Why cigarette lighters not working on a 2005 Cadillac sts?

If the cigarette lighters on a 2005 Cadillac STS are not working, it could be due to a blown fuse, a faulty lighter socket, or an issue with the vehicle's electrical system. Check the fuse box for any blown fuses related to the accessory power outlets. Additionally, inspect the lighter socket for debris or damage that might prevent it from making a proper connection. If these elements are in good condition, further electrical diagnostics may be needed to identify the underlying issue.
