Where is the breaker located for the heating elements in the seats? Both died at the same time and I get no lights for troubleshooting.

Nevermind, I found it. That was not the problem though. I got no lights at all, and this all at once for BOTH seats.

Ok, now its cold. What is the white box under the console portion of the front seat? Is it a seat heater controller or something to do with this problem possibly? I can't see both seats' grids going bad at the same time. I get no lights on the switches themselves, therefore no trouble code; I've swapped the relay with a working one; I have some voltage to the switches (although I don't know the pin-out, there is a voltage present on some pins). What else is there?

Do your seats have high and low heat?
If the light is blinking it should either be the high or low light.
If both lights are blinking it usually means the element is shorted.
If the high is flashing the element has an open circuit.
If the low is flashing then it showing sensor out of range. or it's unplugged under the seat somewhere or a break in the wire.

Thanks Richard. I actually took the bottom pad off and removed half of the leather seat cover to find a wire that broke and burned a small hole in the foam. Reconnected wire and it works as good as new!

Glad to be of help!
