Rear window defroster plug

[Hoginedgewood]

So im researching the 2022 2500, they talked about the back window exploding, from the defroster wires. I've never had much need for a vertical window crusting over, so im planning to unplug it as soon as I find where the plug is. Rumor has it that it's behind the rear seat.

Im wondering if it's got it's own fuse?

please, more info, inks, etc?  The rear defroster is linked to the heated mirrors I think.  How is it exploding, from the heat?  The solid rear window or the window with the slider?
