Yes, this could be a faulty fan relay, typically if you have a blown fuse, it may be due to the relay.

I would check the fuse first. If the fuse is good you can try disconnecting the connector at the fan and checking for power. If you're not sure how to do this you may be better off having a technician check it out.
