Your Jeep Cherokee won’t start, and all you hear is a clicking sound? This frustrating issue can stem from various problems, from a simple dead battery to a more complex starter or electrical system malfunction. This comprehensive guide will walk you through the common causes, troubleshooting steps, and potential solutions to get your Jeep back on the road.
Understanding the Clicking Sound
The clicking sound you hear is usually the starter solenoid engaging but not having enough power to crank the engine. This can be due to a weak battery, corroded terminals, a faulty starter, or issues with the ignition system. Identifying the root cause is crucial for effective repair.
Dead or Weak Battery
The most common culprit behind a clicking sound is a dead or weak battery. Over time, batteries lose their ability to hold a charge, especially in extreme temperatures. Try jump-starting your Cherokee. If it starts, this confirms a battery issue. You might need a new battery or simply need to charge the existing one.

Corroded Battery Terminals
Even if your battery has enough charge, corroded terminals can prevent the current from reaching the starter. Check your battery terminals for any white, powdery buildup. If present, clean them with a wire brush and a mixture of baking soda and water.
Faulty Starter Motor
If the battery and terminals are fine, the starter motor itself might be the issue. A failing starter might only click instead of cranking the engine. You can test the starter by tapping it lightly with a hammer or wrench while someone tries to start the car. If it starts, the starter is likely faulty and needs replacement.

Ignition System Problems
Problems with the ignition system, such as a faulty ignition switch or a bad relay, can also prevent the starter from receiving power. Check the ignition switch for any loose connections or damage. You might also need to test the relays with a multimeter to ensure they are functioning correctly.
Other Potential Causes
Less common causes include a bad neutral safety switch (automatic transmission) or a wiring issue. A neutral safety switch prevents the car from starting unless it’s in park or neutral. A wiring issue anywhere in the starting circuit can also cause clicking sounds.
Troubleshooting Jeep Cherokee Starting Problems
Here’s a step-by-step guide to troubleshoot your clicking Jeep Cherokee:
- Check the Battery: Jump-start the car. If it starts, the battery is the problem.
- Clean the Terminals: Remove and clean any corrosion from the battery terminals.
- Test the Starter: Tap the starter lightly while someone tries to start the car.
- Inspect the Ignition System: Check the ignition switch and relays for any issues.
- Check the Neutral Safety Switch (Automatic Transmission): Try starting the car in both park and neutral.
- Check Wiring: Inspect the wiring for any damage or loose connections.
