The most common reasons a 2006 Jeep Commander 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 2006 Jeep Commander 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.

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.

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.

What are the initial diagnostic steps to troubleshoot the non-functioning cruise control in a 2006 Jeep Commander?

When troubleshooting the non-functioning cruise control in a 2006 Jeep Commander, it's essential to adopt a systematic diagnostic approach. Begin by checking the fuse associated with the cruise control system, as a blown fuse can easily disrupt its operation. Next, inspect the cruise control switch for any visible damage or wear, since a malfunctioning switch can prevent the system from engaging. It's also crucial to examine the brake lights, as they are interconnected with the cruise control; if the brake lights are not working, this could hinder the cruise control's functionality. Utilizing a diagnostic scanner to check for error codes can provide insights into specific issues affecting the system. Finally, assess the vehicle speed sensor, as a faulty sensor can impede the cruise control from maintaining the desired speed. By following these steps, you can effectively identify and address the underlying issues with your Jeep's cruise control system.

What are the common problems that could cause the cruise control to stop working in a 2006 Jeep Commander?

When dealing with a malfunctioning cruise control system in a 2006 Jeep Commander, it's essential to consider several common issues that could be at play. One of the primary culprits is a faulty brake light switch, which can prevent the cruise control from engaging since the system is designed to disengage when the brake pedal is pressed. Additionally, problems with the speed sensor can disrupt the cruise control's functionality, as it relies on accurate speed readings to operate correctly. Another potential issue is vacuum leaks within the system, which can affect the necessary vacuum pressure for proper operation. A defective cruise control module may also be responsible for the malfunction, as it plays a crucial role in the system's overall performance. Lastly, electrical problems, including blown fuses, wiring issues, or a faulty cruise control switch, can lead to the system not working as intended. By identifying and addressing these common problems, DIYers can effectively troubleshoot and restore the cruise control functionality in their Jeep Commander.

How urgent is it to address the malfunctioning cruise control in a 2006 Jeep Commander?

Addressing a malfunctioning cruise control in a 2006 Jeep Commander is crucial for both safety and vehicle performance. When cruise control fails, it can lead to unpredictable acceleration or deceleration, significantly increasing the risk of accidents on the road. This unpredictability not only compromises your safety but also that of other drivers. Additionally, a malfunctioning system can make long drives uncomfortable, as you may find yourself constantly adjusting your speed manually. Ignoring these symptoms can also lead to higher fuel consumption, as the vehicle struggles to maintain a consistent speed. Furthermore, neglecting the issue may result in more severe damage to the vehicle's electrical components, leading to costly repairs down the line. Therefore, it is advisable to address any cruise control malfunctions promptly to ensure a safe and enjoyable driving experience.
