I included this in my response, but it was probably missed.

Try lifting the hood on the latch arms. Open hood, turn latches to the locked position and setting the hood down. This provides a 3/8" or so gap to vent air.

If this works, then you'll have an idea if venting solves or at least helps with the problems. It's a no harm, no cost test. But you'll still need to be proactive with a manual fan switch.

As I mentioned previously it worked during summer cruises in stop & go traffic, often on 90+ days.

Hope you find a solution; I can appreciate the frustration.
