Re: Mods to ventilated seats

When the A/C is on, the coldest air is usually coming from the dash vents. The seats draw that air to and around you. The other way, you'd be getting air from under the seat.

I guess if they actually had HVAC vents under the seats feeding cold air, it might cool you off more quickly blowing it up through the seats.

I guess that's as plausible a reason as any, and if that's the actual reason then I would certainly prefer to reverse the direction of flow.

If the AC is doing its job, you shouldn't need seats to draw the air to you. I can't see how this design could in any way be superior to the seats pushing the air and using those types in Florida heat I can tell you that the temperature of the air was never an issue.

I wonder if it has more to do with keeping the perforations in the leather intact... thinking that pushing air could force the edges of the pores to raise and rub against you entering/exiting the seat and eventually mess up the leather, where as pulling air in keeps those edges downward when running. That's my best guess.

I'm interested to see if OP tries to mod.

Maybe Custontronix could make it so the heated seats could stay on WITHOUT the engine running....like my '08 Jeep GC Limited 's' 3.0 would.

the thought of my JGC's sucking my ass sweat into the seat and calling it "ventilation" is disturbing.


DONMAR Seating Comfort Upgrades
Seat Ventilation System on sale clearance items Lumbar Support System

Hope this helps.

It really doesn't suck from the top portion of the seat that makes contact w/ your bottom. It sucks the air from beneath the seat and blows the air through the holes.

Perhaps there are more technical reasons, though.

While working as a mechanic at the jeep dealership we replaced a damaged seat that had this feature. Curiously we dissected the damaged seat to check out the mechanics and features of the seat. the seat fans are very small and they resemble the cooling fans that you would find on the back of a CPU of a computer. Im not sure what the video is explaining but the fans do indeed blow air THROUGH the holes.
