How much does it cost to fix a 2012 Ram C/V 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.

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 2012 Ram C/V?

When faced with a non-functioning cruise control in a 2012 Ram C/V, it's crucial to adopt a systematic diagnostic approach. Start by checking the cruise control fuse in the fuse box; a blown fuse can often be the simplest fix. Next, inspect the cruise control switch on the steering wheel for any signs of damage or wear, as a malfunctioning switch can prevent the system from engaging. The brake pedal switch is another critical component to examine, as it should disengage the cruise control when pressed; ensure it is functioning correctly and not stuck. Additionally, the vehicle speed sensor plays a vital role in maintaining speed, so verify that it is operational and providing accurate readings. Finally, using a diagnostic scanner to check for error codes can reveal underlying issues that may not be immediately apparent. By following these steps, you can effectively troubleshoot and potentially resolve the cruise control malfunction in your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2012 Ram C/V?

When dealing with a non-functional cruise control in a 2012 Ram C/V, 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 deactivate when the brake pedal is pressed. Additionally, a defective speed sensor may disrupt the system's ability to maintain a constant speed, leading to its failure. It's also wise to check for a blown fuse in the vehicle's electrical system, as this can halt the cruise control's operation entirely. Furthermore, vacuum leaks in the engine can significantly impact the cruise control system, as it relies on vacuum pressure to function correctly. Lastly, a malfunctioning cruise control module could be the reason behind the system's inability to engage or maintain speed. By systematically addressing these potential issues, DIYers can effectively troubleshoot and potentially resolve the cruise control problems in their vehicle.

How urgent is it to address the non-functioning cruise control in a 2012 Ram C/V?

Addressing a non-functioning cruise control in a 2012 Ram C/V is important, even if it may not seem like an immediate emergency. While the absence of this feature may not directly compromise safety, it can lead to driver fatigue during long trips and inconvenience on highways where maintaining a steady speed is beneficial. Ignoring the malfunction could result in increased fuel consumption due to inconsistent speed control, negatively impacting the vehicle's efficiency. Moreover, delaying repairs may allow underlying issues to escalate, potentially causing further damage to the vehicle's electrical system or related components. Therefore, it is advisable to prioritize the repair of the cruise control system to ensure optimal driving comfort, safety, and overall vehicle performance.
