9 months ago my headlights, door locks, and trunk release stopped working. on 1996 Buick Century

The car still ran, I returned to same shop this morning as they fixed it last time with my advice after extensive research that it was the coil. The mechanic is no longer there, and they have no records and they seem to think its not the coil although it was the fix last time, even the auto parts place said its not either, HELP!!

I really cant see it being the coil I would check your fuses first and go from there
already did, upon more research today,it could be the Fuseable Link..going to have that tested tomorrow. What are your thoughts on that and Thank You for your response..
