The rear defogger also gets power when the dash switch is activated. But then of course loses power when the dash switch automatically deactivates 5-10 seconds later.
Thoughts?

OK, two different things here. You said the rear window MOTOR get's power, but in your previous post you said you check the defroster with a multimeter. So just for clarification, how did you test the window motor getting power, and what were the readings? The rear window motor is activated by the rear body ecu but is interdependent on the Body ECU.
Secondly, the defogger is entirely activated by the Body ECU. As I explained in a previous post. If you pull the defog relay and power the defogger and it works, then the problem is most likely in the Body ECU or switch. Of course there is always the unlikely possibility the relay is bad, easy enough to switch it out. I would just check terminal 2 of the defog relay for ground when you activate the rear defog, if it goes right out, then the relay is not the problem. Allow me to remind you the rear window limit switch comes in to play. If that switch does not remain activated, the defog WILL NOT WORK.
So do as
