"Current" Affairs (Blown Fuses)

September 6, 2020

You may be driving along and find that suddenly your radio stops working.  There are no numbers on the display.  Then when you get home, you notice the garage door opener doesn't do a thing when you press the button. Hmm, this was working just fine this morning.  Are the two problems somehow related?

 

No, your vehicle doesn't need an exorcism. This has all the signs of an electrical issue, and when you experience symptoms like those, you've probably blown a fuse.  Most vehicles have fuses just like most houses have circuit breakers (some houses still have fuses). They cut the power when it reaches a pre-determined threshold that could cause major damage if it was allowed to continue.  You might say fuses take one for the team.

Most modern automotive fuses are plastic with a thin strip of metal in them designed to melt when a calibrated amount of power passes through.  The philosophy is it's better for an inexpensive fuse to be destroyed than your sound system or your engine's main computer.

It can be tricky to figure out what fuse has blown and why.  Modern vehicles have many computerized electronic components; they can easily be damaged if too much electricity gets to the wrong spot.  At Tuffy TIre & Auto Service Center Orland Park in Orland Park, we have technicians trained to trace which fuse has blown and why.

While sometimes a simple fuse replacement will fix the problem, other times there may be some other electrical component that has failed, causing the circuit overload.  Our technicians have special equipment to track down where the power problems are, get to the root of the problem and fix it at the source.

Keep in mind, fuses are there to protect your vehicle. And when they shut down your radio, garage door opener, vanity mirror or anything else, just be thankful they're doing their job. They may have saved you from a much more expensive repair. They've sent an important signal to you about your electrical system.  That's why it's good to keep up with "current" affairs.
