How to Fix Car Ignition Switch Problems

If your car starts and runs, but the ignition switch isn't able to turn on the spark plugs, it could be a variety of causes. Some are simple and cheap to fix, while 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. Also, ensure that the ignition cylinder is free of obstructions and springs that are loose.

Battery

It could be that your battery is dead if your car isn't starting. This is a common problem which can be resolved with an extra jump or charging the battery. If this does not fix the issue, your ignition switch may be bad. This component supplies battery power to other electrical components, including the starter motor and the ignition coil. If the ignition switch is damaged it won't permit current to flow through it and the engine won't begin.

The battery is the source of all electrical energy in your vehicle. It's a black box with positive (+) and negative (-) terminals that are on top. The terminals may become corrosion-prone, which can stop the battery from supplying power to the rest the vehicle. By disconnecting the battery, you can employ a wire bristle remove any corrosion. You can also apply baking soda to clean the terminals.

Your car's battery could be nearing the end of its lifespan and requires replacement. A new battery will supply the right voltage to your vehicle’s spark plugs. This is essential for a properly functioning engine.

The ignition coil converts the battery's low voltage into high voltage to spark the spark plugs in your car, and to start the engine. If the ignition coil is faulty and is not capable of sparking the plugs and your engine will not start. You can test the ignition coil by looking for a spark inside the engine or turning the key to see whether the engine is turning.

It is also possible to replace the starter motor. If you hear a grating 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 best to replace your starter motor as soon as you detect signs of wear. Changing the starter motor is an easy task that requires the replacement of a few parts and bolts.

Alternator

The alternator is an appliance that recharges your battery while your engine is running. It also is the power source for your car's electrical components. If you suspect a issue with your alternator, you should test the battery first. This will help you determine if your alternator is draining the battery or if the battery is old and needs replacement.

When the vehicle is idle, the alternator provides power to the dash light and radio. It also powers the windshield wipers as well as the power windows, the electric steering, heated seats and the power windows. You can use a voltmeter to check your battery and the alternator for the proper voltage levels. If your battery's voltage is lower than 6 volts, it should be replaced or charged as soon as possible. A dead or weak battery will also prevent the starter motor from cranking the engine over and will require additional jumper cables to start your car.

Before you begin to dismantle the Alternator, turn off the ignition and lock all doors. Also, disconnect the negative cable from the battery, tuck it away in a safe place and put on safety gear. Check out a specific vehicle repair manual for guidance on how to gain access to the alternator as well as any other components you require to remove.

Once you've removed the belt, if your vehicle is equipped with one take off the warning light wire from the back of the alternator. The wire will be connected directly to the alternator terminal identified WL or IN. Certain vehicles, however, have a separate relay for this function. If your warning light does not blink, it's likely that you have a different issue.

The alternator is a vital component of your vehicle, and it is important to check it frequently for signs of trouble. While you can perform some of the tests by yourself, you should bring your vehicle into Les Schwab for a free inspection and expert advice. Our technicians will test for corrosion on your battery posts, battery (+ and +) fuse, relays, and fuses and voltage output, cold starting amps, and more.

Starter Motor

The starter motor is an essential component of the ignition system. It is responsible for turning over the engine so that it can draw into air, which is essential to ignite the fuel. It is typical that the starter motor will be the cause when your car isn't turning over. There are a few ways to troubleshoot that can help you identify the problem and fix it.

When you turn the key ignition replacement 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 that starts the engine. The gear retracts when you release the key to prevent damage.

The starter motor may be affected by a number of things, such as mechanical problems (such as teeth not meshing on the flywheel) or dead cells. A malfunctioning starter motor may sound like a dead phone battery. It can make a clicking sound when it tries to turn the engine around.

If the starter motor isn't functioning, one of the first things a mechanic should check is the state of charge on the battery and its terminals. If the battery is depleted or has corrosion on its terminals, it will require charging or replaced.

Depending on how serious the issue is, a mechanic may also test the solenoid with a multimeter. The solenoid is a large magnetic switch that sends a rush of power from the thick battery cables to the starter. The switch connects the battery cable to windings within the starter that activate the electric motor, plus it pushes a rod that actuates an engaging fork, which in turn pushes the gear pinion to automatically engage with the flywheel.

A jumper wire can be used to disable the ignition. This is only a temporary solution however it shouldn't be a recommendation unless you are able to do it right. You will need to carefully connect your jumper wires the battery terminals, and make sure that the switch is in the "Start position".

ignition lock repair near me Switch

The ignition switch is where you insert your keys into the car. This will enable electrical flow to your starter and to start the engine, but it isn't immune to wear and tear as other car components. The switch could also get stuck in its slot or even locked. It's important to regularly check it for problems so that you can take action before the car doesn't start.

If your key seems to struggle to turn or is stuck in the ignition, it could have been locked. This problem occurs in many vehicles because of a lack lubrication. You can apply a graphite- or silicone-based grease to lubricate the release pin. Spray some lubricant into the ignition, then move the key. If it's stuck then try using a hacksaw or piler blade.

An issue with the ignition could lead to other problems. The anti-theft feature may not function or the starter motor may not be able to turn on when you insert the key. This can cause other functions to stop functioning or cease to function.

A failing ignition can also cause extra wear and tear to other components. For instance, if you carry a bulky keychain or a variety of items on your keychain it could put strain on the ignition switch when you plug it in, and could increase the wear on its internal components. Extreme temperature fluctuations may affect the materials and lubricants in the ignition switch.

If you've got a new ignition switch, you need to test it before reassembling the steering column and the other components. Make sure the replacement works and that your engine starts without any issues. Double-check the compatibility of the new ignition switch with your vehicle model and make. It could be worth it to have a dealership 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 components that require to be connected or replaced.
