The Ford F-150 is the best-selling pickup truck in the US and has been consistently popular in North America for many decades.
One of the things people like most about this truck is the sheer number of engine options that are available for it.
As well as for its looks, interior, towing, and payload capacity.
This article explains the “Top 7 Ford F-150 Features Not Working”…
Ford F-150 110V Outlet Not Working
If your 110V outlet is completely dead and unresponsive, then the most likely culprit to this problem is a blown fuse.
You can likely check the fuse box and simply replace it with one of the spares already in the fuse box and avoid any fees altogether.
The more common issue with the 100V outlet, however, seems to be intermittent power loss, especially when driving the truck.
The two components that need checking are the inverter and the electrical connections.
Replacing the outlet entirely is quite cheap and straightforward. There are no screws or bolts holding it in place. It just clips in.
You can remove the old outlet and replace it with a new one that might cost as little as $10.
If you took it to a dealership to do, they may charge an additional $20-40 for labor depending on their hourly rate.
Fixing the inverter or connections is not something recommended to do yourself since it involves critical electrical components.
A professional fix of the inverter or connectors may cost between $50 and 70, with most of that cost going on labor.
Ford F-150 Trailer Lights Not Working
If you have just bought the truck, it’s quite possible that the dealership did not install the particular fuse that you need to control the trailer lights, but it will be in your truck.
You don’t need to spend any money on this, it’s quite simple.
Check the rear door pocket or your glove box for a plastic bag with small spare parts. You’ll likely find it in there.
Put that in place in the fuse box under the hood and it should start them up.
If your trailer lights were working previously but no longer, then check specifically fuse number 67 to see if it has blown. This is the fuse that controls the running lights.
If this fuse is blown, your turn signals and brake lights might be working, but the running lights may not be.
If fuse number 67 appears to be alright, double-check fuse 73 as well. That’s another one that’s linked to your trailer lights.
To have this checked and dealt with at the Ford Dealership would just cost between $50 and $70, mostly for labor. The cost for this type of problem is negligible.
Ford F-150 Interior Lights Not Working
If when you open your F-150 doors the interior light is not turning on automatically as it should, then the first thing you should do is check relay number 1 under the dashboard.
Replace it with another of the same size ($5-10) to see if it makes a difference.
If you can, you should also open up the plastic cover and see if there are any visible signs of damage like burns or bulb blowouts.
Switches may also have become corroded; in which case you might treat them with some WD-40.
A new dome light will only cost between $8 and $15, and with labor to replace it the total cost comes to $35-50 in total.
Ford F-150 Lane Assist Not Working
The two most common reasons for your F-150 Lane Assist feature not working are a wiring harness not being connected up properly or a problem with the switch.
If the wiring harness has become disconnected, this problem can be fiddly but not complex to fix and you might spend up to $100 to get it sorted.
The real issues come when a dealership or other repair outfit identifies the button as the main problem.
You might think the button being a problem would be a small fix, and even better, the button is under warranty.
The issues arise when repairing the button and the dealership points out that major parts of the console also need replacing, which can cost as much as $950 and is not covered by your warranty.
With some help from a how-to video, you might save on these costs by learning to pop open the console yourself and locate the switch to repair it.
One more possible fix is to ensure that the F-150 is set to “Aid Mode” in the IPC settings. Without it, the system appears unresponsive, but once turned on it should come to life.
Ford F-150 Daytime Running Lights Not Working
The first thing to note with this problem is that you need to be sure your daytime running lights (DRLs) are really not working, or whether they are just on but you don’t realize it.
A mistake that some people make is that they assume the DRLs will display as a green light on the dash in the same way as the headlights do. In fact, this is not the case.
The F-150 doesn’t feature any indication light that the DRLs are on, and they only appear when the car is in “Drive.”
Therefore, you could have a friend or neighbor check to see if they’re on and let you know.
You could also check them in the reflection of a car in front or a building that you are parking in front of.
However, if they really are broken or not working, then the problem is most likely a wiring issue or a problem with the DRL relay.
As with many electric issues, it’s also worth having a look at the fuse box to see if there are blown fuses that might explain why suddenly they have stopped working.
To get the lights fixed professionally, it could cost up to $80 in parts if it’s a problem with the lights themselves, and an additional $50 in labor.
If it’s just a fuse or wiring problem, that cost might come down somewhat, but labor might remain about the same.
Ford F-150 Microphone Not Working
If you find that the sync microphone in your Ford F-150 is not working, then the first thing you might try is performing a master reset on the system to see if that helps before you do anything else.
If that doesn’t help, check the fuse box under the dash on the passenger’s side and inspect fuse number 2.
If that appears blown or otherwise damaged, that could be the issue. If it is the fuse, you could replace it with a spare in the truck for no cost.
One other issue some have discovered upon trying to replace the microphone entirely with an aftermarket alternative or a replacement original part is that there is sometimes insufficient insulation around the wiring.
That would definitely make it faulty.
You might check on that before getting a replacement, but in any event, a replacement can be as cheap as $15 and if you know where to look:
— The little square grille in the headliner between the sun visors on older models, and between the two lights in the overhead console on newer generations. —
You can try to replace the component with easy instructions or to have it done professionally, it would cost you about $45 with parts and labor.
Ford F-150 Fuel Gauge Not Working
The fuel gauge not working properly is a big problem because it means you aren’t getting an accurate reading on gasoline levels.
You could end up breaking down because you’re never sure how much fuel you have.
As with so many problems in modern cars, the first place to look is the fuse box. For the fuel gauge, you need to check the fuse panel under the hood on the driver’s side.
Replace any blown fuses and see if it comes back to life.
The next thing to consider would be the bimetallic strips and wiring connected to the gauge.
If the wiring is frayed or otherwise damaged, then that could be causing it not to work. If all these components seem in order, then the problem is more serious.
The first problems are likely to be solvable with DIY methods if you have confidence and some know-how and at negligible or no cost.
The alternative, however, is more serious and likely involves the sender unit in the fuel tank.
Replacing the sender unit is tricky because you have to drop the fuel tank. It needs emptying, the lines disconnecting, and removing to get to the sender unit.
The sender unit is an expensive part, as much as $720. If you factor in about $200 of labor cost, then you’re looking at total repair costs of $920 or more.
If you have experience and can do it yourself, then you can save yourself $200, but otherwise, seek a professional to do this.
The fuel system is sensitive and too critical to the overall truck operation.
