Fans only work when AC is on

If you're talking your cooling fans (engine) I'm not knowledgeable enough to help. I had a problem with my AC controls and blower motor where I had no defrost, AC, or nothing period. Blacksheep pointed me in the right direction and I checked the blower motor relay under the dash. Presto, fixed it. Good luck to you. Smart folks here, someone should be along to give you a starting point.
