Air conditioning fuse in a non A/C truck

Is the air conditioning fuse used for anything in a non A/C truck?

The blower switch in my 69 GMC is not getting any power. The Heat fuse is good.

Well it must do something for the heater as well.

I replaced the A/C fuse and I had power to my heater switch.

THe heater motor ran, and at different speeds, but was very noisy and then the fuse blew again.....

Enough for tonight. Tomorrow I research how to change the blower motor!

yup, probably something wrong with the blower motor, and it wouldn't hurt to change the resistor as well.
