Front Seat Heater/cooler problems of the 2010 Ford F-150

Driver heated seat function was on while driving, suddenly there was a very hot spot felt under driver's left leg, then heated seat function then went off. Further attempts to operate the heated seat function resulted in a temporary illumination of the driver heated seat indicator, followed by an extinguishing of same indicator after about 1 second. The vehicle in question is no longer eligible for coverage under the 3/36,000 bumper to bumper portion of the Ford 2010 new vehicle limited warranty; therefore, the vehicle owner elected to perform his own investigation into the problem. The owner dismantled the driver seat and found burnt components in the vicinity of a failed wire that was part of the seat heater subsystem, all of this under the seat cover in an area that would have been underneath the left leg of the driver. The failure was identified as a burnt/charred wire that opened the circuit of the heated seat function. . Read more...

My seat heater stopped working several months ago, I went to replace it today and found that the heat element had melted and turned black the seat cushion in the area of where it melted, I don't believe that there was actual fire but had the power not shut off I am sure that the seat would have caught fire.

The driver's side seat heater quit working after my wife complained about it "getting so hot it was literally burning her legs". I took apart the seat today to replace the heating pad because I had read about this being a common problem. To my surprise my wife was not exaggerating. There were burn marks on the foam insulation around a connecting piece of the bottom seat heater. My truck is out of warranty, otherwise I probably would've just dropped it off at the dealer and never witnessed this myself.
