Your Ford F150 cigarette lighter not working is a common but frustrating issue, especially when you need to charge your phone or power a device on the go. The good news? Over 90% of cases are caused by a simple blown fuse that takes less than 10 minutes to fix. This guide covers exactly which fuse to check, where to find it by model year, and how to test the socket to get your power outlets working again.
Whether you drive a 2004 XL or a 2020 Lariat, you’ll learn how to diagnose the problem, replace the correct fuse, and prevent future failures without any guesswork or unnecessary trips to the mechanic.
Check the Correct Fuse First
The most frequent cause of a Ford F150 cigarette lighter not working is a blown 20-amp fuse. However, the fuse location and number vary significantly between model years, so checking the wrong one wastes time and won’t fix your issue.
Locate Your Fuse Box by Year
Ford moved the cigarette lighter fuse between 2008 and 2009, which is a detail many owners miss when troubleshooting.
For model years 2004 through 2008, the fuse box is located on the driver-side under the dashboard, left of the steering column.
For model years 2009 through 2020, the fuse box is located in the passenger-side footwell, near the right knee area.
Do not check the under-hood fuse box unless specifically directed, as the cigarette lighter circuit is almost always inside the cabin.
Identify the Right Fuse Number
Use this reference table to find the exact fuse for your model year.
For 2004 through 2007, fuse #41 is the cigarette lighter fuse with a 20-amp yellow rating.
For 2008, fuse #41 is the cigarette lighter fuse with a 20-amp blue rating, and it also powers the OBD2 connector.
For 2009 through 2014, fuse #22 is the cigarette lighter fuse with a 20-amp yellow rating.
For 2015 through 2017, fuse #89 is the cigarette lighter fuse with a 20-amp blue rating.
For 2018 through 2020, fuse #68 is the cigarette lighter fuse with a 20-amp rating.
Later models may label the socket as a power outlet instead of cigarette lighter, but it’s the same 12-volt circuit. If your front USB ports also aren’t working, check fuses #135, #139, or #58.
Pull and Test the Fuse
Open the fuse box cover, which includes a built-in fuse puller and a printed diagram showing fuse locations.
Use the puller or needle-nose pliers to remove the suspect fuse.
Inspect the fuse visually by looking for a broken metal strip, blackening, or melted plastic.
For certainty, test with a multimeter in continuity mode. No beep means the fuse is blown.
Never replace a fuse with one rated higher like 30-amp or lower like 10-amp. Use only a 20-amp mini blade fuse.
Replace the Blown Fuse Properly
Swapping in a new fuse is simple, but doing it incorrectly can cause recurring issues or damage to your electrical system. Follow these steps to ensure a safe and lasting fix.
Install the Correct Replacement
Purchase a 20-amp mini blade fuse, which is standard across all F-150 model years.
Insert the new fuse firmly into the correct slot until it clicks into place.
Close the fuse box cover securely.
Some 2018 through 2020 models have multiple power outlet fuses including #51, #68, and #32 through #34. If rear or console outlets are also dead, check those as well.
Test Immediately After Replacement
Turn the ignition to the ON position. You don’t need to start the engine.
Plug in a known-working device such as a phone charger or tire inflator.
Look for the LED ring around the socket, which should glow white or blue when powered.
If the new fuse blows immediately, stop and do not continue. This indicates a short circuit that requires deeper diagnosis.
Diagnose Multiple Outlet Failures
If more than one 12-volt outlet isn’t working, the issue could involve multiple blown fuses or a shared circuit fault. Don’t assume one fuse controls all outlets.
Check All Power Outlet Fuses
Later F-150s have separate fuses for different outlets.
For front dashboard outlet, check fuse #22 for 2009 through 2014, fuse #89 for 2015 through 2017, or fuse #68 for 2018 through 2020.
For center console outlet, check fuse #66 for 2009 through 2014 or fuse #92 for 2015 through 2017.
For rear outlet, check fuse #72 for 2009 through 2014 or fuse #91 for 2015 through 2017.
Test each fuse individually. A dead rear outlet with a working front one usually means only fuse #72 or #91 is blown.
Is It Just USB Ports That Failed
Starting in 2018, USB charging operates on separate fuses from the cigarette lighter.
Fuses #135 and #139 are 20-amp fuses for USB power.
Fuse #58 is a 5-amp fuse for the smart charging module.
If only USB ports are dead, check these fuses instead of the cigarette lighter fuse.
Inspect the Socket for Damage
If the fuse is good but the outlet still doesn’t work, the problem may be physical damage to the socket itself or the wiring connected to it.
