy for it? Please don't say pull the fuse, LOL

(I would share a pic but I don't know how to photograph noise)
