So, the lights on the dash aren't working, but do the pads heat up?
Check the plugs going to each seat.
Other than the fuse, there should be a relay, which could be bad, but doubtful, so that would leave the individual pads (heating elements) and those Do not all die at the same time. They have about 1.0 ohm resistance when good, 0.01 ohm if shorted, open reading if the element is broken. You could disconnect the wiring and check resistance at the plug end going to the seat.
