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.
