To troubleshoot the problem, you will need to:
1. Disconnect the negative battery terminal.
2. Remove the center console trim panel to access the fuse box.
3. Locate the fuse for the cigarette lighter (it should be labeled) and remove it.
4. Inspect the fuse for damage. If it is blown, replace it with a new fuse of the same amperage.
5. Reconnect the negative battery terminal.
6. Test the cigarette lighter to make sure it is working.
If the cigarette lighter still does not work, there may be a problem with the wiring or the cigarette lighter socket. You will need to take your vehicle to a qualified mechanic for further diagnosis and repair.
