The stupidest questions are those that aren't asked though.
Should the Air con relay "click" audibly when the "AC" button is pushed, while the HVAC is on and blowing air and set to 18 degrees Celsius? Regardless of all other factors such as pressure in the system and engine running? If I'm reading the wiring diagram correctly then the answer should be yes.
Mine doesn't and hasn't blown cold air (read, compressor never engaged) since I've owned it.
If I test the relay with a multimeter, the two pins on the human/button side have continuity (although quite high resistance but that may be because of the coil inside) and the and the compressor side pins are open. I haven't had a chance to directly apply power to it because I don't have test leads or alligator clips to get into the tight space
Edit: yes I've checked the fuse.
Edit 2: the AC light turns on
