Sorry that my information got deleted. What I would do is remove the relay, then jump terminals 30 and 87 with a stretched-out paper clip. There's no easier way to turn the circuit on. Now measure the voltage on the paper clip with the compressor plugged in. If you have 12 volts, the cause of the problem is further down the circuit. If you don't have 12 volts, check on both sides of the fuse.
Connector C102 is the next good test point. That's also a good place to find a stretched or corroded terminal. Test on both sides of the connector.
