Hello. As of lately, the dashboard in my car would randomly show warning lights on and off. The lights would come on and off again if I turned off the ignition. This occurs both with the open and closed door, but always when the key is not in the ignition. There would also be some beeping noise. This happens occasionally. So, I would then have to start the car up again for this to stop. Besides this, I once had the issue with starting the car. I jumped it. At the shop, they didn't find any issues. They had the batery and alternator checked and it was all fine. What could be the problem her
Hello. Dashboard lights blinking are a common electrical issue with this vehicle. Most of the time, if the battery is fine, it is a connection issue on the negative battery cable ground connections. The connections become corroded or loose and this will occur. If the connections are fine, then it is either a failing ignition switch or main relay. The main relay being the more common of the two. I typically test the relay while it is installed to see if it is opening and closing as it should. If it is not, then it is replaced. If it tests fine, then I perform a voltage drop test of the ignition switch and replace it if needed. If you need to have this checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your dashboard lights.

If the battery isn`t working properly, it could cause the dash lights to flicker. It`s best to have your battery tested at your neighborhood Firestone Complete Auto Care, and install a new battery if necessary. Additionally, flickering dash lights can signify that there is something wrong with the alternator.
Bad Ignition Switch
This switch is what allows electricity from the battery to reach the starter so it can spark and ignite the gas. If it`s gone bad, the dash lights can flicker, the radio and other electrical accessories may not work or you may have difficulty turning the ignition key.
The Dashboard Lights Flicker
If you notice any flickering, be sure to check your battery before you end up stranded. Similar to dimming headlights, these flickering lights are a sure indication of a failing car battery.
Second, if any of the lights are blinking, it generally means that immediate attention is required. Fixing the blinking light can be as simple as fastening your seat belt or making sure a door is fully closed. But if other lights are blinking, urgent repairs or service may be necessary.
This kind of thing can usually be narrowed down to a corroded ground wire or a bad connection between the gauge cluster and the main wiring harness.
Bad bulbs or fuses
If the vehicle battery isn`t the reason for your flickering car lights, you might be looking at a failing light bulb or a bad fuse. Light bulbs are an easy and quick fix and present an opportunity to upgrade to new LED bulbs.
A failing light switch, either the interior dimmer or the headlight switch, should be considered if you have flickering lights on your vehicle. In some rare situations, just replacing a worn switch may solve the problem, especially in vehicles with excessive mileage or older vehicles.
Worn Spark Plugs
There are times when an engine won`t start because a spark plug has worn down and is no longer firing. You may also experience flickering dashboard lights if this is the case.
An early warning sign that your alternator is going bad could be dim, flickering lights. This symptom could show up on any or all of your dashboard lights, reading lights, headlights or other lights. The alternator is supposed to provide the electricity for your car`s lights.
An illuminated battery light could be due to a number of issues, including: A loose or corroded battery cable. A problem with the alternator or voltage regulator. Damaged cells or plates inside the battery.
The check engine light is usually the most serious and feared warning because of the kind of damage it can signal. This warning often indicates the potential for serious engine damage. When ignored, your vehicle could suffer from a blown head gasket or a seized engine.
There are 3 different categories of warning lights; red, amber and green: Red warning lights mean you should stop the car as soon as it`s safe. Yellow warning lights mean that action is required. Green warning lights are for information only.
The instrument cluster fuse, also known as the dashboard fuse, is responsible for powering the dashboard gauges and displays. If this fuse is blown or damaged, it can cause the gauges and displays to stop working or function improperly.
Leave it in the first position. While the key is in the ignition, press and hold the instrument panel reset button located next to the odometer or fuel gauge. While pressing the reset button, turn the headlights on. Then turn the key to the second position but do not start the car.
If the power supply is not working properly, it can cause the LED lights to flicker or blink. This can be caused by a variety of issues, such as a poor wiring, or a faulty or malfunctioning power supply. Another common cause of LED light flicker is a problem with the dimmer switch.
Your alternator powers your vehicle`s spark plugs, the parts that light your gasoline to start your engine. If your alternator is not working, your spark plugs will not be able to function either, leading your car to struggle to start up.
Check Engine Light
If your sparks plugs have gone out, the OBD scanner should read the codes P0300 or P0171 which means lean running engine coupled with misfires. A good way to check spark plugs at home is by doing a thorough visual inspection.
Can You Jumpstart a Car With a Bad Alternator? It`s possible that your car will start even if your alternator is bad, but it will probably stall once the battery runs out of enough power to keep things running the way they should.
If you have a faulty alternator and the vehicle battery gets low on voltage then the computer may not shift the transmission gears correctly and cause other drive symptoms like stalling or surges and rough shifts. Engine and transmission may even go into failure mode and cause various drive symptoms.
Can a Bad Battery Cause Electrical Problems? Yes, if your battery is underperforming it can cause systems within the vehicle to malfunction. A bad battery can also result in air conditioners, stereos and other applications not receiving enough power to function properly.
If any corrosion develops along the battery terminals, this may interfere with the connection and the vehicle may have trouble starting. This can be caused by corroded or even loose battery terminals. The vehicle may experience difficulty starting, slow cranking, or rapid clicking when the key is turned.
If all of your lights have come on then that may be an indicator of some sort of serious malfunction with the vehicle. The fact that it appears to be running fine is a good sign. However, I would refrain from driving it until you can figure out what the issue is.
