Electrical problem
2005 Buick Terraza 6 cyl Front Wheel Drive Automatic 71000 miles

I own a 2005 Buick Terazza, the drivers side electric seat will not obey any of the switches on the seat itself nor will it respond to the preset buttons on the drivers side door for the two drivers. I have replaced the two circuit breakers in the interior fuse block this did not help. There is no sound from the motors themseleves. I do get intermitten results when I take the circuit breakers out and then replace them. Is there any other electrical fuses or breakers or anything I can check.
