Don't blow into mics! Not good... ever. Don't plug in a mic into a preamp with phantom on NOR unplug a mic with phantom power on. Have you tried a different cable? Experiment. With the phantom power off plug then unplug and replug your cable a few times, perhaps they're dirty ... get some DeOxit and clean the cable plugs. Take your mic somewhere and try it there. Take your interface..... etc Get some experienced help to visit your set up or take those components to someone. Good luck.
