How to Fix Car Ignition Switch Problems

If your car is running and starts, but the ignition switch isn't able to turn on the spark plugs, there could be a myriad of reasons for this. Some are easy and cheap to fix, others require specialized tools and assistance from an expert mechanic.

Lubricate the socket before you use it. You can apply graphite powder or silicon spray. Also, make sure the ignition cylinder is free of obstructions and loose springs.

Battery

It could be that your battery is dead if your car won't start. This is a frequent issue that can be resolved by either charging your battery or the jump. If this does not fix the problem the ignition switch could be defective. This component is responsible for transferring power from the battery to other electrical components like the starter motor and ignition coil. If the ignition switch is damaged it will not allow current to flow through and the engine won't begin.

The battery is the source of all the electrical energy that is used in your car. The battery is a black, slender box with positive (+) and negative (-) terminals at the top. The terminals could be corroded and stop the battery from providing electricity to the rest of the vehicle. You can clean the battery's terminals by disconnection of the battery and using a wire brush to remove any corrosion. You can also clean the terminals using baking soda as a solution.

Your car battery may also be at the end of its life and requires replacement. A new battery will supply the proper voltage to your vehicle's spark plugs, which is required for a properly working engine.

The ignition coil is responsible for changing low voltage from the battery into high voltage that will spark the spark plugs in your car to start the engine. If your ignition coil is defective, it will not be able to ignite the plugs. The engine will not start. You can test the ignition coil by checking whether there is a spark in the engine or turning the key and seeing if the engine turns over.

You may have to replace the starter motor too. If you hear a grinding noise when you turn the key in your ignition, it is a sign that the bearings in the starter are starting to wear out. This could be a costly repair, so it's best to replace the starter motor as soon as possible in the event that you notice signs of wear and wear. It's an easy process that requires the replacement of some bolts and parts.

Alternator

The alternator is an instrument that charges your battery while your engine is running. It also is the power source for your car's electrical components. Check the battery first if you suspect that your alternator is malfunctioning. This will allow you to determine whether your alternator is causing your battery to drain or the battery is just old and needs to be replaced.

The alternator in your car also provides power for your dash lights, windshield wipers and power windows, electric steering heated seats, and your radio while the vehicle is idling. You can use a voltage meter to check your battery and the alternator to determine the proper voltage levels. If your battery is less than 6 volts it should be replaced or charged immediately. A low or dead batteries will also prevent the starter from turning the engine over and may require additional jumper cables in order to start your car.

Before you begin removing the alternator, ensure the ignition is off and that all doors are locked. You should also disconnect the negative cable from the battery, tuck it away in a safe place and put on safety gear. Check out a repair manual that is specific to your vehicle for directions on how to remove the alternator, or any other component.

After you've removed the belt, if your car has one, disconnect the warning light wire from the back of the alternator. This wire will usually connect directly to a terminal on the alternator that's marked WL or IND. Some vehicles have an additional relay that performs this function. If your warning light does not appear, it is likely to be an issue with your vehicle.

You should check regularly your alternator for any indications of malfunction. While you could perform some of the tests on your own, it's recommended to bring your vehicle into Les Schwab for a free inspection and expert advice. Our technicians can check for corrosion on your battery posts, battery (+ and Fix Car Ignition +) fuse, relays, and fuses and voltage output and cold starting amps and much more.

Starter Motor

The starter motor is a crucial element of the ignition system. It is responsible for turning over the engine so that it can draw in air, which is essential to ignite the fuel. It is quite common for the starter motor to be the cause when your car doesn't turn. There are many methods of troubleshooting that can be used to assist you in identifying and fixing the problem.

When you turn the key on your vehicle's ignition, a switch in the starter turns on a pinion gear that fits into grooves on the flywheel. The pinion gear turns the flywheel which begins the engine. When you release the key the pinion gear retracts, and disconnects from the flywheel to avoid damage.

There are a myriad of things that can go wrong with the starter motor including an electrical failure in the internal windings, mechanical issues (such as teeth not meshing with the pinion gear or flywheel) or a dead battery. Often, a faulty starter motor can sound like a dead battery. it will make a clicking sound as it tries to turn over the engine, but won't.

If the starter motor isn't functioning One of the first things a mechanic would look at is the state of charge of the battery and its terminals. If the battery is damaged or is depleted it must be charged or replaced.

Depending on the degree of the problem, the mechanic could test the solenoid on the starter using a multimeter. The solenoid is a huge magnetic switch that transmits the power of the thick battery cables to the starter. This switch basically connects the long battery cable to windings within the starter, which turn the electric motor as well as it pulls the rod, which turns an engaging fork, which in turn pushes the gear that pinions to automatically engage with the flywheel.

Another option is to disable the ignition switch with an extension wire. This is only a temporary fix that you should not try it unless sure how to do it. You'll need to be careful to connect your jumper wires to the battery terminals and make sure that the switch is in the "Start position".

Ignition Switch

The ignition switch is where you insert your key into the car. This will allow electrical flow to your starter and start up the engine, but it's not immune from wear and tear as other parts of your car. The switch can also get stuck inside its slot or be locked. You should be looking for issues frequently to be able to act before the car stops working.

If your key seems to struggle to turn or is stuck in the ignition, it may have been locked. This issue is common in vehicles due to a lack lubrication. Using a graphite or silicone-based grease on the pin that releases the key ignition replacement can help. Spray some lubricant into the ignition, then move the key. If you're stuck you can try using a piler or hacksaw blade.

A problem with the ignition can cause a variety of other issues, too. The anti-theft feature may not function or the starter motor might not turn on when you insert the key. It could also cause other functions to stop working or not work at all.

A failing ignition can also cause extra wear and tear on other parts. If you own keys with many items, or a bulky one, this could put strain on the ignition switch and increase wear on the internal components. Extreme temperature fluctuations may affect the materials and lubricants in the ignition switch.

Once you have a replacement ignition switch, it's important to test it prior to assembling the steering column and other parts. Make sure the replacement ignition switch works and that the engine starts smoothly. Double-check the compatibility of the new ignition switch with your vehicle model and model. It may be worthwhile to hire a dealership to install the ignition switch for you, if you aren't sure about your ability to do so. They can also test the replacement and install any other parts that require to be connected or replaced.
