A vehicle that does not click when it is turned over may have a bad ignition switch. If the lights on the dashboard turn on when the car is stalling, it is probably not the ignition switch.

An overheating ignition switch can be a big problem in cars, especially older models. The wires that connect the ignition switch to the controls of the car can become warped and can begin to put out too much energy. If the ignition switch is hot, these wires are probably overreacting and are arching in a way that does not let them connect. A car that has an overheating ignition switch should always be taken to a professional due to the risk of electrical fire in the dashboard.Learn more about Car Parts & Maintenance
