see previous response

have you changed the thermostat, check the rad cooling fan operation, checked coolant circulation, check for coolant leak, checked for head gasket problem, checked for a restriction in the cooling system. you don`t say what if anything you have done to eliminate a cause.

You need a starter or bendix spring repair.

On this website you find information (diagram, description and location) about fuse boxes in Cadillac Seville (Fifth Generation; 1998 - 1998)

Not exactly sure, but I might be able to point you in the right direction: Haynes or Chilton's repair manual located at your local library for free check out otherwise around $20 bucks at the auto parts store - great reference to have around.. Alternatively you could GO TO (not call) the parts department at your local dealer, they can pull up a photo or schemata and help you with exact info.
