2001 Limited Seat Heaters

Hi All:

The seat heaters on my van have stopped working. One garage said i need to replace the element (which includes the side air bag) cost of around $800/each (OUCH). It seems odd to me that both seat heaters are out at the same time and in both cases its the element? ideas??

Obviously there must be a fuse somewhere I would start there . Do you know if there is power to the seat or not ? It does seem odd that both would be out .
