Typically relays draw a minimum amount of current to hold the contacts together while energized. I have never seen a relay coil short ciruit that would cause alot of current to flow and therefore blow a fuse. Most common failure with a relay is the actual contacts or less likely the energizing coil goes open circuit and no current flows to energize the contacts. If your suspect your particular relay is electronic rather than electro-machanical then its possible but unlikely as it too would more likely by design go open circuit.
See if there is an identical relay from another circuit in teh fuse box, try it, and then see if the fuse blows again. If it does its not the relay. Then put the supsect relay in the other location and test.
