If the belt started spinning fine once you shut off the AC on the dash...then it's the compressor is locked up. Looks like you need a new AC compressor.

Or throw a NON A/Ced belt on your 12V and leave the non working AC unit right there.
It all depends on how important having A/C is in your work truck.
I have a spare old NON A/C belt sitting in the back seat of my A/Ced 12Vs for that very reason.
