Sorry to hear that your car is having trouble. I'm not all too well versed in your vehicle, but can offer an option for you.
Here at NICO, we have Factory Service Manuals available free to members. Here's the direct link for the seat section of the FSM for your car:

As you didn't mention, I need to ask, have you checked the fuse and for loose connections?
