Let's start with jumping the relay to see if the compressor comes on. This is a magnetic clutch compressor so I would assume it should be able to spin freely.
However, if jumping power to it does not cause it to come on then I would think it is locked up since it doesn't spin as well.
Let me know if you jump pin 5 to 3 on the relay or just jump 12 volts to the compressor.
