The park brake warning light on your 2014 Chrysler 200 is designed to illuminate when the parking brake is engaged. However, if you’re facing a situation where the light stays on, flickers intermittently, or comes on even when the parking brake is released, it indicates a potential issue with the park brake warning switch wiring. This article serves as a guide to help you troubleshoot and potentially resolve these issues.
Understanding the Park Brake Warning System
The park brake warning system is a simple yet crucial safety feature in your vehicle. It comprises several components working in tandem:
- Park Brake Lever: Engaging this lever activates the parking brake.
- Park Brake Switch: This switch, usually located near the parking brake lever assembly, is responsible for sending a signal to the instrument cluster to illuminate the warning light.
- Wiring Harness: Connects the park brake switch to the vehicle’s electrical system and the instrument cluster.
- Instrument Cluster: Displays the park brake warning light.

Common Causes of Park Brake Warning Switch Wiring Issues
Several factors can contribute to problems with the park brake warning switch wiring in your 2014 Chrysler 200:
- Loose or Damaged Wiring: Over time, vibrations or general wear and tear can cause the wiring harness connecting the park brake switch to become loose or damaged. This disrupts the signal flow, leading to a malfunctioning warning light.
- Faulty Park Brake Switch: The switch itself can wear out or become damaged, preventing it from sending the correct signal.
- Corrosion: Exposure to moisture can lead to corrosion on the switch terminals or within the wiring harness, hindering electrical conductivity and causing intermittent or permanent warning light issues.
- Stuck Parking Brake Mechanism: While not directly related to the switch wiring, a stuck parking brake cable or mechanism can keep the switch constantly engaged, causing the warning light to stay on.
Troubleshooting Steps
Before assuming the worst-case scenario, it’s best to perform some basic troubleshooting to identify the root cause:
-
Visual Inspection: Begin by visually inspecting the park brake switch and the wiring harness connected to it. Look for any signs of physical damage, loose connections, or corrosion.
-
Check the Parking Brake Lever: Ensure the parking brake lever is fully released. Sometimes, the lever might not return to its resting position entirely, causing the switch to remain engaged.
-
Test the Switch Continuity: Using a multimeter, you can test the continuity of the park brake switch. If the switch fails to show continuity when the parking brake is engaged and disengaged, it indicates a faulty switch requiring replacement.
“Testing the switch with a multimeter is a straightforward process, even for beginners. However, if you are unsure about working with electrical components, it is always best to seek assistance from a qualified mechanic.” – Mark Stevenson, ASE Certified Master Technician

Inspect the Wiring Harness: Carefully examine the wiring harness for any signs of damage, such as cuts, abrasions, or exposed wires. Pay close attention to areas where the harness might rub against other components. If you identify any damage, the affected section of the wiring harness needs to be repaired or replaced.

Check for Corrosion: Examine the park brake switch terminals and the wiring harness connectors for any signs of corrosion. If you find any, cleaning the affected areas with an electrical contact cleaner can often resolve the issue. However, heavily corroded components might need replacement.
Seeking Professional Help
While the troubleshooting steps mentioned above can help you identify and potentially fix simple problems, more complex issues might require the expertise of a qualified automotive electrician or mechanic.