Look for Burn Marks or Melting
Remove any device from the socket and inspect the interior carefully.
Look for charring, discoloration, or melted plastic inside the socket.
Check for a loose or wobbly fit when plugging in a device.
Verify whether the LED light illuminates when the ignition is on.
These signs point to overheating from a faulty accessory or an internal short circuit.
Check the Back of the Socket
You may need to remove the center console or dash panel to access the wiring behind the socket.
Disconnect the negative battery terminal first for safety.
Unplug the harness from the back of the socket.
Inspect for burnt or corroded metal pins, loose or disconnected wires, or moisture or debris in the connector.
If any damage is found, replace the entire socket assembly. Available from Ford dealers or aftermarket suppliers.
Test for Power with a Multimeter
A multimeter gives a definitive answer about whether power is reaching the socket.
Set Up and Test Voltage
Turn the ignition to ON.
Set your multimeter to DC voltage in the 20-volt range.
Insert the red probe into the socket’s center contact.
Press the black probe against the metal outer edge as a ground.
Expect a reading of 12 to 14 volts. No voltage indicates a fuse or wiring issue. Voltage present means the socket or your device is faulty.
Test at the fuse slot as well by placing probes on the metal tabs. If power reaches the fuse but not the socket, there’s a wiring break between them.
Prevent Future Failures
A blown fuse once is an isolated incident. Blown fuses repeatedly mean you need to change how you use the outlets.
Avoid Overloading the Circuit
The 20-amp fuse supports up to 240 watts theoretically, but safe use is 120 to 150 watts maximum.
Safe devices include phone chargers, GPS units, and dash cams.
Risky devices include 300-watt inverters and high-draw compressors.
Never plug in damaged cables, frayed wires, or cheap no-name adapters.
Consider using a surge-protected power strip or inverter with built-in overload protection.
Keep Outlets Clean and Dry
Blow out dust with compressed air every few months.
Never place coins, keys, or metal objects near the socket, as they can short the circuit.
Use rubber caps on unused outlets to block moisture and debris.
Carry Spare Fuses
Keep 2 to 3 spare 20-amp mini blade fuses in your glove box.
Most F-150s include spare fuses in the fuse box itself. Check under the cover.
When to Seek Professional Help
If you’ve replaced the fuse, checked all outlets, and tested for power but the cigarette lighter still doesn’t work, it’s time for deeper diagnostics.
Signs of a Wiring Fault
Watch for these warning signs that indicate a more serious problem.
Fuse blows immediately after replacement is a sign of a short circuit.
Burning smell from the dash or console indicates overheating wiring.
Intermittent power that works sometimes suggests a loose connection.
Multiple electrical issues in the cabin point to a broader system problem.
These symptoms suggest a short circuit, grounding fault, or damaged harness that requires a certified technician.
Consider Socket Replacement
If the socket is melted, loose, or doesn’t hold plugs securely, replacement is the only fix.
The part costs $20 to $50, and labor costs $75 to 150 if done at a shop.
DIY difficulty is moderate, as it requires interior trim removal.
Aftermarket sockets are widely available, but ensure 12-volt compatibility and correct fit for your model year.
Frequently Asked Questions About Ford F150 Cigarette Lighter Issues
Why does my Ford F150 cigarette lighter stop working suddenly
The most common cause is a blown 20-amp fuse. This typically happens due to a faulty device plugged into the socket, overloading the circuit, or a short circuit from damaged accessories.
Where is the cigarette lighter fuse on a 2009 Ford F150
For 2009 through 2014 models, the cigarette lighter fuse is #22, located in the passenger-side interior footwell fuse box. It’s a 20-amp yellow fuse.
Can I use a higher amp fuse to prevent blowing
Never replace a 20-amp fuse with a higher rating. This defeats the circuit protection and can cause wiring damage or fire risk. Always use the correct 20-amp mini blade fuse.
Why do multiple outlets in my F-150 not work
Later model F-150s have separate fuses for different outlets. Check the front outlet fuse, center console fuse, and rear outlet fuse individually to identify which circuit is affected.
How do I know if the socket itself is damaged
Inspect the socket for charring, melting, or discoloration. If the fuse is good but there’s no power at the socket, or if plugs feel loose, the socket likely needs replacement.
Is the cigarette lighter fuse the same as the power outlet fuse
Yes, in Ford F-150s, the cigarette lighter and power outlet are the same 12-volt circuit. Later models may label it as a power outlet, but it functions identically.
