Most common failure is the A/C Compressor magnetic clutch coil, when they get a little age on them the field coil start to overheat eventually shorting out. To verify unplug the A/C clutch coil and install another fuse and turn it on, if the fuse doesn't blow you found your problem, if it does then you have a short elsewhere in the A/C system.
