Today I decided to work on the heated seats. I based my work off of Archon’s writeup:

I pulled the front of the seat cover on both seats and didn’t see any burn marks. I put everything back together and threw in the towel. At that point, I was thinking it was either the seat back, the module, or some other small wire that I wouldn’t find.
Then later in the day I got a second wind and pulled the entire seat out. I took off the bottom section.

I started with the biggest connection area and cut back some of the foam. I was pleasantly surprised to find a broken wire.

I took some alligator clips and put them on the wires.

And then closed off the circuit to the seat back connection.

And hooked it up in the car.

And what do you know… it works….

So then I soldered some solder wick onto the wires

And covered it up
Now to the drivers side. I decided that I wasn’t going to pull the whole seat out, just the bottom. Only 2 – 10mm nuts hold it in place.

After disconnecting all the connections, you have the bare seat bottom.

Then remove the foam/leather from the base.

And the leather from the foam.

Here is the section that was bad on the passenger one…

And this one has the same problem.

Here is the burnt end of the wiring buried deep in the foam

The other connection was good still

Starting the soldering

Leave a little slack

Tape it up

Both seats work great!
