Ac, heated seats and steering wheel stopped working all at once
 

2014 Cadillac SRX
Hello , first time on here so forgive me if I seem new . So basically car ac was working fine , I switched from face blower to feet and face blower , then back to face and ac stopped working. Also heated seats and heated steering wheel won’t heat up now. I don’t know what happened. I did what I know and checked all three fuse boxes and looked for anything ac related, but found no blown fuses. Only thing i can think of is something behind the radio cluster. Anyone have this problem before ???

Test relays and clean them
