I'm on 0302 and P3Dv4.5HF3

I got all WINDOW OVERHEAT failure when landing at ROAH, the OAT is only 28C
And they didn't trigger the Master Caution as I repeated on other topic, so I didn't noticed them until shutdown.

So I turn off the switches, after little cooling time,the OVERHEAT goes out.
Then I turn the switches back on, the ON green light not show, as if it's already in operation temperature, that's ok. but after a little while, the OVERHEAT turns on again.

If the ON is not shown, then the window should not be heating, how could it be OVERHEAT :(

BTW if I hold PWP TEST, the ON will lit, but no matter how long I hold it, they won't OVERHEAT.
