At times I'll turn on the AC for a few minutes and that seems to cool things down and cut down on the heat from the vents.

It seems to happen most just after a restart. ie home for lunch. warm air out the vents when everything is pretty much off. Outside ambient is cool. Like today. I'll turn the air on for a few miles and that seems to cool off the heater core.

to me it seems like the heater valve doesn't fully close (or core stays hot) and that's where the hot air is coming from.
