Is the new pigtail wire assembly a splice in plug and play? I noticed that the ground on the original is what is burning out and wondering if the replacement has the two ground wire system?

Problem: 2014 Expedition Limited, driver side only, the heat/cool function switch will illuminate for about one minute then go out.
I bought the connector and went to change it out but my driver seat has much larger controller with different connectors that have almost twice as many pins. All of the pins and sockets are in excellent shape, with no indication of failure.
As Written in previous posts the seat is heated and cooled by heated or cooled air. I just replaced the seat cushion and seat covers with products from the SeatShop, and I recommend that to anyone willing to invest the time. During that installation I was able to view everything inside the seat assembly. There is no connector under this seat like the one picture in previous posts.
My gut tells me it is something causing the current to limit and the software to shut the circuit off. If I didn't spend all day on the seat cushion and covers I might have spent more time on checking the fan. Winter is coming....

I've got an '11 Expedition XLT+. Had it since new. 300,500 on it now. I doubt you have a connector or control module issue. I think your cooling/heating blower module is gone on the driver's seat. They don't last. I have replaced three of them. Wife liked to run the seat heat 100% of the time she was driving but it's my daily driver now. It's not a hard job but you do have to pull the seat. Sounds like you have a lot of experience at that already. Part number is 9L1Z14C724C. They're available. https://www.ebay.com/itm/317077063256 When my next to last one went out I cannibalized it from the passenger side because they weren't available anywhere. Same part number driver or passenger. Once the cannibalized one went out I gave up replacing it. Looks like you can get on eBay for $280. That's very reasonable. If I thought I was going to keep the '11 much longer I'd probably replace it at $280 but I think I will sell in the next 6 months or so. My advice: cannibalize the module from the passenger seat and put it in the driver's seat to troubleshoot the issue. If the passenger side module works on the driver's side put the bad one on the passenger's side and be done. If you want to heat the passenger seat you can always buy a new module for it.

Hi Gumbyalso,
I did get a used fan from Ebay and swapped it out. And as you might think, it's used, but is it good? The fan came on but there was not change in temp on the air blowing out and the circuit shut down within a minute of operation. I might take a chance on new "New" module, but it would be better to have a way of checking the old by either powering it up on a bench or checking resistance.
Thank you for the response by the way. I hope that I can do the same for the group.

I'm sorry to hear you bought a used blower module. That's one of many items you don't want to buy used unless you personally pull one at a junkyard and only from the passenger's seat. Typically too much use on the driver's side. As I mentioned earlier, I recommend that you pull the module from the passenger's seat if it is known good and put it into the driver's seat. If you don't care whether the passenger seat is heated you can install the known bad one back in it and be done. I suppose it depends on how much whining you can take coming from the passenger side during a RI winter. If this was a control module issue neither seat would work so almost definitely the issue is a 9L1Z14C724C.

Hi Gumbyalso,
You were right about the used unit bought on Ebay, it was DOA and pretty upsetting considering the pain it is to install it. After that experience I bought a new one, plugged it into the seat module connector and tested first. I did get a refund on Ebay for the DOA module, so the only loss was my efforts which are more chalked up to learning the ropes. So I have my old and the let me keep the DOA and I plan to tear them down and see what fails inside.
I am amazed of how many points of failure there are for this system (connector, controller and module).

SM,
Thanks very much for the follow-up. Usually you only get that when someone wants to tell you how wrong you are/were. Glad to hear you have it fixed. In re-reading one of my earlier posts I see that I wasn't specific about buying a NEW one on eBay. I just said that they were available on eBay for around $280 and didn't specify new. I can see how I might have accidentally encouraged you to buy used. Sorry for that.
I haven't sold my '11 Expy yet and have not replaced the seat blowers. I regret that some mornings even here in coastal NC.
One of my sons moved to Newport a few weeks ago. He has gone through a couple winters in Bath so should be prepared for winter in Newport.

Gumby,
Winter in Newport is a challenge this year but I am so glad I bought the 26 Tremor and even more glad that I undercoated it before the storm.
I just noticed that I didn't update you... I traded in my 2014 for a 2026 Expedition Tremor. Some new ass for that seat in 2014 is thanking me right now. The seats in the Tremor are incredibly comfortable.

SM,
That 26 sounds nice. We are in the midst of that bomb cyclone that is hitting the NC coast so I should get to do a little snow driving myself when we start digging out on Monday. This is the first time the Morehead City NWS office has ever issued a blizzard warning. Should be fun. The state brines the main roads and maybe we'll get to see a snow plow.

Hi Gumbyalso,
I am heading to Virginia Beach (Little creek) to celebrate my buddy's retirement on the weekend. My first road trip in this new ride, and looking forward to it. Maybe we will see some snow on the way down. There is no way it will be like what we have here right now.
Glad I undercoated...
