It is the seat element it self. I have had my drivers seat go out on me twice already
The element burns out/shorts out. So what happens, when you turn it one, it begins to draw two much current the module in the door acts as a breaker... i accutally have my bill from the first time it was fixed on my desk..
total, with parts and labour came to bout 300 bucks.
Keep in mind, i had the first time done up in Alberta canada, where every thing specially labour is inflated....but it was at the dealership so it probaly evened it self out
thankfuly both times i had it under warranty, but i do not have the bill from the second time when done here in vegas
