Turn the key to different positions and check the resistance readings. The readings should match the specifications in the manufacturer’s manual.
2. Can a faulty ignition switch cause my car not to start?
Yes, a faulty ignition switch can cause your car not to start. If the switch is not sending power to the starter motor, the engine will not start. It is important to diagnose and fix any issues with the ignition switch as soon as possible.
3. How do I replace my ignition switch?
To replace your ignition switch, you will need to disconnect the battery, remove the steering wheel, and disassemble the steering column. The ignition switch is usually located near the base of the column. You can remove the old switch and install the new one, following the instructions in the manufacturer’s manual.
4. What is the difference between a five-position and a four-position ignition switch?
The main difference between a five-position ignition switch and a four-position ignition switch is that the five-position switch has an additional position for accessories. The four-position switch only has positions for off, accessory, run, and start.
