1999 911 Seat belt alarm Light & Buzzer

Vehicle Information: Model: Carrera (11; Year: 1999; Body Type: Coupe; Total Mileage: 73500;

Is the seat belt alarm controlled by a fuse in the fuse box?? I own 1999 Carrera 911, and the seat alarm does not operate on both seats. It to happen when I started the car and was changing radio stations. I looked in the fuse box directory and I could not find aa listing. Asked at the dealership, and wanted me to bring it in for a service, and would not answer directly.
