How to Fix Car Ignition Switch Problems

If your car starts and runs, but the ignition switch isn't able to switch over the spark plugs, there may be a myriad of reasons. Some are simple and cheap to fix, while others require specialized equipment and the help of an expert mechanic.

The first step is to lubricate the socket of the key. You can use either graphite powder or silicon aerosol spray. Also, make sure the ignition cylinder is free of any obstructions and loose springs.

Battery

It could be that your battery is dead when your car isn't starting. This is a frequent issue that can be resolved by a battery charge or the jump. If this does not solve the issue, it's possible that the ignition switch is bad. This component carries battery power to the other electrical components, including the starter motor and the ignition coil. If the ignition switch is faulty it will not allow current to flow through, and the engine will not start.

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

It is also possible that your car battery is nearing the end of its lifespan and needs to be replaced. A new battery will supply the right voltage to your vehicle’s spark plugs. This is necessary for a properly functioning engine.

The ignition coil converts the battery's low voltage into high voltage that causes the spark plugs in your car, and to start the engine. If the ignition coil is defective and is not in a position to ignite the plugs and your engine won't start. The ignition coil can be tested by checking the engine for a spark or turning the key to determine if it turns over.

It is also possible to replace your starter motor. If you hear a grinding sound when you turn the key in your ignition, it means that the bearings in the starter are beginning to wear out. It is a costly repair, so it is recommended to replace your starter motor immediately if you detect signs of wear. It's an easy task that requires replacing a few parts and bolts.

Alternator

The alternator is the one that charges your battery and also powers the electrical components of your car when the engine is running. Examine the battery first if you suspect that your alternator may be malfunctioning. This will allow you to determine if your alternator is causing your battery to run out or whether your battery is simply old and requires to be replaced.

When the vehicle is idle the alternator supplies power to the dash lights as well as the radio. It also powers the windshield wipers as well as the power windows, electric steering, heated seats, and the power windows. A voltmeter is a tool to test 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 dead or low-volt battery can also stop the starter motor from cranking the engine over and will require more jumper cables to get your car started.

Before you begin removing the alternator, make sure the ignition is turned off and all doors are locked. Also, disconnect the negative cable from the battery, and then put it away somewhere safe and put on your safety gear. Refer to a repair manual specific to your vehicle for instructions on how to remove the alternator, or any other component.

If your car has a warning light wire, you can disconnect it from the back of the generator following taking off the belt. This wire will connect directly to the alternator terminal marked WL or IN. Some vehicles have a separate relay to perform this function. If the warning light doesn't appear, you must be able to identify a different issue.

The alternator is a crucial component in your vehicle, and you must check it frequently to look for signs of problems. You can do certain of these tests by yourself, however it is best to bring your car into Les Schwab so that they can look it over and offer you advice from a professional. Our certified technicians will test your battery, battery posts (the terminals that are marked + and +) for corrosion relays, fuses, voltage output, cold cranking amps and more to determine what the problem is.





Starter Motor

The starter motor is an essential component in the ignition system. It turns the engine to allow air to be drawn in, which is needed to ignite the fuel. If your car isn't starting, it's typically due to a malfunction in the starter motor. There are a few ways to troubleshoot that can help you diagnose the problem and fix it.

When you turn on your vehicle's ignition, a switch in the starter engages with an pinion gear that is fitted into grooves on the flywheel. The pinion gear turns the flywheel, which in turn begins the engine. When you release the key the pinion gear retracts and is released from the flywheel to prevent damage.

The starter motor could be affected by a variety of things, including mechanical issues (such as teeth not meshing on the flywheel) or dead cells. A malfunctioning starter motor may sound like a dead cell phone battery. It can make a clicking sound as it tries but cannot turn the engine around.

If the starter motor doesn't work, one of the first things a mechanic will look at is the state of charge on the battery and its terminals. If the battery is depleted or has corrosion on its terminals, it'll need to be charged or replaced.

Depending on how serious the issue is, the mechanic could also test the solenoid with a multimeter. The solenoid is a huge magnetic switch that transmits an electric current from the thick battery cables to the starter. This switch basically connects the battery cable to the wires inside the starter that turn the electric motor, plus it pushes an actuator rod that turns on an engaging fork that is then pushed by the gear pinion to automatically engage with the flywheel.

Another option is to disable the ignition switch by using the jumper wire. This is only an interim solution and you shouldn't try it unless you're confident about how to do it. You'll need to carefully route the jumper wire to battery terminals and make sure the switch is set to the "Start" position.

Ignition Switch

The ignition switch is where you insert your keys into the car. This will allow electrical flow to your starter and start up the engine, but it's not immune to wear and tear as other parts of your car. The switch may also get stuck inside its slot or get locked. You should check for problems regularly to identify the problem before the car won't start.

It could be locked if your key is difficult to turn or gets stuck in the ignition. This is a typical issue for a variety of vehicles and occurs due to a lack lubrication. You can apply a graphite- or silicone-based oil to lubricate your release pin. Spray van ignition repair onto the ignition, and then move the key. If it's still stuck make use of a piler or a hacksaw blade to assist in moving it.

An ignition problem can lead to a number of other issues too. The anti-theft feature could not work or the starter motor might not turn on when you insert the key. It could also cause other functions to stop working or cease to function altogether.

A failing ignition can also cause additional wear and tear to other components. If you have keys that have multiple items or a heavy one, it can stress the ignition switch and accelerate wear on the internal components. Extreme temperature fluctuations may affect the lubricants and materials used in the ignition switch.

It is crucial to test the new ignition switch prior to reassembling other components and the steering column. Check that the replacement is working and that the engine is running without issue. Verify the compatibility of the new ignition switch with the vehicle's model and model. It may be worthwhile to have a dealership install the ignition switch for you if are not confident about your ability to install it. They will also test the replacement and install any other components that need to be connected or replaced.
