Fan motor works fine - Hi , med, low but blows air out of all the ducts no matter what the setting is put on ( A/C, defroster, vent, etc). First place to check ???????

Thanks,

Does the dash, vent, defrost ect lever feel like its doing something. Make sure the cable is not broken. The vacuum hoses under the dash, they operate the air duct valves too I believe.
