Why Is My Dome Lights And Radio Not Working? [Easy Fix]

While night driving we all tend to vibe on our radio but what if it stops working in the middle you stop your car and find the dome light isn’t working or your mind starts rumbling why are your dome lights and radio not working. In this post, we will know what causes this problem and how to fix it.

In most the vehicles it is caused due to malfunction in wiring or the fuse has been shot which caused them to work no more-

Why Is My Dome Lights And Radio Not Working?

It’s most likely a fuse. A fuse box is located on the far right side of the dashboard. Open the front passenger door to see a fuses cover at the end of the dash.

1. Checking FuseBox

A fuse box is also positioned beneath the hood, to the right of the engine compartment. Before checking the fusebox we recommend you to check the owner’s manual which will clarify the fuses. The fuse you’re looking for is usually the “lights” fuse, however, this can vary from vehicle to vehicle. The only way to be certain is to acquire a wiring diagram for your vehicle’s precise make, model, and year, but testing all of the fuses labeled “lights”

2. Checking Fuses and Relays

Although looking at a fuse normally indicates that it is blown, this is not always the case. ┬áthe only way to check them is using a tool such as a multimeter. If you use a multimeter and discover no continuity between the terminals of a fuse, it’s blown which may have to lead the dome lights and radio not working

3. Checking Wirings

There is a short somewhere in the system. It could be a permanent or temporary flaw.
When you replace a blown interior light fuse and it blows again, you have a short circuit. Most shorts can be traced back to spots where wires habitually bend and crimp, so that’s the best place to start.

How To Fix Light And Radio Issues?

Finding and changing a fuse is not a hectic task, you just need your old handy pliers, a multimeter

1. Changing Fuses

Step 1:

Park the car.

Set the parking brake.

Step 2:

Locate the fuse panel. This is usually on the driver’s side of the dashboard or beneath the hood in the engine compartment. Determine the location of your fuse block by consulting your vehicle’s owner’s manual.

Step 3:

Examine the fuse diagram. Refer to the owner’s manual or the schematic on the reverse side of the fuse block lid to locate the radio fuse and amperage rating (15, 20, 25, or 30 amp fuses).

Step 4:

Disconnect the fuse. Using the fuse puller, hold the suspected blown fuse (in this case, the radio fuse) and pull it straight out of the fuse block.

Step 5:

Change the fuse. Insert a new fuse of the same color and amperage rating into the slot from which the blown radio fuse was removed. To confirm that the problem has been rectified, turn the key to the accessory position and turn on your radio. By changing the fuses it may fix the problem which caused dome lights and radio not to working

2. Checking And Fixing Wirings

  1. If you have an aftermarket radio, check the wires. This exact problem will occur if you have switched power on the radio (red) on an aftermarket deck. Sometimes there is an illumination wire on the car that reads the same as a switched power wire but it is the illumination. However, the radio and dome light are sometimes on the same fuse, especially if it is hooked to the illumination wire instead of the switched power.
  2. In any case, double-check all of the head unit connections. A wire may have been pinched, a solder may have broken, a piece of tape may have come loose, or the insulation on a wire may have worn off. While you’re at it, double-check the inline fuses and grounds.
  3. Please double-check that your IOD (install-on-delivery) fuses are completely installed; they can wiggle loose and eliminate power to your radio, interior lighting, and clock.
    They are two fuses held together in a single carrier (typically yellow) in the under-hood fuse box; insert your tiny finger into the carrier to press directly on the two fuses inside.fuseIf this has no impact, remove the carrier and check the fuses. To clear it past its tabs, the carrier will draw out with a light rocking action. Once it’s removed, use needle-nose pliers to remove the fuses.
  4. DOME is the name of the fuse. and powers the doom and any active overhead doors. There are five lamps in total: luggage, dome, and personal.
  5. If the main light is out, it signifies the lamp has failed or the DOME fuse has blown. The fuse will contain 12V on both sides, one side will be connected directly to the battery’s main fuse. When I open the OEM page, the clock and radio memory both receive power from the DOME fuse.

Conclusion

As previously noted, if dome lights and radio not working look for wirings that are powered by the same electrical connector. If you want to track down the source of the problem, you’ll need a wiring schematic and a multimeter. If it’s not the fuse, I believe you’ll have to look by hand. Although replacing a fuse is reasonably simple, it is critical to replace it with the correct style and amperage rating. Although automotive fuses are generally straightforward to recognize on sight, a visual reference can help you establish the sort of fuse you want.

If you replace a fuse and it blows again, there is usually an underlying issue. Replacing the fuse with a higher amperage fuse may temporarily solve the problem.
