Dash Light Symptoms & What They Could Mean - Service Information in Salt Lake City, UT

Your dashboard contains a multitude of important information. The gauge cluster lets you know how fast you're going, how much gas you have left, whether something's wrong that needs your attention, and much more! So, dash lights that aren't working the way they should can be dangerous. At Nate Wade Subaru, we want to help you learn more about your vehicle, which is why we've put this page together. You'll find different potential causes of dash light problems below along with some associated symptoms that can help point you in the right direction.

A blown fuse could cause all of the dash lights to stop working 

4. The Dash Is Completely Dark

If the dash is completely dark, the first thing to do is to see if the fuse has blown. Check the owner's manual to find out which fuse corresponds to the dash lights. Then, make sure the vehicle is turned off and the key is out of the ignition. Open up the fuse box, and use the puller to remove the right fuse. Hold it up to a light source to check the wire inside. If it's broken, replace the fuse with a new one of the same size and amperage. If the fuse burns out again quickly, your car may have a wiring problem. And, if all electrical components have stopped working, the alternator, battery, or other electrical system problem may be to blame.

 
If the headlights are on, the dash lights may be dimmer 

3. The Dash Lights Are Dim

The dimmer switch inside your vehicle serves to adjust the light levels of your dash lights. If you've accidentally bumped the switch, it may cause the lights to become too dim. Finding the switch and adjusting it may solve your problems. Or, your headlights might be on without your knowing it. When headlights are on, the dash lights usually dim.

2. The Dash Is Only Partly Lit

Nowadays, many dash lights are individual LEDs that should last for the life of the vehicle. But older vehicles had dashboards that were backlit by a few light bulbs. If one of these burns out, the part of the dash that was illuminated by that light will go dark. If this happens, we recommend taking your Subaru to a service center to have the bulb replaced. This will likely involve removing the entire gauge cluster form the dash, and this is the kind of job that's usually best left to experts like the factory-trained technicians in our dealership service center.

A bad alternator could cause the dash lights to flicker 

1. The Dash Lights Are Flickering

The alternator recharges the battery as your Subaru drives, but that's not all that it does. It also runs the electrical components of your vehicle, including the dash lights. If the lights flicker, it may be a sign that the alternator isn't working as it should. This may also affect other electrical systems like the headlights and the radio. It may even mean that the battery isn't getting enough charge, making it so that your Subaru won't start easily. If this happens, bring your Subaru to the dealership for a new alternator.
