I'm working on a 2015 Chevy duallie with a school bus body on it and the turn signals don't work but the hazards work fine, lights are good, can't figure out where the turn signal relay is at

Hi there, I am Cam. Can I get your first name please?

These do not use a stand alone relay, rather the Body Control Module (BCM) puts the power out directly. There are a couple fuses not very well labeled for the lights. They are fuses F26 (10 amp), Fuse 7 (10 amp) and fuse F72( 10 amp) all in the underhood fuse block. These are what the Body Control Module (BCM) uses for power to run the lights. Can you check these fuse please?
