The most common reasons a 1995 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 1995 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 1995 Mitsubishi Eclipse?

When troubleshooting the non-functional cruise control in a 1995 Mitsubishi Eclipse, it's crucial to adopt a systematic diagnostic approach. Start by checking the cruise control fuse; a blown fuse is often the simplest issue to resolve and can immediately restore functionality. Next, inspect the cruise control switch located on the steering wheel, as a malfunctioning switch may require replacement. Following this, examine the condition of the cruise control vacuum hoses for any signs of leaks or damage, as these can significantly impact the system's performance. Additionally, ensure that the throttle cable is properly adjusted, as misalignment can interfere with cruise control operation. Finally, test the brake light switch, since a faulty switch can disable the cruise control as a safety precaution. By methodically addressing these areas, you can effectively diagnose and potentially fix the cruise control issue in your Mitsubishi Eclipse, saving time and money on professional repairs.

What are the common problems that could cause the cruise control to stop working in a 1995 Mitsubishi Eclipse?

When troubleshooting the cruise control system in a 1995 Mitsubishi Eclipse, it's essential to consider several common problems that could be at play. A blown fuse is often the first culprit to check, as it can completely disable the system. If the fuse is intact, the next step is to inspect the cruise control switch, which may be faulty and prevent proper engagement. Additionally, vacuum leaks can disrupt the system's operation, so examining the vacuum lines for any signs of wear or damage is crucial. The speed sensor also plays a vital role; if it's malfunctioning, the cruise control may struggle to maintain a constant speed. Furthermore, issues with the brake light switch can interfere with the system's ability to engage or disengage, while a malfunctioning throttle cable can hinder speed maintenance. By systematically checking these components, DIYers can effectively diagnose and address the issues affecting their cruise control system.

How urgent is it to repair the non-functioning cruise control in a 1995 Mitsubishi Eclipse?

When evaluating the urgency of repairing the non-functioning cruise control in a 1995 Mitsubishi Eclipse, it's essential to weigh the implications of neglecting this feature. While cruise control is primarily a convenience, its absence can lead to increased driver fatigue during long journeys, potentially compromising safety. If the lack of this feature distracts you or makes driving less comfortable, it may warrant prompt attention. Additionally, if you plan to sell the vehicle, having all systems operational, including cruise control, can enhance its resale value, making it more appealing to potential buyers. Before making a decision, consider having a mechanic conduct a diagnostic check to identify the underlying issue. This assessment can provide clarity on whether the malfunction poses any risks or could lead to further complications down the line. Ultimately, while the repair may not be urgent from a safety standpoint, addressing it sooner rather than later can improve your driving experience and maintain the vehicle's value.
