Funny but I see a 34 degree difference. Is this with both intake and exhaust tubes?

So I am finding that the intake is too restricted by adding a tube to try and suck air from under the seat. I am trying a few things to make the hose bigger but the seat just doesn't have the room to do it. I am printing a cover for the intake that basically extends how far down the air gets sucked from. Hopefully the extra few inches lower in the seat helps.

For every degree the intake air drops the cooled air should also drop a degree as long as the exhaust is flowing freely.
The lower you can pickup the intake air the better it should work.

Those rear AC vents could be tapped somehow. Some flex hose from within the console lol.

So if the seats get too cold just turn on the ted and it will warm up. Hrmm.. (appreciate the effort here, its clearly a faulty subsystem).

Exactly! I am trying to get the intake inlet as far away from the exhaust side as I can. I have some limitations to my 3D printer so we will see how far I can get.

I looked for a clean way to route from the center console to the seat but there are NO gaps in this dang seat really. Or even the floor vent under the seat.

same here i put a supply line running to under the seat, but just took it out and left the duct but did not seal it to the inlet, then on reaasembly left the u channel open and just used the elastic...seems to run better...my weak link now is the exhaust ,,,need a better fitting and a larger exit duct, or to exit to the top of the seat without ruining the seat

Just an update from dealership. Sorry to interrupt this conversation.

My replacement blower came in. Apparently it was faulty. Doubt this changes my dilemma but I will let them try at least three times.

Thanks for all the work guys.

Default Cooling Seats - Are Your Seat Backs Working Properly?

Anyone ever looked at the back of the heated/cooled seats on a Silverado? They have a plastic vent on the back of the seat. One side for intake and one for exhaust directly through the mid back of seat into the TED. Seems like a logical and easy solution vs changing parts or running hoses. I wonder if there is a art number for it and if it can be reverse engineered to work on ours
