The most common reasons a Saturn Aura 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 Saturn Aura 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.

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.

Troubleshooting Cruise Control Issues in a Saturn Aura

When troubleshooting cruise control issues in your Saturn Aura, it's crucial to adopt a systematic diagnostic approach. Begin by inspecting the cruise control switch for any visible signs of damage or wear, as this is often the simplest fix. Next, check the brake lights; if they are illuminating incorrectly, this could indicate a malfunction that affects the cruise control system. Following this, examine the throttle and sensor components, as these are integral to the cruise control's functionality. Ensure that there is proper communication between the cruise control switch, the body control module (BCM), and the engine control module (ECM). If these initial checks do not resolve the issue, it may be necessary to delve deeper into the system's wiring and connections or consult a certified mechanic for a more thorough diagnosis. By methodically addressing these areas, you can effectively identify and resolve cruise control problems in your Saturn Aura.

What Could Cause the Cruise Control to Malfunction in a Saturn Aura?

When diagnosing cruise control malfunctions in a Saturn Aura, it's essential to consider several common problems that may arise. One of the primary culprits is the throttle and sensor issues, which can disrupt the communication between the vehicle's systems and prevent the cruise control from functioning correctly. Additionally, a failure in the Cruise Control Module can lead to a complete loss of steering wheel functions, further complicating the issue. It's also important to inspect the Relay Switch Box and the harness cables that connect the steering wheel to the Cruise Control Module, as any faults here can interrupt the power supply necessary for the system to operate. The Body Control Module (BCM) plays a crucial role as it monitors the cruise control signals, so any malfunction in this component can hinder the system's responsiveness. Lastly, checking the inflatable restraint steering wheel module coil is vital, as it ensures that the cruise control switches are activated correctly in relation to the steering wheel's position. By understanding these common problems, DIY enthusiasts can effectively troubleshoot and address cruise control issues in their Saturn Aura.

Why is the Cruise Control Not Working in a Saturn Aura?

When your Saturn Aura's cruise control stops functioning, it's crucial to address the issue without delay. Ignoring symptoms like the "service esc / service traction" warning lights can not only compromise your driving experience but also pose significant safety risks. A malfunctioning cruise control system may indicate underlying problems such as a failed control module, faulty sensors, or issues with the throttle position sensor, which can lead to erratic engine behavior and even black exhaust emissions. Additionally, a blown fuse or a defective brake pedal switch can prevent the cruise control from engaging, potentially leading to dangerous situations on the road. By diagnosing and resolving these issues early, you can ensure your vehicle operates safely and efficiently, preventing further damage and costly repairs down the line. Always consult your vehicle's manual or a professional if you're unsure about the necessary steps to take.
