How to Fix Car Ignition Switch Problems

There are a myriad of reasons your car may run and start, but the ignition doesn't start the spark plugs. Some are easy and inexpensive to fix, whereas others require specialized equipment and the help of mechanics.

Lubricate the key socket first. You can use either graphite powder or silicon aerosol spray. Make sure that the ignition cylinder is free of no loose springs or obstructions.

Battery

If your car doesn't start it could be because the battery is dead. This is a common problem that can be solved with a battery charge or a jump. If this doesn't solve 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 as well as the ignition coil. If the ignition switch is damaged, it won't allow current to flow through, and the engine will not start.

The battery is the source of all electrical energy in your vehicle. The battery is a black, slender box with positive (+) and negative (-) terminals on the top. The terminals can be corroded, preventing the battery from providing electricity to the rest of the vehicle. Clean the battery's terminals by disconnection of the battery and using a wire brush to eliminate any corrosion. You can also clean the terminals using baking soda.

The battery in your car could be nearing the end of its lifespan and will require replacement. A new battery will provide the right voltage to your vehicle’s spark plugs. This is crucial to ensure that your engine is running properly.

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

It is possible to replace the starter motor too. If you hear a grinding sound as you turn your ignition key it means that the starter bearings are worn out. It can be an expensive repair so it is best to replace your starter motor immediately if you begin to notice signs of wear. The replacement of the starter motor is an easy task that requires replacing a few parts and bolts.

Alternator

The alternator charges your battery and powers the electrical components of your vehicle while the engine is running. Test the battery first if you suspect your alternator is failing. This will enable you to determine if your alternator draining the battery, or if your battery is old and needs replacement.

The alternator in your car also provides the power to the windshield wipers, dash lights, power windows, electric steering as well as heated seats and your radio even when the vehicle is idle. You can use a voltage meter to test your battery and alternator to determine the proper voltage levels. If your battery is less than 6 volts, it should be replaced or charged right away. A dead or weak battery will also prevent the starter motor from cranking the engine, and will require additional jumper cables to start your car.

Before you begin to dismantle the alternator, switch off the ignition and secure all doors. Remove the negative cable and secure it. Wear safety equipment. Consult a vehicle's specific repair manual to learn how to access the alternator and any other components you'll need to take off.

After you've removed your belt, Fix Car Ignition if the vehicle is equipped with one remove the warning light wire from the back of the alternator. This wire will connect directly to an alternator terminal marked WL or IN. Some vehicles have a separate relay that can perform this function. If your warning light doesn't blink, you may be able to identify a different issue.

The alternator is a vital part of your vehicle, and you must examine it regularly to look for signs of problems. You can carry out certain of these tests yourself, but it is best to bring your vehicle into Les Schwab so that they can look it over and offer you advice from a professional. Our technicians can test for corrosion on your battery posts, battery (+ and -) fuse, relays, and fuses as well as voltage output and cold starting amps and more.

Starter Motor

The starter motor is a crucial component in the ignition system. It is responsible for turning the engine to take in air, which is required to ignite the fuel. It is common for the starter motor to be the cause when your car won't turn over. There are many troubleshooting techniques that can be used to aid in diagnosing and fixing the issue.

When you turn the key in your vehicle's ignition the switch inside the starter engages with a pinion gear that fits into grooves on the flywheel. The pinion gear is then turned the flywheel, which begins the engine. When you release the key, the pinion gear retracts, and disengages from the flywheel, thereby preventing damage.

The starter motor may be affected by a range of things, including mechanical issues (such as teeth not lining up on the flywheel) or dead cells. A damaged starter motor could sound like a dead cell phone battery. It can make a clunk sound as it attempts to turn the engine over.

The state of charge and the battery's terminals will be examined by a mechanic in the event that the starter motor does not work. If the battery is damaged or is depleted, it will need to recharged 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 massive magnet switch, transmits an electric current from the battery cables to the starter. The switch connects the long cable from the battery to windings in the starter which will turn the motor. It also pushes a rod to actuate an engaging fork that pushes the pinion to automatically engage with flywheel.

A jumper wire can be used to bypass the ignition. This is a temporary option however it shouldn't be a recommendation unless you are able to do it correctly. You'll need to be careful about routing the jumper wire to battery terminals and make sure 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 the starter and then start the engine, however it's not immune to wear and tear like other car parts. The switch could also get stuck in its slot or locked. You should be looking for issues frequently to be able to act before your car doesn't start.

If your key is experiencing a struggle to turn or it is stuck in the ignition, it could have been locked. This is a problem that occurs in a variety of vehicles due to a lack lubrication. You can use a silicone or graphite-based grease to lubricate the release pin. Spray some lubricant onto the ignition, and then move the key. If you're stuck, try using a hacksaw or piler blade.

An issue with the ignition may lead to other problems. The anti-theft system may not function, or the starter motor might not crank when you put the key in. It can also cause auxiliary functions to cease functioning or cease to function altogether.

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

If you've purchased a replacement ignition switch, it's crucial to test it prior to assembling the steering column and the other components. Make sure the replacement ignition switch is working and that your engine is running smoothly. It is also important to confirm that the new ignition switch is compatible with your vehicle's model and model. If you're not sure of your ability to install a new ignition switch, it might be worth hiring a dealership service shop to complete the task for you. They can also test and connect other parts or even replace them.
