How do you change cooling fans on 03 cobra
 

I have a 2003 Cobra with 13,000 miles. The cooling fans stopped working and the car overheats. I checked the fuse and it was bad so I replaced it. As soon as I turned it on it blew the fuse. I tried to turn the fan blades by hand and they won't move. I assume I need to change the fans. Is it hard to do? How do you do it?

Thanks,
David
