How much does it cost to fix a 2014 Ram ProMaster 1500 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.

What are the steps to diagnose the cruise control issue in a 2014 Ram ProMaster 1500?

To effectively diagnose a cruise control issue in your 2014 Ram ProMaster 1500, begin with the simplest solutions before progressing to more intricate checks. Start by inspecting the cruise control fuse; a blown fuse can often be the root of the problem and is an easy fix. Next, examine the wiring connections associated with the cruise control system for any signs of damage or corrosion, as these can disrupt functionality. Utilizing a diagnostic scanner to check for error codes can provide insights into specific malfunctions, guiding your next steps. After that, test the cruise control switch to ensure it is operational, as a faulty switch can prevent the system from engaging. Additionally, inspect the speed sensors, as they play a crucial role in the system's performance; if they are malfunctioning, the cruise control may not activate. Finally, verify the brake pedal switch, which is essential for the cruise control to function correctly; a defective switch can disable the system entirely. If these steps do not resolve the issue, seeking assistance from a professional mechanic may be necessary to ensure a thorough diagnosis and repair. By following this structured approach, you can efficiently identify and address the cruise control problem in your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2014 Ram ProMaster 1500?

When troubleshooting cruise control issues in a 2014 Ram ProMaster 1500, it's essential to consider several common problems 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, issues with the speed sensor can disrupt the cruise control's functionality, as it relies on accurate speed readings to maintain the desired speed. A blown fuse related to the cruise control system is another potential issue; checking and replacing any blown fuses can often resolve the problem. If these components are functioning correctly, the cruise control module itself may be faulty and require repair or replacement. Furthermore, a malfunction in the throttle control system, such as a defective throttle position sensor, can hinder the cruise control's ability to maintain speed. Lastly, electrical problems, including wiring issues or loose connections, can also lead to cruise control failure. By systematically addressing these common issues, DIY enthusiasts can effectively troubleshoot and restore the cruise control functionality in their vehicle.

How urgent is it to address the non-functioning cruise control in a 2014 Ram ProMaster 1500?

Addressing a non-functioning cruise control in a 2014 Ram ProMaster 1500 is more urgent than it may initially seem. While it might not appear to be 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 cruise control feature is designed to enhance driving comfort and fuel efficiency, particularly on long trips. Without it, drivers may experience increased fatigue and reduced control over their vehicle, especially on highways where maintaining a consistent speed is crucial for safety. Therefore, it is advisable for DIY enthusiasts to inspect and repair the cruise control system promptly. This proactive approach not only ensures safer driving conditions but also helps prevent potential damage that could result in higher repair costs down the line. Taking the time to address this issue can lead to a more reliable and enjoyable driving experience.
