1999 Chevy Express heater motor

The info I looked at was for a G-1500 chevy express passenger van. You can check applicable fuses. Not only check the fuse, check that the fuse circuit is hot, when it should be. Also, take the blower motor connector loose, use jumper wires for voltage and ground from the battery, use inline fuse. If the blower doesn't run, I suspect the blower motor is faulty. If the blower motor does run, you have to check some of the other circuits.
