Sounds like you will need to pull that fuse box out and plug the feed wire to the EVIC back in. It plugs into a socket on the back of that fuse panel. You will also discover that it is a loose or burnt main feed wire to that panel that caused it to lose power. Have had to repair two of the three Blazers I have owned for that same issue. The contact gets a bit of corrosion, that causes higher resistance and that causes more heat and it fails. I generally replace the connector, clean the contact and apply some dielectric grease and make sure they have good connections. Then reassemble.
