Re: 1967 Chevelle Origianl Fuse Box Issues
The A/C probably doesn't connect thru the fuse block. The blower will, but it gets power from the harness, not the accessory sockets.
Clean up the clips in the fuse block (steel wool is pretty good), put new fuses in it and see what does or does not work. Another post here will get heaps of help is something is amiss.
The assembly manual is NOT the same thing as the repair manual. The assembly manual is what Chevy used to build the cars when they were new. If you are going to be working on it, particularly if you are going to be working on wiring or trying to figure out how something was done originally, get one. It's worth it's weight in gold.
