Hello, The green relays were used for the leather seats. I would check to see if there is voltage present at the wires to the heating element. There are two wires that feed in a loop from the bottom cushion to the top cushion, disconnect and check for voltage. If there is voltage then check for continuity of both coils to determine if it is bottom or top cushion. If you have a pick and pull nearby use a passenger seat coil as they usually have less wear and tear. Its not that bad of a replacement and you can use zip ties instead of hog rings to put the seat back together.
