I ended up pulling my seat out and taking it apart. No wonder these things are expensive the parts count in just the left front seat is ridiculous. In my case the leather and heating pad is sewn together. So I had to cut them apart to find the burnt spot where the wires had come apart. Some models this is not the case. I got the smallest gauge wire from the hardware store and soldered it together after cutting out the bad part. It's been over a year now and hasn't caught fire yet. So, so far so good.
