Fuse labled ctsy what does it service - Cutlass Calais Oldsmobile Cars & Trucks

Hello swatem1: My name is Roger and I will help. You did not specify a specific year car you were looking for. This is for a 1988 thru 1991. They do change things from time to time. The ctsy fuse carries power for the inside lights,power antenna,automatic safety belts (1991) and the warning and alarms (1991). Should you need more specific to d different year please just ask. Please rate the answer. This way I know it was helpful. Thank You for using Fix Ya. Roger
