Compressor relay

Just less than year ago, dealer replaced all my A/C parts except compressor. Now A/C out again, refrigerant level fine per local mechanic, but no variation from baseline pressures when start A/C, which just blows warm air. Mechanic thinks compressor not working. Before I go to dealer, would like to check relay to compressor isn't bad. Can anyone tell me what it's labeled on diagram under lid of fuse box/relay compartment, or better yet, send picture of that compartment with arrow drawn to the correct relay?

Thanks, Lew
