Fan doesnt blow air at all

Hello, are the controls lit up and functional as normal? If so, check for power to the blower motor when the fan is turned on. If the controls do not light up and function as normal, focus your attention on the controls and the power to the controls. Check any fuses that may have been blown. Initially this may help, but there's still a cause of a blown fuse (if that's what it is) that must be dealt with ultimately.
