I took my 05 lr3 to the dealer for the driver seat heater not working, he said he ran all the checks and its not a fuse or the deteriorated wires in the sill, but probably the thermistor is out, has anyone repaired this, I cant seem to find anything related to thermistor?

 

If they mean the heat pad element it is part of the the seat cover, you have to remove the seat and disassemble it, the lower cover is a pita its held with hog rings
