AC not working 2000 Ford focus

What is your question?

So one day, I changed my AC speed from 4 to 2 and then the AC button light went away and my AC went out. I changed the blow motor because two people told me that was problem because there was electricity flowing through it. When I press the relay for the AC in the fuse box, some part of the AC under the hood makes a noise (the noice it makes when my AC is on) but the AC doesn't turn on nor will the light turn on.
