Fastening Seatbelt Lights not on when turning ignition switch on.

What is your question?

Had fusible link wire replaced leading to starter switch because truck had no power inside. When repaired Fastening seatbelt light stop working. My question is how can this be fixed and should have shop owner fix this problem also since it was working before fusible link wire short- circuited. After shop owner was paid he said it would be another charge because he had to remove the dsashboared.
