Q:

What are the signs of a bad ignition switch?

A:

Signs of a bad ignition switch could include dashboard lights that come off and on, problems with the vehicle starting and a switch that is hot to the touch. A bad ignition switch can mimic other problems that are seen in a car, such as a faulty motor starter.

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. Lights that do not turn on when the ignition switch is turned to the second position is one of the surest signs that an ignition switch is bad. A bad starter will not affect the way that the dashboard warning lights come on.

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.
