If your dashboard isn't working right, like when you notice the lights flickering or certain gauges not turning on at all, you can try checking the fuses. Blown fuses for any one of the dashboard gauges can cause these issues. Therefore, instead of having to shell out for a pricey new dashboard, you can simply swap out burnt fuses. However, you'll first have to locate the fuses that specifically control the dashboard gauges. This does vary from one car to another, so it's a good idea to check the owner's manual to see which is which. For example, in an old Honda Civic, fuse no. 15 and 19 are known to cause some or all dashboard gauges (or the lights) to stop working if they blow out. This will differ in your car though, so you should refer to the fusebox diagram.
