Two instrument panel lights are not working

I have a FAW V2 (I selected Fiat as there are no FAW option), and it seems like 2 lights on the instrument panel are not working. The one is the low fuel warning, and the other is the seatbelt warning (driver & passenger) light. The car is barely a year old, so I doubt that it is a bulb that is blown. Can it possibly be a fuse? Or a sensor? Any info will be much appreciated. Thanks

My car has 18000 miles.
My car has a manual transmission.

Experienced mechanics share their insights in answering this question :
If a sensor has failed for the seatbelt light, then the light will come on. If the low fuel warning light does not come on, it indicates that either the vehicle was not driven long enough to make the light come on, or that the sensor on the fuel pump has failed.

For the fuel warning light, check the wiring between the fuel pump level sensor and the dashboard for resistance. If there is resistance, then the sensor is working. If there is no resistance, then the sensor has failed and the unit in the fuel tank needs to be replaced. If the sensor is working and there are no blown fuses, then check for any loose or broken ground wires under the dash.

For the seatbelt, check for any fuses that are blown. If there are no blown fuses, then the sensor may have looped itself and caused the computer to think that the belt is connected.

It is recommended that you change the seatbelt sensor for both the front seats. If you need further assistance in troubleshooting your vehicle, then seek out a certified technician, such as one from YourMechanic, to inspect your vehicle and check why the lights are not coming on.

How the low fuel gauge actually works. Details vary, but most cars have a float in the gas tank. This is connected to a lever and “sender` that puts out an electrical signal. That drives the gauge, and when it reaches a certain level it also turns on the low fuel light.
A light that looks like a gas pump indicates that your fuel level is low and you should get gas as soon as possible. Please note that driving with low fuel levels can damage your fuel pump and other fuel components in your car`s fuel system.
The low fuel warning light will show up on your dashboard when the fuel when your car`s tank reaches a certain level. It is there to inform drivers that they are critically low on fuel and will need to get to a petrol station and put some more in the tank as soon as possible.
The switch will usually come with a reset button that will reactivate the fuel pump if the switch was tripped. The fuel pump switch is an electrical component, and just the same as the rest on the vehicle, over time it can wear out and develop issues.
Pressure Sensor: The most common type of pressure sensors used for fuel level measurements is hydrostatic type sensor.
The gas gauge is very easy to read. All you need to do is look at the needle`s position on the gauge. The closer it is to F, the fuller your gas tank is. On the other hand, the closer the needle gets to E, the more empty your tank is.
If water accumulates in the fuel filter, the warning light comes on when the ignition switch is in the ON position. If this warning light illuminates, take your car to a professional workshop and have drain the water and check the system.
The fuel pump shut-off switch has a red reset button on top of it.
1. Turn the ignition switch to position `0`. 2. Press down the rubber reset button on the top of the inertia switch.
The throttle position sensor (TPS) is usually connected to the throttle plate shaft in the throttle body. The TPS reads the angle of the throttle valve and transmits an electrical signal to the PCM. The PCM uses this real-time signal to help calculate or modify fuel injector pulse width, controlling air/fuel mixture.
The basic operating system for an electric fuel pump is relatively simple. When the key is turned on, the powertrain control module (PCM) closes the fuel pump relay, which activates the fuel pump for about three seconds to pressurize the fuel injectors.
Fuel quantity gauges are necessary so that the operator may know the quantity of fuel remaining in the tanks during operation of the aircraft. The four general types of fuel gauges are: (1) Sight glass, (2) mechanical, (3) electrical, and (4) electronic.
“Typically, it will light up when the tank is below 10% to 15% of its capacity.” In general, after the gas light comes on, Muñoz says it`s safe to drive about 20 to 30 miles in a smaller vehicle or up to 50 miles in a larger vehicle.
Particularly if you are experiencing an issue with more than one gauge on your vehicle, the culprit may be a fuse. If the fuse for the instrument panel has been blown, make sure to replace it. Then go ahead and turn on the car. If the fuel gauge doesn`t sort itself out automatically, run the cluster test again.

Damage to your fuel pump

The fuel pump is designed to function with a certain amount of fuel. Driving with low fuel can damage the fuel pump because the fuel cools and lubricates the pump as it flows. If you run your car low on gas, the pump will start to draw air in place of some of the fuel.

Two instrument panel lights are not working – the fuel warning light and the seatbelt warning light.
ANSWER : If a sensor has failed for the seatbelt light, then the light will come on. If the low fuel warning light does not come on, it indicates that either the vehicle was not driven long enough to make the light come on, or that the sensor on the fuel pump has failed.

For the fuel warning light, check the wiring between the fuel pump level sensor and the dashboard for resistance. If there is resistance, then the sensor is working. If there is no resistance, then the sensor has failed and the unit in the fuel tank needs to be replaced. If the sensor is working and there are no blown fuses, then check for any loose or broken ground wires under the dash.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.

All dashboard lights and tail lights do not work after driving through a lot of snow. Headlights work. And brake lights work.
ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

No tail light, instrument panel light, or tag light
ANSWER : Hi there, thanks for writing in. Most ancillary electrical items (like tail lights, instrument panel lights and tag lights) are actually controlled through an electrical relay box. On your Ford Expedition, there is usually a main relay control box and a secondary relay box. If any part of the relay is damaged, it will cause items like you’ve described to all fail. The best way to determine exactly whether this is the case or source of your problem, is to contact one of our local mechanics to complete an electrical inspection. This should pinpoint the source of your issues so that the corrective action can be provided.

Dash, Tail/brake, dome, trunk, glovebox, and door lights won’t work, dash doing weird things.
ANSWER : Hi there. Sure would appear a lot is going on electrically all at once. This could be, a problem in the PDC (power distribution center). The PDC is typically located under the hood and contains numerous fuses and relays. I don’t believe any one fuse will resolve all of the electrical issues. There is a possibility, it is not a power supply issue. It may be, the result of a poor electrical ground common to the inoperative components. Proper circuit testing should be performed. This would confirm the cause of multiple electrical failures. I recommend having your vehicle’s electrical problems be diagnosed and repaired by a certified technician, such as one from YourMechanic.

My dash board don’t work my front light work when I change my light into high beam and my back window won’t go down
ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.

signals, daytime running lights are not working, park brake light on dash is on steady and chime is dinging steady 4×4 wont engage
ANSWER : This is likely a brake light switch problem. I would suggest testing the brake light switch which should be located down by the brake pedal. This may also be a computer problem as well as indicated by the other lights on in the dash. I would recommend having an expert from YourMechanic come to your home to possibly replace the brake light switch and diagnose with a scanning tool which will download useful data from the truck’s computer indicating what specifically the problem may be.
