70 Chevelle heater fan fuse keeps blowing out

I have a 70 Chevelle with A/C.

The heater fan fuse keeps blowing out.
Replaced ignition switch.
Replaced Fan motor.
Cleaned and checked connections to fan switch.
Fan switch is only one year old.
Last night I put a new fuse in the fuse holder.
Car was driven today without using the fan and the fuse was blown when I checked it.

Any ideas. Thanks

Replace the fuse, with fan and AC turned off, turn key on and back off, check fuse, if fuse is blown you have a short. Post back with results.
