They may be on the same fuse, but I don't think so. There is usally a fuse dedicated to the blower, because it is a high-amp accessory. If you can access the connections for the blower under the hood, pull them off and make sure they are not corroded or loose. Possible the dash control has gone south, but if it is indicating blower speed, I wouldn't think so. Turn it on high and give the housing a good whack. Sometimes the motor will get caught on a dead spot in the windings if it is starting to go bad.
