Air conditioner blows a fuse after running for 10 minutes?

I'm wondering what could be the cause. It blows a fuse even when I unplug the compressor. It basically blows a fuse every time I turn the fan motor on with the compressor unplugged. I think the fan motor is good and I checked a lot of the basic stuff I believe. I have a 67 Skylark. Thanks.

Does it do this on ALL blower speeds??? Or just high??? Most common is a bad blower motor that's drawing too much amperage.

you should be able to the fan motor rewound if necessary.

anybody who rewinds alternators / starters should be able to handle that.
