How do you know when the ignition switch gone bad?

Answer 1

Ignition switch going bad can be,hard starting,some things work while others don't and all your fuses look good.For example,not long ago a 1998 s-10 blazer would start,but the electric windows wouldn't work and the interior fan wouldn't blow.The mechanic replaced ignition switch to fix the problem,gas mileage went way up also.Also if you have to hold the ignition key in a certain position to make things work,its probably gone bad.Also any smoke or burnt smell around the steering column is a sure sign of problems. you.

Answer 2

We'll divide this question into two sections. Ignition key lock is defective if: 1. Key is hard to insert or remove. ( try a little WD40 ) 2. Key doesn't spring back from start. 3. Key doesn't find the detents (stops) for: lock, acc., run. Then the Ignition Key Lock is defective, and usual problem. Ignition Switch: This is much harder to detect. You will have to get the wiring diagrams for your ignition switch, remove the switch, and check each terminal for defects. The usual problem is a broken wire in the system. If you have a specific problem, like not starting, then reask your question with the sympton.

Answer 3

It will not engage and send current to the starter. You will not hear a click or anything else if the ignition switch is bad. With your headlights on when you turn the ignition if the lights dim is it not the ignition switch but more than likely a bad starter. If the lights do not dim it is more than likely the ignition switch.

Answer 4

If you turn the key and only hear a click the starter is more than likely bad. If it does not even click either the battery is dead, you have a loose connection, or the ignition switch is defective.

Answer 5

If the switch fails, however, you won't be able to start your vehicle

Answer 6

...then the car won't start. It's not like were talking quantum physics here.
