The most common reasons a 2014 Ram 3500 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 2014 Ram 3500 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 2014 Ram 3500?

To effectively diagnose the non-functioning cruise control on your 2014 Ram 3500, begin with the simplest solutions before progressing to more intricate checks. Start by inspecting the cruise control fuse, as a blown fuse can easily disrupt the system's functionality. Next, examine the cruise control buttons on the steering wheel to ensure they are operational, as malfunctioning buttons can prevent engagement. Following this, check the speed sensors, which are crucial for the cruise control to function correctly; faulty sensors can lead to significant issues. Utilizing a diagnostic scanner to search for error codes can provide valuable insights into any underlying problems. Additionally, verify that the brake and clutch switches are working properly, as these components play a vital role in activating the cruise control. Finally, inspect the wiring and connections for any signs of damage or looseness, as compromised wiring can interrupt the system's signals. By following this structured approach, you can efficiently diagnose and potentially resolve the cruise control issues in your Ram 3500.

What are the common problems that could cause the cruise control to stop working in a 2014 Ram 3500?

When dealing with a malfunctioning cruise control system in a 2014 Ram 3500, it's essential to understand the common problems that could be at play. One of the primary culprits is a faulty brake pedal switch, which is crucial for disengaging the cruise control when the brake is applied. If this switch is malfunctioning, it may prevent the system from engaging altogether. Additionally, issues with the speed sensor can disrupt the cruise control's ability to maintain speed, as it relies on accurate readings to function properly. Another potential issue is a blown fuse, which can cut power to the cruise control system, rendering it inoperative. Furthermore, a defective cruise control module may fail to communicate with the vehicle's systems, leading to a complete loss of functionality. Lastly, vacuum leaks within the cruise control system can also hinder its performance, as they disrupt the necessary pressure for operation. By identifying these common problems, DIYers can take the first steps toward diagnosing and potentially fixing their cruise control issues.

How urgent is it to address the malfunctioning cruise control in my 2014 Ram 3500?

When it comes to the malfunctioning cruise control in your 2014 Ram 3500, the urgency to address the issue cannot be overstated. A faulty cruise control system can lead to unexpected acceleration or deceleration, creating a significant safety hazard not only for you but also for other drivers on the road. Ignoring these symptoms may result in dangerous situations, including accidents or collisions, which could have been easily avoided with timely intervention. Furthermore, neglecting the problem can exacerbate the situation, potentially leading to more extensive damage to your vehicle's systems, resulting in costly repairs down the line. Therefore, it is crucial to prioritize the inspection and repair of your cruise control system by a qualified mechanic or dealership. Taking prompt action ensures not only your safety but also the longevity and reliability of your vehicle.
