My drivers' side heated seat doesnt work. Can anyone tell me what would cause this? The button lights up green, but no heat at all. Is there a fuse that is blown, or could the whole unit in the seat be busted?

 

My heated seat was out of order also. I replaced the both the leather and heater sheet from a right hand drive LS from uk and now it works. So i got new looking leahter and a hot *** during the wintertime so thats perfect 8-)
