Yesterday I noticed the heated seat on the driver side is not working. I also verified the cooled feature/fan is not running either. Passenger seat operates normally. Wife said she feels the driver seat has been working intermittently but thought it was just her. The indicator lights on the switch do light up. After some internet searching I have found the heated/cooled seat module part # GU5T-14B663-AA (or similar) typically located under passenger seat in Fords is prone to burning a wire and melting a connector, typically rendering the driver heat/cooling feature INOP, likely due to the driver side being used way more than passenger side. Looking in our Edge I don't see this module under the passenger seat, but I do see a similar module under the driver seat part # GU5T-14C708-JP (off to the right the letters DSM). I am assuming this Driver Seat Module controls the memory seats and the heated seats in our Edge? Anyone with this issue or knowledge of problems pertaining to the Edge ST/ Edge with the memory seats and heated/cooled feature?

Ok, so there is a separate module for the heater still on my 2020? I was hoping this is the case. Still located under passenger seat? It is cold out and the Edge isn't here, but I am hoping it's just the burnt wire that seems to be the culprit a vast majority of the time on various Ford vehicles.

Thank you both. I doubt I'll dig very far into this. The memory seat 1/2/3 has worked for the most part since we purchased the Edge new in April 2021. The easy exit/entry never worked properly, sometimes putting us right on top of the steering wheel, despite a new DSM, so we just disabled that feature in the settings menu. So seeing the heat/cool is controlled by the DSM is deflating for me. This has been the biggest POS I have ever owned to be honest and I am a pretty loyal Ford guy. This Edge has tested me and more so my wife so we will likely go in a different direction on our next purchase. Sad because we love the damn thing otherwise, just wish it wasn't constantly needing fixed.  

 

Looking thru the PDF documents that HAZ kindly posted, I feel I can eliminate F74 & F77 because they would affect both front seats and passenger is working. Potentially S374 & S376 could be the culprit, but that seems highly unlikely. My best guess is either at one of the connectors like 341B/C or the DSM itself since they also share the ground G303, again a splice in there that seems unlikely to be bad. Snowing today, so it may be months before I can actually unbolt the seat and get a good look. If we even have the Edge that long.
