Blowing the fuse? Let us help you!

Have one of your car’s fuses blown?

Something will usually stop working to indicate that a fuse has blown. For example, it may be the turn signals, your backup lights or some other electrically-powered item.  The solution is replacement of the faulty fuse.

During the course of owning a vehicle, there’s a chance that a fuse will blow out.  You will know when this occurs because a device or component in your car won’t work, like in your house when you all the sudden can’t turn on a light and figure out the plug is the problem.  Engineers make cars like this to prevent potential engine fires.This is what the Sales Manager at Suburban Chrysler Dodge Jeep RAM of Farmington Hills, a full-service car dealer in Farmington Hills, MI, tells us.

Two Fuse Types

In general, many cars have two types of fuses. Older vehicles have glass, tube-like fuses with glass in the middle and stainless steel caps on the ends.  These types of fuses were common a couple of decades ago and are rare now in vehicles.  Today’s vehicles have an interesting style of fuse that uses a colored plastic housing with the fusible link encased in the housing. You should do an internet search for these two different types of fuses to see pictures of them. They really are interesting!

Identifying the Problem Fuse

If you think a fuse might be the problem when something stops functioning, the first step is to locate the fuse and see if it is blown. Now, we realize that this might be trick. However, your owner’s manual can help you find your fuse box and once you have found it, you have to determine which fuse needs to be removed for inspection.

Say, for example, your interior lights don’t illuminate. The owner’s manual will usually have a chart to show you which fuse protects your interior lights.  Once the fuse is identified, you have to see if it has failed. This is usually easy.  If the metal link inside the fuse is separated, the fuse is “blown”.  If not, then it’s still good and can be reinstalled. 

Is a Replacement Needed?

If a fuse is blown, the next step is locating a replacement. Some cars come with a spare supply; otherwise you will need to make a quick trip to the auto parts store to purchase some. The most important element to fuse replacement is using the same amperage rating as the blown fuse. If you examine the fuse’s top, you’ll see a number.  That is the fuse’s Amperage Rating.  We recommend always keeping some extra fuses in your glove box!

A Brief Explanation of how to Put in a New Fuse

So, once you determine the fuse has blown and have received a suitable replacement, it is time to reinstall the new one. Don’t worry, as it is quite a simple process. But you may head to the garage if that makes you more comfortable. Putting the new fuse in is the easiest part although sometimes a fuse puller (often provided in the fuse box) will help you. Put in the new fuse, start the vehicle and see if the new device works.  If it doesn’t you likely have other problems to solve as well and it might be best to have a certified mechanic look at it for sure.
