First for seats check the fuses under the hood if you have not already. Both of my seats stopped working at same time and I was prepared to dig into the car.
But fuse replacements fixed them both. Still don't know why both went at same time.

Here is a link that should help you out.
I also find it helpful to read the daily posts as a lot of the same problems keep popping up.
When it becomes your problem, you will think back and remember someone else going through it and solving it.
