Locate the blower motor, (I could tell you where it is, but you haven't mentioned what kind of vehicle you have or the year), turn on the ignition, put the fan switch, (located on your dash), on high. Tap the blower motor with a hammer. If it comes on, that will tell you that the blower motor is bad.
If that test is inconclusive, you would need to determine if there is power to the motor. This could be done with a $10.00 test light. If there is no power to the motor, locate the fuse, with the same test light, to determine if the fuse is good or not.
