Window Air-Conditioner unit motor is running but there is no air blowing?

Every air conditioner is equipped with at least two motors, the compressor and the fan motor. It is possible for the fan motor to be defective and the compressor to be running. If this is the case the unit will appear to be running and may even sound "normal" but no air is blowing out the front or back of the unit. If, after removing the cover of the unit you discover the fan blade is very stiff and difficult to rotate, the fan motor should be replaced. If the fan blade turns freely the circuit powering the fan motor will require electrical troubleshooting. It will be necessary to have a qualified technician locate the cause of the problem, which may be either a problem with the capacitor, the selector switch or the motor itself.
