How do you fix all 3 cigarette lighter's in a 2001 Mitsubishi montero sport?

To fix all three cigarette lighters in a 2001 Mitsubishi Montero Sport, first check the fuse box for any blown fuses related to the accessory circuit and replace them if necessary. Next, inspect the lighters themselves for any debris or damage; cleaning them or replacing faulty units may be required. If the problem persists, trace the wiring for any loose connections or shorts. Finally, ensure the vehicle's battery is functioning properly, as low voltage can affect power to the lighters.
