The most common reasons a 2013 Ram 2500 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 2013 Ram 2500 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.

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 steps to diagnose the non-functioning cruise control on a 2013 Ram 2500?

To effectively diagnose the non-functioning cruise control on a 2013 Ram 2500, it's essential to adopt a systematic diagnostic approach that prioritizes simpler checks before delving into more complex issues. Begin by inspecting the fuse associated with the cruise control system, as a blown fuse is a straightforward and common culprit that can easily be overlooked. Next, examine the wiring for any signs of damage or loose connections, as these can disrupt the electrical flow necessary for the cruise control to operate. Following this, test the cruise control switch located on the steering wheel; a malfunctioning switch is often a frequent source of problems. Utilizing a diagnostic scanner to check for error codes can provide valuable insights into any underlying issues that may not be immediately visible. Additionally, ensure that the speed sensors are functioning correctly, as they play a crucial role in maintaining the desired speed. Lastly, verify that the brake lights are operational, since a faulty brake light switch can inadvertently disable the cruise control system for safety reasons. By methodically working through these steps, you can effectively identify and address the root cause of the cruise control malfunction.

What are the common problems that could cause the cruise control to stop working in a 2013 Ram 2500?

When troubleshooting cruise control issues in a 2013 Ram 2500, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty brake pedal switch, which is designed to disengage the cruise control when the brake is applied; if this switch malfunctions, it can prevent the system from engaging. Additionally, issues with the speed sensor can disrupt the vehicle's ability to maintain a constant speed, leading to cruise control failure. Another potential problem is a blown fuse within the cruise control system, which can easily be checked and replaced if necessary. Throttle control malfunctions can also hinder cruise control functionality, as they affect the system's ability to maintain speed. Furthermore, electrical problems, such as damaged or loose wiring connections, can interfere with the operation of the cruise control system. Lastly, a failure in the cruise control module itself may require repair or replacement to restore functionality. By systematically addressing these common issues, you can effectively troubleshoot and potentially resolve the cruise control problems in your Ram 2500.

How urgent is it to address the non-functioning cruise control in a 2013 Ram 2500?

Addressing a non-functioning cruise control in a 2013 Ram 2500 should be considered a priority for any DIY vehicle owner. While it may not seem like an immediate emergency, the implications of ignoring this issue can be significant. A malfunctioning cruise control system can indicate deeper problems within the vehicle's electrical system or sensors, which, if left unchecked, could lead to more severe mechanical failures. Moreover, the convenience of cruise control is particularly valuable during long drives, as it helps maintain a steady speed and reduces driver fatigue, ultimately enhancing safety and fuel efficiency. By taking the time to diagnose and repair the cruise control system promptly, you not only improve your driving experience but also prevent potential complications that could arise from neglecting the issue. Therefore, it is advisable to investigate the problem sooner rather than later, ensuring that your vehicle remains safe and efficient on the road.
