In order to verify that the blower motor is bad you will need to disconnect the bower connection to see if harness is getting power and ground in all speeds? You can put a test light between blower connector and operate blower switch in each setting speed to see if light stays lit in each position. If it does then check blower connection then replace blower motor and connector harness if it is burnt.
