Jeep Compass Won’t Start: 7 Causes and Fixes

Causes Of Start System Jeep Compass Not Working

Are you experiencing trouble with your jeep compass start system? Frustrated that it won’t turn on? Countless factors may cause the start system in your jeep compass to malfunction.

Dead Battery

A dead battery is the most common cause of a failed start system. If your battery voltage is too low, it won’t have enough energy to initiate the starter motor.

  • Dimming headlights
  • Car horn sounds weak
  • Electrical components not working

Faulty Starter Motor

A starter motor is responsible for transferring energy from the battery to the engine’s crankshaft to get it started. A faulty starter motor is a common issue that will result in your jeep compass not starting.

  • Grinding sound when starting the vehicle
  • You might hear a clicking sound, but the engine doesn’t start.

Malfunctioning Alternator

A malfunctioning alternator prevents your battery from getting charged, which will cause your vehicle’s start system to malfunction.

  • Flickering headlights or other electrical components
  • Electrical components not working properly.

Failed Ignition Switch

An ignition switch is an electronic component that starts the engine when you turn the key. When an ignition switch fails, the engine won’t start, and your jeep compass won’t start.

  • Turning the key does nothing
  • Difficulty starting the vehicle

Looking out for these signs can help you identify which of these issues is causing your jeep compass start system to not work. These issues can be easily fixed by having your jeep compass diagnosed by a qualified mechanic.

Troubleshooting The Start System Jeep Compass

Has your start system jeep compass stopped working? It can be frustrating when you turn the key, and nothing happens. This section will go through some simple steps you can take to troubleshoot your jeep compass start system. Follow these step-by-step guidelines, using a multimeter to test the battery and starter, inspecting the alternator and ignition switch, and replacing faulty components.

Step-By-Step Guide On How To Diagnose The Start System Problems

Diagnosing start system problems can be challenging. Here’s a step-by-step guide to help you understand how to check effectively.

  • Turn the ignition key: when you turn the key, pay attention to whether you hear any sound or see any lights on the dashboard.
  • Check the battery connections: open the hood of your jeep compass and check the battery connections. Make sure they’re secure and clean.
  • Test the battery voltage: use a multimeter to test the voltage of your jeep compass battery. A fully charged battery should read between 12. 6 and 12. 8 volts. If the reading is less than 12. 2 volts, it may need charging or replacing.
  • Check the starter motor: locate the starter motor and check that the wires are tightly attached and secure. Use the multimeter to check the voltage of the starter motor. If the voltage reading is zero, the starter motor may need replacing.

Using A Multimeter To Test The Battery And Starter

Without a doubt, a multimeter is a valuable tool when troubleshooting start system problems.

  • Testing the battery voltage: set up your multimeter to measure volts and connect the positive and negative probes to the corresponding terminals on the battery. If the volts reading is low, charge the battery.
  • Testing the starter motor: set your multimeter to measure voltage and connect the probes to the motor’s terminals. If the voltage reading is zero, replace the motor.

Inspecting The Alternator And Ignition Switch

When troubleshooting start system problems, it’s essential to inspect the alternator and ignition switch.

  • Alternator inspection: use a multimeter to test the alternator by connecting the probes to the battery terminals and starting the engine. If the volts reading increases to around 14 volts, then the alternator is working. If not, replace it.
  • Ignition switch inspection: turn the key and check if the engine starts. If it doesn’t, inspect the ignition switch contacts for corrosion. If it’s corroded, replace the switch.

Replacing The Faulty Components

After troubleshooting and inspecting the parts, if you find a faulty component, it’s time to replace it. If the battery is dead or not charging, replace it. If the starter motor or alternator is defective, replace them with a new one.

If the ignition switch contacts are corroded, replace the switch.

Troubleshooting a start system jeep compass not working needs a step-by-step approach. Diagnose the problem, use a multimeter to check the battery and starter, inspect the alternator and ignition switch, and replace any faulty component.
