The most common reasons a 1996 Mitsubishi Eclipse cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 1996 Mitsubishi Eclipse cruise control isn't working?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

If the cruise control refuses to turn on at all, the actuator could be at fault. Likewise, if the cruise control stays on but does not maintain a consistent speed, the problem could be a bad actuator. In extreme cases, a malfunctioning actuator could cause the throttle to stick and prevent the vehicle from slowing down. These symptoms may point to a bad actuator. They may also point to other problems with the cruise control and related systems.

What are the initial diagnostic steps to troubleshoot the non-functional cruise control in a 1996 Mitsubishi Eclipse?

When troubleshooting the non-functional cruise control in a 1996 Mitsubishi Eclipse, it's essential to adopt a methodical diagnostic approach. Start by checking the cruise control fuse, as a blown or damaged fuse can often be the simplest fix. Next, inspect the cruise control switch located on the steering wheel to ensure it is operational; a malfunctioning switch can prevent the system from engaging. Pay attention to the cruise control buttons as well, ensuring they are not stuck or damaged, which could hinder functionality. After these initial checks, examine the cruise control module for any visible signs of damage or corrosion, as this component is crucial for system operation. Additionally, test the cruise control actuator to confirm it is receiving power and functioning correctly, as a faulty actuator can lead to system failure. Finally, verify the vehicle speed sensor, as it plays a vital role in cruise control operation; if it is not working properly, the system will not engage. By following these steps in order, you can effectively diagnose and address the issues with your cruise control system.

What are the common problems that could cause the cruise control to stop working in a 1996 Mitsubishi Eclipse?

When dealing with a malfunctioning cruise control system in a 1996 Mitsubishi Eclipse, it's crucial to understand the common problems that may be at play. One of the first areas to check is the cruise control switch, as a faulty switch can prevent the system from engaging. Additionally, a blown fuse can disrupt the electrical flow necessary for the cruise control to function, making it a simple yet often overlooked issue. Another potential culprit is vacuum leaks within the cruise control system, which can significantly impair its operation. The speed sensor also plays a vital role; if it is defective, it may cause the cruise control to disengage unexpectedly. Furthermore, issues with the brake light switch can inhibit the activation of the cruise control, as the system is designed to disengage when the brakes are applied. Lastly, a malfunctioning throttle cable can hinder the cruise control's ability to maintain a steady speed. By systematically checking these components, DIYers can effectively diagnose and resolve the cruise control issues in their Mitsubishi Eclipse.

How urgent is it to address the non-functioning cruise control in a 1996 Mitsubishi Eclipse?

When it comes to the non-functioning cruise control in a 1996 Mitsubishi Eclipse, understanding the urgency of the situation is crucial for any DIY enthusiast. While the immediate safety of the vehicle may not be compromised, neglecting this issue can lead to more significant problems over time. A malfunctioning cruise control system can be indicative of underlying electrical issues or sensor failures that, if left unaddressed, could escalate into costly repairs or affect the vehicle's overall performance. Moreover, the convenience of cruise control, which aids in maintaining a steady speed and reducing driver fatigue, is lost, potentially making long drives more taxing. Therefore, while it may not be an emergency, it is advisable to inspect and repair the cruise control system promptly. This proactive approach not only ensures a more enjoyable driving experience but also helps maintain the integrity of the vehicle, preventing further complications down the road.
