Simple fix, you need a flasher. Its not on the fuse panel it will be tucked up under the dash somewhere, could be harder to find. The flasher on the fuse panel is for your hazards, a different flasher circuit than your turns. Find the other flasher and replace with any similar 12v flasher at the auto store. Your turn flasher will have a blue and a purple wire going to its connector.
...some cars may have the turn flasher wired to the fuse panel, if thats the case you will see two flashers on the panel itself. If you don't see two flashers there start looking under and in back of the dash to find the other one. Other cars will have the turn signal flasher in the fuse panel and the hazard tucked under the dash, I'm assuming you already checked the flasher on the fuse panel and no luck.
