How to Fix Car Ignition Switch Problems

If your car starts and runs, but the ignition switch doesn't turn on the spark plugs, there may be a myriad of causes. Some are simple and cheap to fix, while others require specialized equipment and help of mechanics.

First, lubricate the socket that holds the key. You can apply graphite powder or silicon spray. Make sure that the ignition cylinder is clean and has no loose springs or obstructions.

Battery

If your car doesn't start, it could be due to the battery being dead. This is a common problem that can be solved by getting a jump or charging of the battery. If this doesn't fix the issue, it's possible that the ignition switch is not working properly. This component carries battery power to other electrical components, including the starter motor and the ignition coil. If the ignition switch is defective, it won't allow current to flow through and the engine will not start.

The battery is the source of all the electrical energy that is used in your car. It's a black, insulated box with positive (+) and negative (-) terminals that are on the top. The terminals could become corroded and prevent the battery from providing 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 a baking soda solution to help clean the terminals.

It's possible that your vehicle's battery is at the end of its life and requires replacement. A new battery will provide the right voltage to your vehicle's spark plugs, which is required to ensure a functioning engine.

The ignition coil converts the battery's low voltage into high voltage to spark the spark plugs of your car, and to start the engine. If your ignition coil is defective, it will not be able to spark the plugs. The engine will not start. The ignition coil can be checked by examining the engine for sparks or turning the key to check if it turns over.

You may have to replace the starter motor, too. If you hear a grinding sound when you turn on your ignition, it is a sign that the bearings inside the starter are starting to wear out. It is a costly repair, so it is recommended to replace your starter motor immediately if you detect signs of wear. Changing the starter motor is an easy task that involves replacing a few parts and bolts.

Alternator

The alternator is an instrument that charges your battery when your engine is running. It also powers your car's electrical components. Check the battery first if you suspect your alternator is failing. This will enable you to determine if your alternator is draining the battery or if the battery is old and requires replacement.

While the vehicle is idle the alternator supplies power to the dash lights as well as the radio. It also powers the windshield wipers, the power windows, the electric steering, the heated seats and the power windows. You can use a voltage meter to check your battery and the alternator for the proper voltage levels. If your battery is less than 6 volts, then it needs to be charged or replaced immediately. A low or dead battery will also prevent the starter motor from turning the engine over and will require more jumper cables to start your car ignition switch replacement.

Before you begin dismantling the Alternator, turn off the ignition and secure all doors. Disconnect the negative cable and store it safely. Wear safety equipment. Refer to a repair manual specific to your vehicle for directions on how to remove the alternator or any other parts.

If your vehicle is equipped with a warning light wire, you can remove it from the back of the generator after removing the belt. This will usually connect directly to the alternator's terminal that's labeled either WL or IND. Certain vehicles have a separate relay that can perform this function. If your warning light does not come on, you should be able to identify a different issue.

The alternator is a vital component in your vehicle, and it is important to check it frequently for signs of problems. You can do certain of these tests by yourself, however it is best to bring your car ignition switch replacement to Les Schwab so that they can look it over and give you expert advice. Our highly trained technicians can test your battery, battery posts (the terminals marked + and +) for corrosion relays, fuses, voltage output and cold cranking amps, and more to determine what the problem is.

Starter Motor

The starter motor is a crucial component of the ignition system. It rotates the engine to allow air to be sucked in, which is needed to ignite the fuel. It is common for the starter motor to be at fault when your car doesn't turn. There are a variety of methods of troubleshooting that can aid in diagnosing and fixing the problem.

When you turn on the ignition of your vehicle the switch inside the starter turns on an pinion gear that is fitted into grooves on the flywheel. The pinion gear is then turned the flywheel, which then begins the engine. The gear retracts when you remove the key, thereby preventing damage.

The starter motor may be affected by a range of factors, including mechanical issues (such as teeth that don't mesh on the flywheel) or dead cells. A faulty starter motor can sound like a dead phone battery. It can make a clicking sound as it tries but cannot turn the engine.

The condition of the battery and the terminals of the battery will be checked by a mechanic when the starter motor fails to work. If the battery is low or has corrosion on its terminals, it'll need to be charged or replaced.

Depending on the extent of the problem, the mechanic could test the starter solenoid with a multimeter. The solenoid is a massive magnet switch, sends an electric current from the thick batteries cables to the starter. The switch connects the long battery cable to the wires inside the starter, which turn the electric motor, plus it pushes the rod, which turns an engaging fork which will then push the pinion gear to automatically engage with the flywheel.

Another option is to disable the ignition switch using a jumper wire. This is a temporary option but it shouldn't be recommended unless you are able to do it right. You'll need to take care to connect your jumper wires the battery terminals, and then make sure that the switch is in the "Start position".

Ignition Switch

The ignition switch is the place where you insert your key into the car. It is used to start the engine and send electrical current to the starter. However, it is not immune to wear and tear as other components of the car. The switch may also get stuck in its slot or get locked. It is important to check it frequently for any issues so that you can act before the car doesn't start.

If your key seems to struggle to turn, or becomes stuck in the ignition, it might be locked. This is a common problem for a variety of vehicles and occurs because of a lack of lubrication. Using a silicone or graphite-based oil on the release pin can help. Spray some lubricant into the ignition, then move the key. If it's stuck, try using a piler or hacksaw blade.

A problem with the ignition can also lead to other problems. The anti-theft system may not function or the starter motor might not start when you plug in the key. It could also cause other functions to cease functioning or cease to function altogether.

A damaged ignition may cause extra wear and tear to other components. If you have keys that have multiple items, or a large one, this could put strain on the ignition switch and increase wear on the internal components. Extreme temperature fluctuations may affect the lubricants and materials in the ignition switch.

If you've got a new ignition switch, it's important to test it before reassembling the steering column and other components. Check that the replacement works and that the engine is running without issue. Also, make sure the new ignition switch is compatible with the vehicle's make and model. If you're not confident in your ability to install an ignition switch that is new you might consider employing a dealership service shop to install it for you. They will also test the replacement and install any other parts that need to be connected or replaced.
