Heated seat is not working

The passenger headset is not working anybody can help what can be wrong from their own experience

 

It's usually the seat heater pad. The passenger side the pad is attached to the fabric, so its an expensive replacement. Quite common for early 3rd gens.

 

Here is another thread with many posts.

So it’s the pad, not the plug/wires too small for current? I’ve replaced my amp and now the plug is burnt. So, I need to replace the whole element in the seat? Possible short in the element causing it to fail?
