How much does it cost to fix a 2017 Ram ProMaster City 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 take when the cruise control isn't working on a 2017 Ram ProMaster City?

When faced with a malfunctioning cruise control system in your 2017 Ram ProMaster City, it's essential to adopt a systematic diagnostic approach. Begin by checking the fuse associated with the cruise control; a blown fuse is a common culprit that can easily be overlooked. Next, inspect the cruise control switch to ensure it is operational, as a faulty switch can prevent the system from engaging. Following this, verify the speed sensors, as they play a crucial role in maintaining the set speed; any malfunction here can disrupt the entire system. Additionally, examine the wiring connections for any signs of damage or looseness, as these can lead to connectivity issues. Finally, utilizing a diagnostic scanner to check for error codes can provide deeper insights into any underlying problems. By methodically working through these steps, you can effectively identify and address the reasons behind your cruise control's failure, making your DIY troubleshooting both efficient and effective.

What are the common problems that could cause the cruise control to stop working in a 2017 Ram ProMaster City?

When the cruise control in your 2017 Ram ProMaster City ceases to function, it can be frustrating, but understanding the common problems can help you diagnose the issue effectively. One of the primary culprits is a faulty cruise control switch, which may fail to engage the system properly. Additionally, a blown fuse in the vehicle's fuse box can disrupt the electrical flow necessary for the cruise control to operate. Another potential issue lies with the speed sensor; if this component is malfunctioning, it can prevent the cruise control from maintaining the desired speed. Furthermore, a defective brake light switch can interfere with the system, as it is designed to disengage cruise control when the brakes are applied. Lastly, problems with the throttle control system can also hinder the cruise control's ability to function correctly. By identifying these common issues, you can take the first steps toward troubleshooting and potentially resolving the cruise control problem in your vehicle.

How urgent is it to address the malfunctioning cruise control in my 2017 Ram ProMaster City?

Addressing the malfunctioning cruise control in your 2017 Ram ProMaster City is of utmost importance due to the safety risks it poses. A malfunction can lead to unexpected acceleration or deceleration, which can create hazardous driving conditions for you and others on the road. Additionally, a faulty cruise control system can significantly detract from your driving experience, especially during long trips, where the convenience of cruise control is often relied upon for comfort. Ignoring these symptoms not only compromises your safety but can also lead to further wear and tear on your vehicle's components, resulting in more extensive and costly repairs down the line. Therefore, it is crucial to prioritize the diagnosis and repair of your cruise control system to ensure a safe and enjoyable driving experience.
