Hello and welcome to JustAnswer!

It sounds as if you have a poor connection internal in the fuse box if that's what you're hitting, there aren't any connection issues, bad fuses or relays, and that is truly allowing the a/c to work.

With the engine running and a/c not working, if you hit the fuse box does the a/c come on immediately?
