Experiencing issues with your Jeep Wrangler's cruise control can be frustrating, especially if you're used to long drives and highway cruising. This guide will help you identify common problems and solutions for when your cruise control won't turn on.

Common Reasons for Cruise Control Malfunction

Cruise control issues in Jeep Wranglers can arise from various factors. Here are the most frequent causes:
  • Faulty Cruise Control Switch: The switch on the steering wheel may become unresponsive or defective over time.

  • Clock Spring Failure: This component allows electrical connections through the steering wheel. If it fails, cruise control may not function.

  • Blown Fuse: A blown fuse can prevent the cruise control system from operating. Check fuse M37 in your fuse box.

  • Brake Light Switch Issues: If the brake light switch is malfunctioning, it can disable the cruise control system as a safety measure.

  • Electrical Connections: Loose or damaged wiring can disrupt the cruise control function.

Troubleshooting Steps

If your Jeep Wrangler's cruise control won't turn on, follow these troubleshooting steps:

1. Check the Fuse: Locate the fuse box and inspect fuse M37. If it's blown, replace it with a new 10 amp fuse.

2. Inspect the Cruise Control Switch: Test the switch by pressing it multiple times or giving the steering wheel a gentle tap. Sometimes, a simple reset can resolve minor issues.

3. Examine the Clock Spring: If you suspect this part is faulty, you may need to remove the steering wheel to inspect or replace it. Ensure all electrical connections are secure.

4. Test the Brake Light Switch: Ensure that your brake lights are functioning properly. If they remain stuck on, this could indicate a problem with the brake light switch that needs to be addressed.

5. Reset the System: Disconnecting and reconnecting the battery may reset the cruise control system and resolve temporary glitches.

6. Check Electrical Connections: Inspect wiring for any signs of wear or damage that could affect functionality.

When to Seek Professional Help

If you've gone through these troubleshooting steps and your cruise control still won't activate, it may be time to consult a professional mechanic. They can run diagnostics to identify deeper electrical issues or replace components like the cruise control switch or clock spring if necessary.
