Each of my ventilated black leather seats have blotchiness or different shaded areas when viewed in direct sunlight. Its definitely not a stain and my theory is that prior owner maybe used a thick leather conditioner that clogged some of the vent holes in the seats. Anyone else have this problem? any quick fix rather than taking a toothpick one by one through a million little holes?

Careful use that is. I have used the hand attachment of such a machine on the seats using a fabric cleaner to get heavy soil off leather. You will need to be very cautious with the liquid application for obvious reasons but the vacuum limits contact time, the liquid should soften the old conditioner and the vacuum lift the contamination out.
This way the seats should never get too wet and yet enough water is present to remove the dirt.
You will need to use lexol or equivalent high quality product afterwards to condition the leather

You might try the Detailers Forum portion of AW. I'm sure someone in there has adressed this problem before.
