Heated and Cooled Seats not blowing

[Yankee Traveler]

So the SHO is in the shop right now...the "Stealership", because the cooled seats do not blow very well.

I have been in a number of Ford/Lincoln vehicles with the optional seats and they all seem to blow very well through both the seat bottom and seat back. This one only seems to blow through the bottom and not very well, both passenger and drivers seats.

Anybody else have an issue with this? It does blow, and it does get cold, but it takes about 20 minutes for my keister too cool off because the blower seems so weak.

Hate to say it, but this may be normal. The heated and cooled seats are heated and cooled by a device called a Thermal Electric Device (TED). Depending which way current flows, the device can create heat or pull it away. It's much better at heating than cooling. Heading it can add 100 degrees to ambient air, but cooling ota able to pull 14 degrees out of the ambient air.

There is a TED in the seat button and back, each with its own blower. That blower has to blow the heated or cooled air through the cushion and seat cover. Seems a few people report slow coolimg and heating times. I experience the same thing in my car. Seems the seat back is one of the more common poor performers. I suspect that the seat back is getting loaded with heat because there is now air flow, specifically the heat to go and dissipate.

If the heat works well, the cooled seat is probably going to be as good as it gets unless there is a restriction to air flow. This may be a dirty filter, or because the red has become misaligned with the seat fusion, or the duct work in the fusion was crushed. Since you said that the driver and passenger about the same, I'm setting your bar low for a repair.

Newer systems in Ford's stable are heated/ventilated. They have a heat mat grid, then a blower motor that sucks air though the seat.

Well, that not what I wanted to hear. The Cooled vs ventilated was one of the things I preferred about the Ford over other makes.
My wife and I test drove a new Explorer Sport and an Explorer Platinum, a new Expedition, as well as a Lincoln MKX and the airflow on the cooled seats were 10 times greater than on my SHO. My previous Lincoln LS included. I just assumed they would be the same and did not test on the SHO before purchasing. And there is zero airflow though the seat back.

I will try to attach a tissue and video to demonstrate the lack of flow.

I've had an 11 and now a 15, both heat and cooling suck on both. I had an 06 Cadillac that puts both of these to absolute shame. That car you could feel the heated seats within a minute no matter how cold it was, and you would have to turn it down a click after 5 minutes. On my SHO I can have the heat on for a couple minutes and not even know it is on. The cooling is even worse, I rarely bother even turning it on unless I have a drive over half an hour.

The other day when I set it my AC to recirc AND had my foot-well vents turned on, I think I noticed it do a better job of cooling my seats. Maybe it's because I was blowing cold air into the vicinity of the seat, making the job on the seat-installed-system easier.

But emphasis on "I think". Worth a try!

It is not the temp, the air coming out of the seat bottom is COLD!, there is just very little airflow and there is zero airflow coming out of the seat back.

What year is your SHO, Yankee Traveler?

While I can't complain about the heat or cold of the seat heaters/coolers in my 2018, it sure does seem like only the bottoms function. I don't use them that often, but I seem to remember than the either only the bottoms work....or the bottoms work much "stronger" than the backs.

My previous car, a 2006 Lincoln Zephyr had seats where both the cushion and backrest seemed to work equally well. (To be honest...not as quickly or as well as the SHO...)

I have to be on the road a bit today....I'll put it on and check it out. I can say that both my front seats seem to work the same. I haven't tried the rear seat heaters...in fact...I don't think anyone sat back there yet...

UPDATE>>>set the seat heater on full...and both the bottom and back got warm. Switching over to cool....seemed that while the bottoms got cooler...there was also some chill on the backs too. Feeling the passenger seat...seemed to be a bit higher up on the backs..
