To test the blower motor in a 1994 Chevy truck, first ensure the vehicle is off and the key is removed. Disconnect the blower motor's electrical connector and use a multimeter to check for voltage at the connector while turning on the ignition and setting the fan speed. If there is voltage present but the motor does not operate, the motor may be faulty. If there's no voltage, check the blower motor resistor and related fuses for issues.
