Heated/Cooled seats
Wondering if someone can educate me if the heated/cooled seats work off a "Peltier system" for hot as well as cold and is that system independent of the trucks electrical system (no resistance wires for seat heating from trucks electrical system). Understanding it needs power but does it make it's own heat.
Reason is when I plow I max heat the defrost to keep windshield hot to melt snow. I have tried having the seat on max cool (3 bars) and noticed it helped in the beginning but seemed to do nothing after a half hour or so. Was that my imagination or is it's efficiency limited by duration. What kind of amps do you think it pulls for max cool ? It's efficiency must be related to ambient (inside truck) temp and I don't have the a/c on but the heat, wondering if that is a big factor, or if it doesn't care much about that ?????????????????

I do remember reading somewhere in Ford literature that they no longer call them air conditioned seats but something like air cooled
I know that doesn’t really help you but I imagine they made the change because others were complaining too. Hopefully somebody with additional info can comment and help you.

I think they stopped the Peltier system in the 18 or 19 model. Now they are just ventilated which means they are the temps of the cabin air. Not really looking forward to that here in Texas on my new 21, but oh well.

Rebuilt a junk yard seat and discovered , yes they use Peltiers on certain models for heating/cooling. Peltiers do work but they are highly inefficient and will be severly impacted by the inability to transfer waste heat away by limited airflow, (clogged exhaust or high ambient heat on the heat side of the Peltier.

Has anyone noticed that High/setting3 of the heated seats aren't really all that hot (in my '19 F350)? At least compared to other vehicles I've been in. Sad. 
The cooled seats on setting3 are welcome on hot days.
But all in all, I'd really like to upgrade to the German scheel-mann's...
