    2016 both Front Heated/Cooled seats help request

    Both front seats heating and cooling stopped working at the same time.
    From what I've read all over, it is NOT the switch(s); both switches light up, and work properly (three bars, then two then one) and stay lit on both sides, for both functions, and it reflected also in the Sync screen.
    1st troubleshoot potential = FUSE (72) in engine fuse box ...it is fine, put in new one, swapped with windshield wiper fuse (same 30A) so i know it is working.
    2nd troubleshoot potential = Seat Control Module; Cannot locate any information about this year's Control Module online; location or even the specific part number.
    - Location = Under driver's seat is the ONLY control module visible underneath either the driver OR passenger seats.
    - Part # = GU5T - 14C708 - HK; typing this into Google search results in ZERO direct matches. This is a six (6) plug module. I can't find any wiring diagrams, etc. online.
    I pulled the module, checked all the connectors and reinstalled (no burnt looking wires as some other heated/cooled seats in older model ford/lincolns have indicated a ground wire gets overloaded)
    3rd troubleshoot potential = a week or so prior to both seats no longer working, the driver side blower fan was making a noise.

    Any year and part specific diagrams, directions to replacement part module, or directions on what wires to test with digital multi-meter would be greatly appreciated.

    If you unplug that brown plug most likely you will find a burnt pin
    Others have just fixed the burnt pin and been fine
    Since mine was still under warranty I had them replace it.

    I'm wrong the burnt pin on mine was a long black plug
    You can see it in this photo the black and white strip
    This is under the passenger seat

    Thanks for the comment and picture. I removed the module and did a cursory inspection of the pins and all looked fine. I will remove it again and do a more detailed inspection. Man I hope that i missed it the first time and this is the problem.

    Do you have access to forscan it may be able to tell you if the module is working or not?

    My OBDII reader/adapter doesn't work with Forscan, so at this point I don't have access. If I did, not sure I'd know what I am looking for. I may invest in one anyway in order to change some of the annoying Ford features like the double honk when vehicle running and the key gets away from the vehicle. I did check all of the wiring harnesses up close and there is no scorching or damage to any of them.

    Brand new module arrived. Plugged it in. Everything works...except the heated/cooled seats. It is something else. Going to replace the driver blower motor that was making noise prior to both sides stopping function. This part is DU5Z-19N550-D, $107 @ getoempart.com
