No heat coming out of the vents?

There is no air or heat coming out of the vents. I have all digital readout controls and I can see the bars go up and down when I adjust the fan settings, so it's not in the controls. I bought a new blower fan resistor and going to install. I did notice, before that fan quit working, it would cut out and come back on, but it would stay on. I hope you get what I'm saying, as I don't know how to do videos or upload anything. I'm not that savvy with that part of my phone. Thank You.

I ended up replacing the blower motor resistor, still nothing. I then slightly tapped on the blower motor and it started working. I then shut the vehicle off and back on again, motor would not come on, tapped on the blower motor again and it started working. So, I did end up replacing the blower motor as well. Now I have heat at least. But in the summer I am going to have to replace the AC unit, the bearing went out on it. From what I was told at a dealership, if I replace the AC unit, they would do it just for the labor. So, I will buy the AC compressor, drier, accumulator and the condenser. Then I shouldn't have to worry about the AC system working properly. Thank You for all your help.
