i just had my drivers seat replaced due to a faulty seat heaters. the upper & lower seat heaters went bad in my car.

the upper part of the seat receives ~ new foam & seat heater... leather covering is reused.
the lower part of the seat receives ~ new foam, seat heater & leather covering.

the red light when activated still illuminates weather the seat heaters work or not.

the dealer will not replace the entire seat as a whole assembly... only the parts listed above.
