1. Check the Fuse: This is the most common cause of a non-working lighter.
* Locate the fuse box: Your 2002 Ford Explorer likely has two fuse boxes – one under the hood and one inside the cabin, usually under the dashboard on the driver's side. Consult your owner's manual for the exact location and a fuse diagram. The diagram will show which fuse is for the power outlet (cigarette lighter).
* Identify the correct fuse: The fuse will be a small glass or plastic component. The amperage rating should be printed on it.
* Check the fuse: Carefully remove the fuse and inspect it. Look for a broken filament (a thin wire inside). If the filament is broken, the fuse is blown.
* Replace the fuse: If the fuse is blown, replace it with a fuse of the *same amperage rating*. Using a higher amperage fuse is dangerous and could cause a fire.
2. Check the Lighter Itself: If the fuse is okay, the problem might be with the lighter itself.
* Inspect the lighter: Remove the lighter from its socket. Examine it for any obvious damage, such as a bent or broken element (the metal coil at the bottom). Also check the connector at the base for any damage or corrosion.
* Clean the lighter: If there's any debris or corrosion, carefully clean the lighter's contacts with a fine-grit sandpaper or contact cleaner.
3. Check the Wiring (Advanced): This requires more technical skill and is only recommended if the above steps don't solve the problem.
* Disconnect the negative battery terminal: This is crucial to prevent accidental short circuits.
* Access the wiring: You may need to remove the center console or other trim pieces to access the wiring to the cigarette lighter. This involves removing screws and potentially prying carefully with plastic trim tools to avoid damaging the interior. Consult a repair manual or online forums specific to your year and model Explorer for guidance.
* Test the wiring: Use a multimeter to check for continuity (a complete electrical circuit) in the wiring. If there's a break in the wiring, you'll need to repair or replace the damaged section.
* Reconnect the wiring: If you've made repairs, carefully reconnect everything and ensure all connections are secure.
* Reconnect the battery: After completing repairs, reconnect the negative battery terminal.
Important Considerations:
* Owner's Manual: Your owner's manual is your best resource for specific information about fuse locations and amperage ratings.
* Repair Manual: A repair manual (available online or at auto parts stores) can provide detailed instructions and diagrams for accessing and repairing the cigarette lighter wiring.
* Professional Help: If you're not comfortable working with car electrical systems, it's best to take your Explorer to a qualified mechanic. Incorrect wiring can lead to damage or even fire.
By systematically checking these points, you should be able to identify and fix the problem with your 2002 Ford Explorer's cigarette lighter. Remember safety first – always disconnect the negative battery terminal before working with any car's electrical system.
