My heated leather seat recently stopped working and the light on the button just flashes for like 20 seconds then goes away when you try to turn it on. What causes this and how do I fix it and get my seat working again?

 

When there is a problem with the heated seats, the button flashes in different sequences letting you know if it is a problem with the heating element, or the relay, or some other issue. Sequences might be listed in your manual, if not, try to find them on the internet
