this car does not equipped with a power module, so it cannot shut down consumers. the szm will shut down the heated seats at around 11.4v, but the leds will remain lit.

It is rare for both front seat heaters to fail at the same time., i suspect the center console switching control unit has a short in it or otherwise liquid damage in it. The control unit monitors the seat temp and if a short in the temp sensor is present, the LEDS will go out. i trial fit a known good control unit before going any further with seat dissassembly.
