It's pretty hard to know of a god's wishes, wants, or desires when he never makes himself evident, isn't it?

Of course, but given that the god in question was defined to have no wishes, wants nor desires, it doesn't seem to matter much to me.

Yes, that would be knowledge, but that would be entirely opposite of what deism is. Deism is an agnostic belief. If Deists were to suddenly gain knowledge of a god's existence, then their presence is knowable, and thus you are no longer a Deist. You can't have it both ways.

I can't wrap my mind around this.

Premise: Deists gain knowledge of god's existence in the past.
Conclusion: God's presence (or the lack thereof) in the present is knowable as a result.
Problem: There's nothing about the deistic god that guarantees this.

Premise: God's presence (or the lack thereof) in the present is knowable.
Conclusion: Believer is no longer a deist.
Problem: God's presence being knowable seems to suggest that it can either be affirmed or denied. In the case that it is affirmed, I'd agree that deism is then proven false. However, if it is denied, deism is correspondingly proven true.
