So, I'm driving my '73 911 in the rain last night and the wipers stop. I replace the fuse, the wipers move slightly, and the fuse blows again. Now the fuse blows as soon as I turn the ignition key--before the wipers move and regardless of switch position (off, low, medium, or high speed).

I have removed the wiper motor from the wiper arm assembly to make sure the motor was not overloaded--nothing. I have also inspected the wires at the switch, motor, and fuse box, and do not see any loose connections or worn sheathing that might cause a short. The fuse is the right amperage (25A), and the wipers have worked perfectly until now. All other electrical components are working fine (except for the rear defrost, which didn't work before). I don't see any burnt or blackened areas near the motor or switch.

Any ideas? If you think you can help me, please talk (or post) slowly and simply--I am an electrical moron. It's winter in Oregon, which means I need my wipers. Thanks in advance for any suggestions.
