Cooled seats not cooling

[Droid_Junky]

The heat doesn't seem to be coming directly from the fan air. It seems to be something like you see in heat blankets built into the seats but the air leaking around the vent is cooler with the heat on but maybe it will be if the fan is on low because it isn't pushing as much air around. The heated seats process seems to be happening after the fan. The fan is actually cooling it down a little??? The fan has three speeds. Low is on when the heat is selected and low, med or high is on when cool is selected.

See if I had attempted something like this i would have likely electrocuted myself. Well done sir

I've scheduled an appointment for 9am tomorrow. It's about a 35 minute drive so it should be nice and warm by the time I get there.

Take that thermometer!

This feature works fine on my car--there is no refridgerent lines running up and down the seat--it just moves ambient air threw the holes. If you are sweating and the air blows on you the sweat evaporates quicker giving a cooling effect--pointing a thermostat isn't going to show anything colder than ambient air. I couldn't even read all the posts on this thread-such nonsense.

Not trying to be difficult here, as I'm still relatively new, but the only nonsense is coming on here and saying the problems we've been having with our seats is nonsense. The back of my seat doesn't cool, it should but it doesn't. It doesn't blow cool air, it doesn't blow ambient air, it doesn't blow any air at all. It does have a fan however that reaches in excess of 100+ degrees. Clearly there is a problem.

So what you are really saying is that you don't understand how a digital infrared thermometer works? They are actually extremely accurate at measuring temps in this way. https://en.wikipedia.org/wiki/Infrared_thermometer

Yours works fine, great! Many other people seem to agree that it's not working. My car is covered during work. I sit at a desk most of the day so i'm not sweating when I get in the car. Even with the air maxed for 35 minutes the back is hot to the touch.

Running ac max turns off foot vents which reduces effectiveness of back cooler try it be amazed

LoL ... it's not nonsense, it's scientific research! Obviously the unit in the seat back is supposed to cool like the one in the seat bottom, otherwise it wouldn't have those big power wires going into it. Or maybe Ford just put some dummy wires on there to throw everyone off? :doh:

If you would have read the whole thread, you'd understand that it cools by using electricity, not "refrigerant lines". And only a few members have actually claimed (without real temp measurements) that their seat backs get cold. Could be they were just sweaty and the ambient temp air blowing on their sweaty skin made it feel like the seat backs were providing cooling.

Yes i had max and the foot vents selected. It only helped the bottoms. The back seat has almost no gaps to get that air.

I noticed something from your pictures.

First notice the bottom unit, the white circle that looks like a peace symbol. I'm assuming that is the fan itself. It is uncovered and evidently able to flow air or do its thing if its a Peltier unit.

Secondly, as you said, notice the back unit. It has that stupid cover that closes off all but probably 2% of the area of that fan. You can see the white with the small holes behind that cover. I would assume this should look just like the bottom piece.

I'm wondering if that plastic cover was removed if these would function more efficiently or not? Just a thought.

I'd be willing to bet if someone would cut slots or drill holes into the plastic piece to allow more air flow/movement through that fan that the back would cool a little better. I'm sitting here in front of my computer with a small fan blowing on me. If I stick a book (an obstruction) in back of the cage of the fan the flow lessens greatly. If I remove that obstruction the fan flows just fine. It seems to me Ford was worried about this getting damaged being in the seatback (someone kicking it from the back seat) and put this plastic piece over it. I would guess they should have put a grate/cage instead of a solid piece and it would protect AND allow air to flow through.

^^^ With the fan cover off the Peltier unit, it might help the air flow through the fan. But as Droid_Junky discovered that even with the seat back opened up (to get air back there) and running the coolers on the high setting, the outlet of the Peltier unit duct got hot (110 F).

Maybe he can get that fan cover off and test some more to prove if that changes anything. That fan cover must be on their in case someone in the back seat presses up against the seat back, which would block the fan inlet.

Here's a "what if" ...
If the back unit seems to start cooling like the bottom unit after the fan cover is removed, then a simple fix might be to drill a bunch of holes in the cover so it can intake air more efficiently, and still act as a cover to prevent the seat back material from blocking it if it gets pushed up against the fan inlet.

I didn't realize these seats used a peltier. The hot side of those generate quite a bit of heat and are terrible about condensation on the cold side.

I have a high quality temp gun and I believe my seats are functioning properly if it would help you guys I'd be happy to take measurements on mine.

That would be great to do if you think yours are working right. You might want to duplicate what I did in Post #83 ... except I didn't measure the seat temp on the backside where the unit resides. Next time I have a chance, I'm going to repeat the test I did in Post #83 and also monitor the backside of the seats.
