Sounds like you have some major shorting wires under the dash. Make sure all your wires are correct coming into and out of the fuse box. You may have some lose wires touching there. Is your ground correct after replacing all the item mentioned? Did you have this problem before having or doing the work? Recheck all connections and wiring. It appears to be electrical.
