Ford focus air won't blow, I've replaced switch, blower motor, blower resistor, checked fuses, What else?

Question

have also checked to make sure all the wiring connections are snug and non of the wires look damaged. What else could possibly be wrong?

Answer 1

Could be a bad ground at the motor---check for power at the motor wire with switch and ignition on. If there's power, try running a ground wire from the battery negative post or good clean ground to the metal case of the motor or ground terminal on the motor, if any---if it still doesn't work, the motor is bad. If no power at the motor wire, you'll have to trace back through the circuit for a bad wire or connection. Remember, 12 volt circuits need a good ground to complete the circuit....not just power to the device.
