Do you know what kind it is? They usually have a small black switch on the side of the Light Kit or where the light would be if it doesn’t have one. If it is modern enough to have a remote, it has a reverse switch. But if you can feel air come down, I’m pretty sure it’s not reversed. Does it have pull chains? or where it looks like it might have had one. Possibly it’s been pulled off and in that case you can purchase the pull chain switch at a home depot.
