The Fix Car Ignition Awards: The Best, Worst And Weirdest Things We've Ever Seen How to Fix Car Ignition Switch Problems    If your car is running and starts, but the ignition switch doesn't switch over the spark plugs, there may be a number of reasons. Some are easy and cheap to fix, others require specialized tools and assistance from a mechanic.    Lubricate the socket before you use it. You can use either graphite powder, or a silicon aerosol 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 due to the battery being dead. This is a frequent issue that can be resolved by charging the battery or making the jump. If this doesn't fix the problem, it is likely that your ignition switch is not working properly. This component is responsible for transferring power from the battery to other electrical components, such as the starter motor and ignition coil. If the ignition switch is defective it won't permit current to flow through it and the engine will not start.    The battery is the source of all the electrical energy in your vehicle. It's a dark box with positive (+) and negative (-) terminals on top. The terminals can be corroded, preventing the battery from providing power to the rest of the vehicle. By disconnecting the battery you can employ a wire bristle get rid of any corrosion. You can also apply baking soda as a solution to help clean the terminals.    It is also possible that your car battery is at the end of its lifespan and requires replacement. A new battery will supply the correct voltage to your vehicle’s spark plugs. This is crucial for a properly functioning engine.    The ignition coil converts low voltage from your battery into high voltage, which causes it to ignite the spark plugs of your car, and to start the engine. If your ignition coil is not working properly it won't be able to spark the plugs. Your engine won't start. You can test the ignition coil by looking for a spark inside the engine or turning the key and seeing if the engine turns over.    You may need to replace the starter motor too. If you hear a grinding sound as you turn your ignition key it is a sign that the starter bearings are wearing out. This can be a costly repair so it's best to replace the starter motor early on if you notice any signs of wear and tear. It's an easy process that requires the replacement of some bolts and parts.    Alternator    The alternator charges your battery and also powers the electrical components of your car when the engine is running. Test the battery first if you suspect that your alternator may be malfunctioning. This will allow you to determine if the alternator is causing your battery to drain or the battery is just old and requires to be replaced.    Your car's alternator also supplies the power to the dashboard lights, windshield wipers, power windows, electric steering, heated seats and your radio when the vehicle is idling. You can use a voltmeter to check your battery and the alternator to determine the proper voltage levels. If your battery is less than 6 volts, it must be replaced or charged right away. A low or dead battery can also stop the starter motor from turning the engine over and will require more jumper cables to start your car.    Before you begin dismantling the alternator, switch off the ignition and lock all doors. Disconnect the negative cable and secure it. Wear safety equipment. Check out a specific vehicle repair manual for guidance on how to access the alternator, as well as any other parts you need 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. This wire will connect directly to the alternator terminal marked WL or IN. Some vehicles, however, have a separate relay for this function. If the warning light doesn't blink, you may think about a different cause.      You should check regularly your alternator for indications of a malfunction. While you can do some of the checks yourself, it's best to bring your vehicle into Les Schwab for a complimentary inspection and expert advice. Our technicians can check for corrosion on your battery posts, battery (+ and +) fuse, relays, and fuses as well as voltage output, cold starting amps, and more.    Starter Motor    The starter motor is a crucial component of the ignition system. It is responsible for turning over the engine to suck in air, which is necessary to ignite the fuel. If your car won't start, it's typically due to a malfunction in the starter motor. Fortunately, there are several ways to troubleshoot that can aid in diagnosing and fixing the issue.    When you turn on your vehicle's ignition key, a switch within the starter engages a pinion-gear that fits into grooves of the flywheel. The pinion gear turns the flywheel, which initiates the engine. The gear retracts when you release the key to avoid damage.    The starter motor may be affected by a variety of things, including mechanical issues (such as teeth not meshing on the flywheel) or dead cells. A faulty starter motor can sound like a dead cell phone battery. It can make a clicking sound as it tries to turn the engine around.    If the starter motor isn't functioning, one of the first things a mechanic should look at is the state of charge on the battery and its terminals. If the battery is not fully charged or has corrosion on its terminals, it'll require charging or replaced.    Depending on the degree of the problem The mechanic can also examine the solenoid of the starter with a multimeter. The solenoid is a huge magnet switch, delivers an energy surge from the battery cables to the starter. This switch basically connects the long battery cable to the wires inside the starter that actually activate the electric motor and also pushes the rod, which turns an engaging fork that in turn pushes the gear pinion to automatically engage with the flywheel.    A jumper wire can be used to bypass the ignition. This is a temporary solution however it shouldn't be a recommendation unless you are able to do it right. You'll need to be careful to route your jumper wires to the battery terminals, and make sure that the switch is in the "Start position".    Ignition Switch    The ignition switch is the place where you insert your car key. It is used to start the engine and to send an electrical current to the starter. However, it is not immune to wear like other parts of the car. The switch can also become stuck in its slot or locked. It is essential to check it regularly for any issues so that you can act before the car stops working.    It could have been locked if the key is difficult to turn or gets stuck in the ignition. This is a common issue for many vehicles and happens due to a lack lubrication. You can make use of a graphite or silicone-based lubricant to lubricate the release pin. Spray a little into the ignition and try moving the key. If it's stuck you can try using a hacksaw or piler blade.    van ignition repair with the ignition could cause a host of other issues too. The anti-theft function may stop working or the starter motor might not turn on when you insert the key. It could also cause other functions to stop working or not work at all.    A malfunctioning ignition switch could also cause a lot of extra wear and tear on other components. For example, if you carry a bulky keychain, or several items on your keychain, it could strain the ignition switch when you insert it in and can accelerate the wear and tear on its internal components. Extreme temperature fluctuations can affect the lubricants and materials in the ignition switch.    It's important to test the replacement ignition switch prior to reassembling other components and the steering column. Be sure that 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 make and model. If you're unsure of your ability to install an ignition switch that is new, it might be worth hiring a service shop at a dealership to complete the task for you. They can also test the new switch and install any other parts that need to be connected or replaced.
