What could be the problem? I put 10-amp 15 amp and 25 amp the only one that didn’t blow is 25 amp, but clutch not engaging?

This happens when the A/C compressor coil is shorted out, which is a common repair on all cars. I would get a new compressor from Amazon (AC Delco unit). here are generic guides to help you do the job with specific instructions in the diagrams below for your car:

There is only one wire (brn-grn) from the compressor clutch and the relay, it could be the relay is shorted out because of the bad compressor. here is a guide to help check it and the location of the relay #62:

So, you're saying my A/C relay needs to be replaced, and that could be causing my A/C clutch fuse to burn out?

The only thing left is the wiring, it must be pinched or rubbed through. Please use the guide and wiring diagrams to test the brown/green wire, make sure it is not shorting to ground.

I had to run a wire to compressor to battery to over pass it but it’s working that way. Thank you so much for advice and help. I highly appreciate it.
