How to Fix Car Ignition Switch Problems

There are a variety of reasons your car may be running and starting but the ignition fails to start the spark plugs. Some are simple and inexpensive to fix, whereas others require specialized equipment and assistance of an expert mechanic.

Lubricate the socket before you use it. You can make use of graphite powder or silicon spray. Make sure that the ignition cylinder has no loose springs or obstructions.

Battery

If your car won't start it could be due to the battery being dead. This is a frequent issue that can be resolved by either charging your battery or an electrical jump. If this does not fix the issue, your ignition switch may be bad. 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 won't allow current to be passed through, and the engine won't begin.

The battery is responsible for all the electrical energy you use in your vehicle. The battery is a black, slender box that has positive (+) and negatively (-) terminals on the top. The terminals may become corroded and prevent the battery from supplying power to the rest the vehicle. By disconnecting the battery, you can make use of a wire bristle to remove any corrosion. You can also use baking soda as a solution to help clean the terminals.

It is possible that your vehicle's battery is nearing the end of its life and needs to be replaced. A new battery will supply the proper voltage to your vehicle’s spark plugs. This is essential to ensure that your engine is running properly.

The ignition coil is responsible for converting low voltage from the battery to high voltage that can ignite the spark plugs in your car to start the engine. If your ignition coil is not working properly and not functioning properly, it will not be able to ignite the plugs. The engine will not start. The ignition coil can be inspected by examining the engine for a spark or turning the key to determine whether it spins.

It is also possible to replace your starter motor. If you hear a grinding sound when you turn the key in your ignition, it is a sign that the bearings in the starter are beginning to wear out. It can be an expensive repair, so it is recommended to replace your starter motor immediately if you begin to notice signs of wear. The starter motor can be changed by replacing the bolts and parts.

Alternator

The alternator is an appliance that charges your battery while your engine is running. It also provides power to your car's electrical parts. Test the battery first if you suspect your alternator may be malfunctioning. This will help you determine whether your alternator is causing the battery to drain or your battery is old and requires to be replaced.

The alternator in your car also provides power for your dashboard lights, windshield wipers, electric steering, power windows, heated seats and your radio even when the car is running. A voltmeter can be used to check the voltage of your alternator and battery. If your battery's voltage is lower than 6 volts, then it needs to be replaced or charged immediately. A low or dead batteries will also stop the starter from turning the engine on, and will require additional jumper cables in order to start your vehicle.

Before you begin removing the Alternator, turn off the ignition and lock all doors. It is also important to disconnect the negative cable from the battery, and then put it away in a safe place and put on the safety equipment. Refer to a repair ignition lock cylinder manual specific to your vehicle for directions on how to remove the alternator or any other component.

After you've removed the belt, if the vehicle is equipped with one take off the warning light wire from the side of the alternator. This wire will usually connect directly to a terminal on the alternator that is marked either WL or IND. Certain vehicles have an additional relay that performs this function. If your warning light doesn't come on, it is likely that there is an issue with your vehicle.

The alternator is a vital component of your vehicle, and you should check it frequently for signs of trouble. While you can do some of the tests on your own, it's recommended to bring your vehicle to Les Schwab for a free inspection and expert advice. Our certified technicians will examine your battery posts, battery (the terminals marked + and -) for corrosion, fuses, relays as well as voltage output and cold cranking amps, and more to determine what the issue is.

Starter Motor

The starter motor is an essential component in the ignition system. It rotates the engine so that air can be drawn in, which is needed to ignite the fuel. When your car won't start it's typically due to a problem with the starter motor. There are a variety of troubleshooting techniques that can be used to assist you in identifying and fixing the issue.

When you turn the key in the ignition of your vehicle, a switch in the starter is activated by the pinion gear, which fits into grooves on the flywheel. The pinion gear then turns the flywheel, which starts the engine. The gear retracts once you remove the key, thereby preventing damage.

There are a variety of things that can be wrong with the starter motor including an electrical failure in the internal windings, mechanical issues (such as teeth no longer meshing on the pinion gear or flywheel) or a dead battery. Often, a defective starter motor will just sound like a dead battery; it will make a clicking sound when it attempts to turn over the engine, but it won't.

If the starter motor isn't working, one of the first things a mechanic would check is the state of charge of the battery and its terminals. If the battery is damaged or is low it needs to be recharged or replaced.

Depending on the extent of the problem The mechanic can also examine the solenoid of the starter with a multimeter. The solenoid, which is a large magnet switch, transmits an energy surge from the battery cables to the starter. The switch connects the battery cable to windings within the starter, which turn the electric motor, plus it pushes a rod that actuates an engaging fork, which is then pushed by the gear that pinions to automatically engage with the flywheel.

A jumper wire can be used to bypass the ignition. This is a temporary option, and it isn't recommended unless you know how to do it correctly. 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 car keys. This will allow electrical flow to your starter and then start the engine, but it's not immune from wear and tear like other car components. The switch may also become stuck in its slot or locked. It is essential to check it frequently for problems so that you can take action before the car stops working.

It is possible that your key was locked if your key is difficult to turn or becomes stuck in the ignition. This issue occurs in a variety of vehicles due to a lack of oil lubrication. Using some graphite or silicone-based lubricant on the release pin can aid. Spray a small amount into the ignition and try moving the key. If it's stuck, make use of a piler or a hacksaw blade to assist in moving it.

An issue with the ignition may lead to other problems. The anti-theft function may not work or the starter motor could not start when you insert the key. This can also cause the other functions to stop functioning or lose power.

A failing ignition can also cause extra wear and tear on other components. For example, if you have a heavy keychain or a variety of items on your keychain, it could put strain on the ignition key replacement switch when you plug it in and can accelerate the wear on its internal components. Extreme temperature fluctuations can affect the materials and lubricants in the ignition switch.

Once you have a replacement ignition switch, it's important to test it prior reassembling the steering column and other components. Check that the replacement works and that the engine is running without issue. Make sure that the new ignition switch with the vehicle's model and make. If you're unsure of your ability to install the new ignition switch, it might be worth hiring a service shop at a dealership to do it for you. They can also test and connect other parts or even replace them.
