My ac stopped blowing air into the cabin, doesn't even blow hot air. I changed the resistor and it worked for a day then quit working. Can someone please help its 100 degrees outside and I'm burning up. 2001 f250 7.3

Is there flow volume/pressure coming out anywhere, floor, dash or defrost position?

If you're fan runs, there should be flow ..... somewhere, if the fan has an available supply and outlet media (air) path. However, if you have no vacume the in dash blend door doesn't work. Usually defaults to the defrost position. Do you hear the vacume pump when you " wait to start " KO?

Fans are not blowing, I hear vacuum pump and I see the blend door move when I turn ac on/ off. Air came on randomly today when I was driving but now it’s not blowing.

Help me understand.

What does not work?

The A/C or the fan?
