How come is a fixed phrase with fixed uses of its own.
- It means, as you have divined, why, and may be used, like why, either as the head of a noun phrase, or as a bare interrogative, or as an interrogative head; but as an interrogative head it does not take ‘DO-support’—that is, it is followed by an ordinary clause in indicative form: And that's why I went to the party. ... And that's how come I went to the party. Why? .... How come? Why did you go to the party? ... How come you went to the party?
- It is never inflected: we never say ✲How came or ✲How has come or ✲How comes or anything of the sort.
