Sorry, I can't find a wiring diagram for your car showing numbered terminals on the CCRM. According to the post I gave you, 22 and 15 are for the coil of the relay and 21, 23 are the contacts, meaning one of them is 12volts with the ac switch turned on and the other goes to the ac clutch. Measuring across 21, 23 will not give you a reading, you have to go individually to ground. Also to test the relay, put your voltmeter + on 22 and - on 15. If it's showing 12 volts, and the relay is not operating it's bad.
