there are 3 sam modules in the carI believe under the front seats for the front sam.
I believe its the passenger side, but Im not certain.
1 under the passenger side rear seat
2 on opposite sides of the engine, if you pop your hood and looking at the car there are in the top left and top right boxes, one of the boxes should have a sticker and say battery in trunk. there are other computers there but the sam is the computer connected to the fuses and disconnects from the fuse box.
if you think its your sam i would take a look and see if you find any water or corrosion on the connections on all the sam's. but make sure your disconnect your battery before disconnecting anything
