mustangary Posted February 26, 2012 Report Share Posted February 26, 2012 Driver's side heated seat quit working. Lights on dash flash-on, quickly off, when push the button. No heat. Passenger side works just fine. Anyone know what might be going on? Quote Link to comment Share on other sites More sharing options...
Scorpio Posted February 26, 2012 Report Share Posted February 26, 2012 Fuse check would be a good place to start. Quote Link to comment Share on other sites More sharing options...
moretoolz Posted February 25, 2013 Report Share Posted February 25, 2013 Hey mustangary, any solution to this. I have the same problem. A little too cold to start trouble shooting now though. Skeptical about the "Fuse check" advice from Scorpio, since the circuit seems to have power (and the passenger side works). I could be wrong. I'm thinking some sort of short that causes an overload, that's detected by the control module, and shut down before blowing the fuse. Sharing your experience would be appreciated. thx.

thirdgenlxi Posted February 25, 2013 Report Share Posted February 25, 2013 One of your seat heater elements is likely shot..... the heated seat control module continuously monitors the heater circuits for both the seat bottom and seat back heating elements, as well as a temperature sensor in each mat. If the control module detects a fault in any of the circuits or the temp sensor, it will not allow that seat heater to operate. That's why it flashes on real fast and then goes off, because it detects a fault. The heated seat module is located under the front passenger seat and controls both front heated seats. So you gotta figure out which one of your heater mats is burnt up Quote Link to comment Share on other sites More sharing options...
Dingo Posted February 25, 2013 Report Share Posted February 25, 2013 You can usually do it with a continuity tester. Quote Link to comment Share on other sites More sharing options...

The only difference was the light would stay illuminated. My wife barely used the heated seat in the passenger side, so I just swapped the elements. It was fairly easy to pull the leather back on the seat and peel the element off the foam and swap them. The swap worked until I traded it it a few years later. For all I know, it still works. Good luck! Quote Link to comment Share on other sites More sharing options...
Dr Fildo Posted December 2, 2014 Report Share Posted December 2, 2014 Does the module have to be replaced, or is it the heating element in the seat itself? I'm having the same problem, unfortunately. Quote Link to comment Share on other sites More sharing options...
thirdgenlxi Posted December 3, 2014 Report Share Posted December 3, 2014 Does the module have to be replaced, or is it the heating element in the seat itself? I'm having the same problem, unfortunately. The module itself is fine, it's usually one of the heating elements that needs to be replaced, most time the bottom cushion one. The module monitors the heating element circuits for shorts/opens, as well as the temperature, and will shut that side off if it detect a problem, hence why the lights come on and then go off real quick.... the module detected a problem in the circuit and disabled that side to keep from starting a fire or frying the module 1 Quote Link to comment Share on other sites More sharing options...
topdri68 Posted November 3, 2021 Report Share Posted November 3, 2021 I have a 2011 Ford Edge Limited. My mechanic replaced the module which did nothing as was discussed here. They ran a test on the heat elements of which is the problem. The issue is that all seat heater elements do not work and the lights stay lit on the display. I went to Ford for a second opinion and they called with an $1800 cost to replace all four elements, which is their suggestion. Ouch! Who needs heated seats?!? I am capable of working on this myself if it is even possible. Seems like a money grab from Ford if you ask me. I thought of buying used seats and am looking on ebay when I can. Nothing yet. Open to any suggestions, ideas. Thanks Quote Link to comment Share on other sites More sharing options...
