Why Dome Lights And Radio Not Working?

I was driving my car to work this morning and while listening to my favourite radio station, the car headlights started blinking. Soon the radio went off. When I parked my car in a parking lot near work, I realised that my license plate wasn’t working either. However, if you are having issues with your dome lights and radio not working, try these troubleshooting tips to fix it.

Reasons Why Dome Lights And Radio Not Working?

Here take a look at few reasons by which dome lights and radio not working:

1. Blew Fuse

One of the most common reasons why some lights and radios not working is a blown fuse. However, if the radio itself does not turn on, the problem is most likely caused by one or more blown fuses. This should be verified by checking the power and grounding of the radio with a voltmeter and making sure the fuse is blown.

All other interior lights work perfectly, but headlights and radio do not. This is a good hint that the root cause is something all lights have in common. In the extreme case, it will be a fuse, so a check is necessary.

Depending on the vehicle configuration, the fuse box may be located inside or near the glove box, under the dash or in the engine compartment. You can usually search the internet for pictures of the location of the same fuse box. The fuse you are looking for is usually a “headlight” fuse, but it may vary from vehicle to vehicle. The only way to know for sure is to find a wiring diagram.

2. Wiring Short

However, it works intermittently or does not work. A short circuit in one (or more than one) of the cables causes the dome lights and radio to not work. You can even blow a fuse in a fire race. It’s technically possible for a fuse to blow without any other problems, but it’s not very common. In the extreme case, if the internal lighting fuse blows, it means there is some kind of short circuit in the system.

It could be an endless failure or it could be a temporary one, but the only way to know for sure is to replace the fuse and see what happens. But this means you are dealing with a paragraph. If you are replacing the inside of the burnt, ignite the fuse and it will blow again. It may still be a commodity you can handle yourself, but some films will bear the attention of a professional technician. However, or into sun bills, and can’t find the short, If you check all the cables where they pass through into your doors.

3. Damaged Antenna

Still, the radio itself doesn’t, also the Problem most probably lies with either the antenna or the tuner, If the auto’s CD player still works. A damaged antenna means that your radio isn’t suitable to admit signals from the station’s damaged tuner means that the head unit itself will most likely need to be replaced.

4. Bad Door Switch and Room Lighting

The last point of failure that can affect all interior lights at the same time is a bad door switch. This switch can be installed on the door frame of an external bus. Therefore, it is often used as a door jam switch.

When a car’s interior lights are working properly, they usually turn on when you open the door and eventually turn off when you close the door. This process depends on a door jam switch that opens when the door is opened and closes when the door is closed. This switch is often covered with a rubber cover that can be lifted with a flat head screwdriver.

The controller can also tighten or loosen screws. However, if you have a multimeter, you can test the switch by connecting it to two external stations and testing its strength. You can also switch it on and check again. But if the readings don’t change, the management is terrible.

5. Damaged Speaker Cable

But no sound (or only one or two speakers). If the car radio is on, the intruder has most likely damaged the speaker lines. They run through the cabin, connecting each speaker to a head unit (or amplifier).

Frequently Asked Questions

Let’s take a look below at some frequently asked questions:

You have a short in the wire going to the brake light. It may have gotten caught on something in the trunk and the insulation ripped off, or your brake light socket is shorted or the bulb is shorted.

Likely either a switch is turned to the on position or activated by action such as opening a door, etc.. or there is a faulty switch.


Separate switches control the car’s lighting and radio systems, but they can be linked together. This allows you to turn on room lights while the radio is on and vice versa. However, you should check the wiring for damage or erosion that could make the dome lights and radio not working. So, continue to analyse our vehicle’s good maintenance checks.
