Default 03 a4 b6 1.8t. cooling Fans will not come on

I have replaced the FCM. I hardwired the fans and they work. But will not come on under its own power. I checked the relays under the ECU and they look fine. I need help

FCM burnt up. I have replaced the FCM. I hardwired the fans and they work, ran straight power to the FCM harness and fans worked. When I connect at the harness my fans do nothing. Two relays are next option I think. #219 #395
