Car lights are very useful for many things. Dome-shaped lights, which are usually located above the dashboard, are designed to give the driver a sense of security when driving at night. Map lighting is typically located near the rear windshield and helps drivers see better when using the maps; they also help drivers see better when turning on their heads-up displays to navigate.

The instruments are bright enough to allow drivers in the dark to see the gauges clearly and also to help prevent glare from damaging the eyes. You can have your Chevy Blazer’s interior lights work properly, but sometimes they will stop working. This happens for a variety of reasons.

Symptoms of Chevy Blazer Interior Lights Not Working

If your Chevy Blazer’s interior lights are not working, you may notice one or more of the following symptoms:

How to Fix Chevy Blazer Interior Lights Not Working

Check the Dome Light

Dome lights, which are the easiest to replace, are usually the ones that cause your car to be unable to turn on. If someone else is using a dome or a dimmer to turn the interior light on or off, the problem with the lights could be that another person is using the lights to turn it off. It’s also possible that when you open the door, the interior lights will not turn on.

There are several ways the interior lights can be controlled, so you might have to manually toggle them to turn them on. You could try turning the dummy switch in the center of the steering wheel by turning the handle. If that doesn’t work, it means that the dummy switch itself is failing.

You may be able to test this by using a dome light or other lights with the correct switches and then adjusting the dimmer at different locations. You could be experiencing a real line failure if all of your lights keep turning off.

Check for Any Blown Fuses & Light Bulbs

A blown fuse may be the cause of the issue if you find that all the interior lights are out but the radio or audio is still operational. You must gain access to the fuse box, which, depending on the model, is either in the engine compartment or under the dashboard.

The best approach to determine whether a light fuse has already blown is to use a gadget like a test light or a multimeter. If a fuse blows, you must replace it with another of the same kind to avoid damaging the wiring of the vehicle.

Check the Wires

A short circuit is most likely to blame if you’ve already replaced a blown fuse with a new one and it still blows. The ideal places to start checking are the lights located in the door or the map lights beneath the sun visor since shorts can typically be traced back to regions where wires are regularly crimped or bent, shredding the insulation and exposing the copper material. The best course of action is typically to call in an electrician because short circuits are not always visible to the naked eye.
