The cigarett lighter outlets do not work.

Most likely you have something metallic that entered/fell inside one of the cigarette lighters.

I once found a dime inside a cigarette lighter which my children assured me was placed there by a shadowy personage named "Notme". Go figure.

While the fuse is REMOVED, look inside each lighter with a flashlight and remove the foreign material.

If you find nothing inside the lighters, disconnect them all from the electrical system by removing the single wire attached to the rear of the lighters. Replace the fuse.

Alternately, you can disconnect them one at a time, replacing the fuse after each one. You may need a few fuses for this.

If the fuse blows after ALL the lighters are disconnected, you have a wiring short circuit which is best diagnosed by a professional.

If the fuse does not blow, begin reconnecting the lighters until you see a spark, or the fuse blows again. This is the faulty lighter, replace it and your problem is solved.

Note: You cannot get shocked or electrocuted by your car's 12 Volt system but you can be burned by heavy sparking. You can reduce the risk of heavy sparking by using a lower-rated fuse during the testing. Wear saftey goggles and latex gloves for safety.

Good luck

Make sure that there are foreign objects,ie- coins,etc. in any of the power outlets/cigarette lighter outlets. if that checks ok and the wiring going to the outlets are ok sometimes u can have a bad cell phone charger that causes the fuse to blow.if that doesnt work get a WIRING DIAGRAM so u can see exactly what is involved in the circuit.
