Check for 12 volt power to resistor under dash on passenger side. Follow wires from under glove box (from blower motor) to resistor, which will be where wires are connected on duct work. You should be able to test for 12 volt DC power there.
If the blower isn't working check the fuse/circuit breaker, and relay if one is used. If the blower is working, and if in the defrost mode warm air is produced then it is likely a problem with a vacuum actuator that diverts airflow in the duct system. Some vehicles have a valve that controls hot engine coolant flow to the heater core, if your vehicle has one it will be located where the heater hoses pass through the firewall check to make sure it is functioning correctly.
No the motor is not bad or going bad, the heater blower motor resister is bad, thats regulates the blower speeds, its located under dash by heater motor 2 screws hold in heater box with a electrical plug to it.
