Experienced mechanics share their insights in answering this question :
Fuses are placed in electrical circuits to protect against a situation where too much current flows through the wires or components on the fused circuit. If there’s too much current flowing, due say to a short circuit, that could destroy the electrical components on that circuit and/or cause a fire. Usually, when a fuse blows, it means there’s something wrong in the circuit that needs to be repaired. Consequently, merely replacing the fuse doesn’t solve the problem because if the fault (often a short circuit) has not been repaired, once the circuit is re-powered with a new fuse the new fuse will just blow again immediately. To resolve this issue, your best bet is to request an electrical diagnostic and a certified Mechanic from YourMechanic will come to your location and identify the fault in the circuit that is causing the fuse to repeatedly blow.

A Short Circuit in the Electrical System:

A short happens when there is a poor connection between two conductors supplying electricity, which then causes an overload to the circuit. This overload causes the fuse to blow to prevent the wiring from overheating and melting.

if you`ve replaced your fuse, have double checked the amperage and circuit, and your fuse blows again or your electrical components don`t work, it may be because your vehicle is short circuiting. There are a 2 common factors that cause short circuits: Malfunction. Your windshield wipers, power windows, etc.
Use your owner`s manual to find out where the fuses for your dashboard are located. The instrument panel fuse box is usually located inside the vehicle, and usually on the driver`s side. There should be a diagram inside the fuse box (or in the owner`s manual) that shows you what each fuse powers.
The instrument cluster fuse, also known as the dashboard fuse, powers the gauges and displays on your vehicle`s dashboard. This includes the speedometer, tachometer, fuel gauge, and temperature gauge. If this fuse is damaged or blown, it can cause these gauges to stop working or malfunction.
Improper modification is one of the most commonly seen problems. The most common of these is tapping more than one conductor from a single connection point.
The most common reason for a fuse to blow is when the circuit becomes overwhelmed. You might cause your circuit breaker to trip or a fuse to blow when too many appliances are plugged in at one time. The hair dryer, vacuum, and microwave are common appliances that can suddenly use a high amount of energy.
Inside the fuse, there is a metal ribbon through which all the current on the circuit passes. The ribbon is sized to match the circuit wire gauge, and if too much current passes through the ribbon, it melts through, or “blows,” and the circuit goes dead.
Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
informal. : to become very angry or upset. The boss blew a fuse when the shipment didn`t arrive on time.
If the dashboard isn`t lighting up at all, your car might have blown a fuse. Removing the old fuse and replacing it should get the lights working again. While the new fuse may do the trick, it could also indicate a deeper electrical problem.
If your dashboard lights aren`t working, find the fuse associated with your dashboard lights and check inside. If the fuse has blown, replacing it may be all you need to do to fix the problem.
Most vehicles have a dashboard light control switch that will dim the dashboard lights as well as turn them off. Find the control switch, dial, or knob, which is generally located on the console near the steering column or may be part of the headlight switch.
Most modern vehicles have a fuse box located under the hood and another under the dashboard. The fuses for your instrument panel lights and the gauge cluster should be located under the dashboard or behind a panel near the driver`s side door.
Regular – these are the standard versions and are also the second-largest type. Maxi – these are the largest size available and are designed for high current applications.
The RAC document FMD [1] provides the following modes and percentages. The fuse fails to open when expected (29.8%); the fuse is slow to open (25.5%); the fuse has opened with no cause given (22.7%); the fuse opened unexpectedly (14.3%) and mechanical failure of the fuse (3.5%). Fuses have a current and voltage rating.
How long does a fuse last? If the fuse does not operate then it will typically last 20 – 30 years as long as it is operating within its design limitations. If it is in a higher cyclic operating temperature i.e. very cold or very hot, then this can reduce its life.
No, not advised. Increasing the fuse rating means in case of a fault, the fuse does not blow out and the wiring which is designed for 20amps may lead to fire 🔥.
The most common car electrical system problems are problems with your car battery, an alternator that isn`t working properly, loose or failed spark plugs, a fatigued solenoid or starter, bad battery cables, electrical fuses that are blown, loose wires, or problems with your ignition switch.
Because expulsion fuses produce little voltage while they arc, they do not significantly affect the magnitude of the voltage dip, only its duration (just as they do not limit the magnitude of the fault, only its duration).
You`ll be fine just removing the fuse. Test the outlets with a meter or plug in a light to make sure the outlet is de-energized. Turn off any appliances and equipment with their “off” buttons before removing the fuse.
If you have an older home, you may have a fuse box instead of a circuit breaker. Fuse boxes are not as common as they once were, but they can still be found in some homes. If you`re not sure whether or not your home has a fuse box, look for a metal box with a handle on the front. Inside, you should see a row of fuses.
You can use a bench test setup, which simulates the car`s electrical system and sensors, to connect your ECU and check its operation. You can also use a software tool, such as an ECU simulator or a diagnostic scanner, to communicate with your ECU and monitor its parameters, codes, and outputs.
Connect the multimeter to the positive and negative terminals of the ECU to measure the voltage. A reading below 12V indicates a potential issue. Connect the multimeter to the positive and negative terminals of the ECU to measure the resistance. A reading above 5 Ohms indicates a potential issue.
In the majority of cases, the faulty ECU can be repaired or reprogrammed, and this type of repair will usually run between £150 to £750, depending on the make and model of your vehicle.

Van keeps blowing fuses, no lights in back work, can’t shift unless key is in certain position
ANSWER : There is a short somewhere, causing the fuse to blown continuously. In your vehicle, power flows from the ignition switch to the transmission range sensor. This sensor needs to be operation in order for the transmission to be moved out of park, as does the ignition switch. Since your headlights always stay on, there is obviously a short somewhere in that circuit. This kind of problem will require firsthand professional diagnosis from a professional. I recommend calling YourMechanic to diagnose and repair this electrical problem since we come to your home or office.

I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.

Car blows ecm run/start fuse after starting and then dies replaced fuse and repeats
ANSWER : Hi there. Typically when this issue occurs, damage will be instant – meaning if it’s going to damage the ECU, replacing the fuses would not help start the vehicle. So, at first glance, I would assume the ECU is OK. What is more likely is that you have an exposed wire somewhere that is causing the fuses to pop. Trying to diagnose these issues can be tricky sometimes, so it might be a good idea to have a professional mechanic complete an electrical problems inspection to isolate why you’re having these issues and recommend the right repairs.

Car starts, dashboard lights flicker, air conditioning shuts off
ANSWER : Hello there, thank you for asking about your 1993 Isuzu Pickup. It sounds like a bad ground in the instrument panel circuit. Looking at the wiring diagram, I see the AC heater control panel and instrument cluster share the same ground, which is designated G200. That is the first place I would start. Electrical diagnosis and repair can be tricky, so I suggest you have a professional look into this for you. A certified technician from YourMechanic can inspect your car’s electrical problems and make the necessary repairs.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.
