How to Fix Car Ignition Switch Problems
There are a variety of reasons your car may run and start but the ignition won't start the spark plugs. Some are simple and inexpensive to fix, others require specialized tools and help from a mechanic.
The first step is to 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 obstructions or loose springs.
Battery
If your car won't start it could be because the battery is dead. This is a common issue that can be resolved by charging the battery or making an electrical jump. If this doesn't solve the issue your ignition switch could be defective. This component supplies battery power to other electrical components, such as the starter motor and the ignition coil. If the ignition switch is damaged it will not allow current to pass through and the engine will not begin.
The battery is responsible for all the electrical energy in your vehicle. It's a black, insulated box with positive (+) and negative (-) terminals that are on top. The terminals can become corroded and prevent the battery from providing power to the rest the vehicle. By disconnecting the battery, you can employ a wire bristle get rid of any corrosion. You can also clean the terminals with baking soda as a solution.
It is also possible that your car battery is at the end of its lifespan and requires replacement. A new battery will supply the proper 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 in your car and then start the engine. If the ignition coil is faulty, it won't be capable of sparking the plugs, and your engine will not start. The ignition coil can be inspected by checking the engine for sparks or turning the key to determine whether it is turning.
You may have to replace the starter motor too. If you hear a grinding sound as you turn on your ignition, this means that the starter bearings are wearing out. It is a costly repair so it is best to replace your starter motor immediately if you notice signs of wear. The replacement of the starter motor is an easy process that requires replacing a few parts and bolts.
Alternator
The alternator is an appliance that charges your battery while your engine is running. It also is the power source for your car's electrical components. If you suspect that there is a problem with your alternator you should first test the battery. This will enable you to determine if your alternator is draining the battery or if the battery is old and requires replacement.
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, the heated seats and the power windows. You can use a voltmeter examine your battery and alternator for the proper voltage levels. If your battery is less than 6 volts, it should be replaced or charged as soon as possible. car ignition switch repair that are dead or not charged will also prevent the starter from turning over the engine and will require additional jumper cables to begin your vehicle.
Before you begin dismantling the alternator, ensure the ignition is off and all doors are locked. Also, disconnect the negative cable from the battery, and then put it away in a safe location and put on your safety equipment. Consult a vehicle's specific repair manual for guidance on how to access the alternator, as well as any other components you'll need to take off.
If your car has a warning light wire, you can remove it from the side of the generator after taking off the belt. It will typically connect directly to the alternator's terminal that is marked WL or IND. Some vehicles have a separate relay to perform this function. If your warning light doesn't appear, it is likely that you have an issue with your vehicle.
The alternator is a crucial part of your vehicle, and you must examine it regularly for signs of trouble. You can do certain of these tests yourself, but it's best to bring your vehicle into Les Schwab so that they can examine it and provide you with expert advice. Our highly trained technicians can examine 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 in the ignition system. It turns the engine to allow air to be sucked into it and ignite the fuel. If your car won't start, it's usually due to a problem with the starter motor. There are a few troubleshooting methods that can help you identify the problem and fix it.
When you turn on your car's ignition key, a switch within the starter turns on a pinion-gear that fits into grooves in the flywheel. The pinion gear turns the flywheel that initiates the engine. When you release the key, the pinion gear retracts, and disconnects from the flywheel to avoid damage.
There are many things that could go wrong in the starter motor, for example, an electrical issue in the internal windings, mechanical issues (such as teeth no longer meshing on the pinion gear or flywheel) or a dead battery. A faulty starter motor can sound like a dead phone battery. It will make a clicking sound when it tries to turn the engine around.
If the starter motor doesn't work, one of the first things a mechanic should check is the state of charge of the battery and its terminals. If the battery has corrosion or is not functioning properly it must be recharged or replaced.
Depending on how severe the issue is, the mechanic may test the solenoid by using a multimeter. The solenoid is a massive magnet switch, sends an energy surge from the battery cables to the starter. This switch connects the bulky cable from the battery to starter's windings that will turn the motor. It also triggers an axis rod to trigger an engaging fork which pushes the pinion to automatically engage the flywheel.
A jumper wire can be used to disable the ignition. This is only a temporary fix and you shouldn't try it unless you're sure how to do it. You will need to carefully connect your jumper wires the battery terminals and make sure that the switch is in the "Start position".
Ignition Switch
The ignition switch is where you insert your key into the car. It is used to start the engine and send electric current to the starter. However it isn't immune to wear and tear like other parts of the car. The switch can also get stuck inside its slot or get locked. You should check for problems frequently to be able to act before the car stops working.
If your key seems to struggle to turn, or is stuck in the ignition, it may be locked. This is a common issue for many vehicles and happens because of a lack of lubrication. Using a graphite or silicone-based oil on the release pin could help. Spray some lubricant onto the ignition, then move the key. If it's still stuck, use a piler or hacksaw blade to help move it.
An issue with the ignition can also cause other issues. The anti-theft system may stop working, or the starter motor may not start when you plug in the key. This can also cause the auxiliary functions to stop working or cease to function.
A failing ignition switch can also cause a lot of extra wear and tear on other parts. 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 put it in, and could increase the wear on its internal components. Extreme temperature fluctuations can impact the materials and lubricants in the ignition switch.
It's important to test the new ignition switch before reassembling other components and the steering column. Be sure that the replacement ignition switch is working and that your engine starts smoothly. Also, make sure the new ignition switch is compatible with the vehicle's make and model. If you're unsure of your ability to install the new ignition switch, it might be worth hiring a dealership service shop to install it for you. They can also test and connect other components or replace them.
