My 2004  KIA sorento aircondionting isn't working but my heater works and the blower works. People are saying its my relay switch to compresser but I don't believe there is one on there can't find it anywhere on auto part sites. I need help!

Why do they its a relay? Did they put an electrical voltage tester on it. Could also be a leak. Best way to check is put the ac baines on it, see if it leaks down.
