David1, With regards to your 2010, see this discussion on heated and cooled seats. http://www.expeditionforum.com/threads/heated-and-cooled-seats.21774/page-2#post-231471
This was my post in Dec 2015: "I had the same issue on a 2011. Press the button for heat on either of the front seats and the light would go on and immediately go out. I checked the fuse, looked at the Ford shop manual, checked online forums, and realized it was beyond my capability to diagnose. I also saw that the DSCM would require programming that can only be done at the dealer so I took it in. The dealer found the power connector (12 pin pigtail) to the DSCM was burned as was the corresponding pin in the DSCM so I had to have both replaced. (I have the old DSCM and can easily see the burned pin now.) So, 2.5 hours of labor and a new DSCM and pigtail, my wife has her heated seats back. If you're paying full list for the parts (which I did not), expect to pay about $600 for the repair depending on your local labor rate. This is a common problem and these heated/cooled seats are a revenue source for the dealers. If it goes out again I will not be repairing it. The pigtail part number is 3U2Z-14S411-ZMB and the DSCM (has multiple Ford and Lincoln applications) was 9U5Z-14C724-B."
A reply from k9education that was very good was: "It's too late now, but this is actually the most common problem with these seats on the 3rd gens and is easily fixed. The replacement pigtail runs what appears to be 2 grounds (as opposed to one on the original) and you should be able to reach it without removing the seat. 3U2Z-14S411-ZMB is $33 from Rock Auto; 9U5Z-14C724-B is ~$200 from various sources. I'd probably just source the module from a junkyard as it is typically the pigtail that takes out the module."
It was in fact the pigtail that took out the DSCM.

I have my module from rock auto, great deal when sending core back. Since the pigtail is fine, I wanted to be sure there was only one module in the '10s, Alldata confirmed this. I didn't want to open the package but seems like it is worth the try before taking to dealer.
