Why Is My Jeep Liberty Making A Clicking Sound?

The most common reason a Jeep Liberty won’t start is usually related to an issue with the battery or charging system.

Sometimes a battery will have just enough juice to power the radio or lights but not enough to crank the engine.

Other times there will be nothing but some clicking sounds when you turn the key. That is generally a sign of a dead battery or an issue with the starter or ignition.

Common reasons a battery may be weak or dead:

  • The lights or radio were left on while the vehicle was not running
  • The battery is old
  • The alternator is not charging the battery

If you find that you have a weak or dead battery the simple solution is to have someone give you a jump start if possible.

Generally, once the vehicle has been jump-started the battery will recharge as it is driving and you won’t experience any more issues unless something is going on with the alternator or wiring system.

It is always a good idea to keep a set of jumper cables and some basic tools in your Jeep Liberty in the event it won’t start.

Some batteries have a cover that needs to be removed before you can access the terminals to jump-start the engine. That is why it is helpful to keep tools in your vehicle.

Corrosion And Bad Connections

Another common issue that occurs is dirt or corrosion build-up on the battery terminals. Generally, a simple cleaning will solve this issue and you will be running the roads in no time.

To clean the terminals on your battery you can use a wire brush or battery terminal cleaning tool. Another old trick that people use is to pour Coca-Cola on the corroded battery terminals.

The Coke bubbles up and helps to remove the crusty buildup that is preventing your battery from getting a good connection.

Additionally, it is not uncommon for a ground wire to need replacing. If the vehicle is not grounded properly it cannot make the proper connections it needs to start the engine.

It can be helpful to own a multimeter that can help you to determine which connections or wires are bad. A multimeter can save a lot of time because you are not playing a guessing game of which wire is bad.

Sickly Starter Or Wires

A bad starter motor or components will definitely cause your Jeep Liberty to not start. If the starter is not properly grounded it will also cause the vehicle not to start. Be sure to check that the wires to the starter are properly connected.

If you want to try to diagnose a bad starter at home you will need someone to sit in the Jeep and try to start the vehicle as you gently tap on the starter motor with a hammer. Oftentimes as you are tapping and someone is working the ignition the vehicle will start.

If tapping on the starter gets your engine going then you know it is time to have the starter replaced so you don’t end up stranded in a parking lot or at the gas pump.

Lack Of Fuel

If you are having issues with your fuel system such as a weak fuel filter or dirty fuel injectors it can prevent your Jeep Liberty from starting. The engine needs to get the proper fuel-to-air ratio to start and run properly.

Preventative Maintenance Keeps The Tow Truck Away
