How to Replace the Ignition Switch on a 1995 Nissan Altima


The ignition switch is part of a car’s starting system. When you turn the key to the start position, an electrical impulse runs to the solenoid, which activates the starter. When the starter engages the flywheel, it starts the engine. There are several reasons why you may want to change the ignition switch, including if you lose your keys or someone breaks the switch when trying to steal your car. Replacing the ignition switch on a 1995 Nissan Altima is not difficult but will take about two hours because you also have to remove the steering wheel.
