The most common reasons a 1997 Saturn SC2 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 1997 Saturn SC2 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 throttle position sensor fails, the engine's computer tends to overcompensate with fuel, leading black exhaust coming from the tailpipe. There is a strong possibility of engine misfires, and the check engine light will come on.

Throttle position sensors can also develop "dead spots," or certain places along the throttle curve where it doesn't get a reading. When this happens, the above symptoms can occur but then stop when you further press or let off the gas pedal.

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.

The cruise control switch can cause complete failure of the cruise control feature, but in a lucky scenario only partial functionality will be lost. This means that the cruise control may come on, but that it will not increase in speed automatically, or the cancel button does not work leading the driver to cancel cruise control with the foot brake. In some vehicles, the cruise control light may illuminate, or a warning message may be displayed due to lack of functionality.

A faulty cruise control module will simply result in deactivation of cruise control settings. This is because a detected error in the cruise control system could lead to hazardous driving conditions, so the module will be disabled, and the cruise control system warning light will be displayed. This will be a different message depending on make and model, and a warning light or message may be displayed on the driver instrument cluster.

What are the initial diagnostic steps to troubleshoot the non-functioning cruise control in a 1997 Saturn SC2?

When troubleshooting the non-functioning cruise control in a 1997 Saturn SC2, it's essential to adopt a systematic diagnostic approach. Begin by checking the fuse associated with the cruise control system, as a blown fuse is a straightforward issue that can easily be resolved. Next, inspect the cruise control switch to ensure it is operational; a malfunctioning switch can often be the culprit behind the system's failure. Following this, examine the brake pedal switch, which is crucial since the cruise control disengages when the brake is applied. If these components check out, turn your attention to the vacuum lines, as any leaks can disrupt the cruise control's functionality. Additionally, verify the speed sensor's performance, as it provides necessary data for the system to operate correctly. Finally, if the problem persists, using a diagnostic scanner to check for error codes can help identify more complex issues. By following this structured approach, you can effectively diagnose and potentially resolve the cruise control problem in your Saturn SC2.

What are the common problems that could cause the cruise control to stop working in a 1997 Saturn SC2?

When dealing with cruise control issues in a 1997 Saturn SC2, it's important to consider several common problems that could be at play. One of the first things to check is the fuse associated with the cruise control system; a blown fuse can easily disrupt its functionality. Additionally, the brake pedal switch is crucial, as it is designed to deactivate the cruise control when the brake is engaged; if this switch is faulty, it may prevent the system from operating. Another potential culprit is the cruise control module itself, which can fail and lead to a complete loss of control. Furthermore, vacuum leaks within the cruise control system can significantly affect its performance, as these leaks can disrupt the necessary pressure for operation. Lastly, a defective speed sensor can hinder the cruise control's ability to maintain a consistent speed, resulting in failure. By systematically checking these components, DIYers can effectively diagnose and address the cruise control issues in their Saturn SC2.

How urgent is it to repair the non-functioning cruise control in a 1997 Saturn SC2?

When evaluating the urgency of repairing the non-functioning cruise control in your 1997 Saturn SC2, it's essential to weigh the implications of neglecting this issue. While cruise control is not critical for the vehicle's basic operation, its malfunction can lead to safety concerns, especially if it distracts you while driving. If you find yourself frequently on long highway trips, the absence of this feature may contribute to driver fatigue, making it a more pressing matter. Additionally, if you plan to sell your vehicle soon, having all features in working order, including cruise control, can enhance its appeal and potentially increase its resale value. Therefore, while the repair may not be urgent in the traditional sense, addressing it sooner rather than later can improve your driving experience and maintain the vehicle's overall value. Consulting with a mechanic can provide further insights into the specific issues at hand and help you make an informed decision based on your driving habits and priorities.
