How Your Cherokee’s Ignition Switch Works

- Overheating is a common indicator that you could be having an ignition module problem. Ignition modules that are overheating will soon completely cease to function and in the meantime can cause cause electrical shorts, engine stuttering, lower gas mileage.
- Stalling on the Road. The most noticeable symptom of a bad ignition switch is stalling.
- Power the Accessories- This should be what you get when you turn the key to the first position. This allows you to use the power windows, radio, and any other accessory that is equipped in your Jeep Cherokee.
- Ignition- This position activates your ignition system and the fuel pump. At this point fuel is pressurized at the fuel rails, and the engine is ready to fire the plugs when it turns over.
- Starter- This position cranks the starter.

Common Bad Ignition Switch Symptoms: Jeep Cherokee
Here are some of the most common symptoms of an ignition switch failing in your Cherokee:
1. Stalling on the Road
The most noticeable symptom of a bad ignition switch is stalling. Your Cherokee stalls because the faulty switch turns off the fuel pump or power to the ignition. When this happens, the engine will not be able to run until it gets that signal back.
2. Starts then Dies
If your Jeep Cherokee is starting right up, but then immediately dies, that is a very good indication that the ignition switch is bad.
Here’s what happens. You aren’t getting power to the ignition or fuel pump while the key “rests” in the run position. But, you are getting it when the starter is engaged. So, you’ll hit the starter, everything has power. You release the key, and your Cherokee immediately dies.
3. Won’t Start at All
A bad ignition switch can cause your Cherokee not to start at all. And, it can keep your Cherokee from starting in a couple of different ways.
The first is when the starter cranks, but the bad ignition switch doesn’t turn on the fuel pump or ignition. The engine will just turn over with no spark. The second way is when the starter doesn’t turn at all. This can be frustrating, because a starter that doesn’t turn over at all is usually caused by a bad battery or a bad starter.
4. Lack of Power to Accessories
The ignition switch is responsible for sending power to the accessories. So, if you find yourself in a situation where your Cherokee runs, but nothing else in it works, it may be a bad ignition system causing your problems.
There are a few parts of the electrical system that work without the key at all for safety reasons, such as the headlights, brake lights, horn, and dome light.
Things such as the power windows (but not power locks), sunroof, radio, rear defrost, and climate control are all going to depend on the ignition switch for power. If several of them go bad at once, it’s time to test and see if the ignition switch is bad.
5. Battery Draining
