How much does it cost to fix a 2019 Ford F-350 Super Duty 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 initial diagnostic steps to troubleshoot the non-functional cruise control in a 2019 Ford F-350 Super Duty?

When troubleshooting the non-functional cruise control in a 2019 Ford F-350 Super Duty, it's essential to adopt a methodical diagnostic approach. Begin by checking the cruise control fuse located in the fuse box, as a blown fuse is a straightforward issue that can easily disrupt the system. Next, inspect the cruise control buttons on the steering wheel to ensure they are operational, as faulty buttons can prevent engagement. Following this, verify the functionality of the vehicle's speed sensors, since any malfunction here can significantly impact cruise control performance. Utilizing a diagnostic scanner to check for error codes can provide valuable insights into specific issues affecting the cruise control system. Additionally, examine the brake and clutch switches to confirm they are functioning correctly, as these components are crucial for activating cruise control. Finally, inspect the wiring and connections associated with the cruise control system for any signs of damage or corrosion, as poor connections can lead to failure. By systematically addressing these areas, you can effectively diagnose and potentially resolve the cruise control issue in your Ford F-350.

What are the common problems that could cause the cruise control to stop working in a 2019 Ford F-350 Super Duty?

When troubleshooting the cruise control system in a 2019 Ford F-350 Super Duty, it's essential to consider several common problems that could be affecting its functionality. One of the primary culprits 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, a malfunctioning speed sensor can disrupt the cruise control's ability to maintain a set speed, leading to erratic performance. It's also wise to check for a blown fuse, as this can completely disable the cruise control system. Other potential issues include throttle control problems, such as a faulty throttle position sensor, which can interfere with the system's operation. Furthermore, a defective cruise control module may need replacement if it is found to be the source of the problem. Lastly, electrical issues, including loose connections or damaged wiring, can significantly impact the cruise control's performance. By systematically addressing these common issues, you can effectively troubleshoot and potentially restore the cruise control functionality in your vehicle.

How urgent is it to address the non-functioning cruise control in a 2019 Ford F-350 Super Duty?

When it comes to a non-functioning cruise control in a 2019 Ford F-350 Super Duty, the urgency of addressing the issue cannot be overstated. While it may not seem like an immediate emergency, neglecting this problem can lead to serious safety risks and further complications. A malfunctioning cruise control system can cause erratic speed changes, which are particularly dangerous on highways where maintaining a steady speed is crucial for safe driving. Additionally, the underlying causes of cruise control failure, such as issues with the vehicle's electrical system or sensors, could escalate if left unaddressed, potentially leading to more significant and costly repairs. Therefore, it is advisable to prioritize the inspection and repair of the cruise control system to ensure not only the safety of the driver and passengers but also the overall functionality of the vehicle. Taking prompt action can prevent minor issues from developing into major problems, making it a wise decision for any DIY enthusiast or vehicle owner.
