Heater Cores and Blower Fans

If the heater fan doesn't work and all fuses are good as is the blower motor relay what's the problem with the heater fan?

Motors do go bad. Directly wiring the fan to a 12 volt power

source will tell you if the motor is toast. If it won't work when

directly wired to a power source, look for another motor.
