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.
When troubleshooting the non-functional cruise control in a 2017 GMC Savana 2500, it's important to follow a methodical diagnostic approach that prioritizes simpler issues before tackling more complex ones. Begin by checking the cruise control fuse, as a blown fuse can easily interrupt the system's operation. Next, assess the cruise control switch to ensure it is functioning properly; a faulty switch can prevent the system from engaging. The brake pedal switch is another critical component to inspect, as it directly affects cruise control functionality—if this switch is malfunctioning, it can disable the entire system. Additionally, examine the vehicle speed sensor, which provides essential speed data to the cruise control; any issues with this sensor can lead to operational failures. Utilizing a diagnostic scanner to check for stored trouble codes can also provide valuable insights into specific problems affecting the cruise control system. Finally, inspect the wiring and connections related to the cruise control for any signs of damage or corrosion, as compromised wiring can significantly hinder performance. By systematically addressing these areas, you can effectively diagnose and resolve the issues impacting your cruise control system.
When the cruise control in your 2017 GMC Savana 2500 stops functioning, it can be frustrating, but understanding the common problems can help you diagnose the issue effectively. 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 at all. Another potential issue is related to the speed sensor; if this component is not accurately relaying speed information, the cruise control may struggle to maintain a constant speed. Additionally, a blown fuse in the vehicle's electrical system can disrupt the cruise control operation, so checking the fuses is a good first step. Problems with the throttle actuator can also arise, as this part is responsible for controlling engine speed and can hinder the cruise control's ability to function properly. Lastly, a malfunctioning cruise control module itself can be the root of the problem, and diagnosing this may require more in-depth troubleshooting. By systematically checking these components, you can identify and resolve the issues affecting your cruise control system, allowing you to get back on the road with confidence.
Addressing a non-functioning cruise control in a 2017 GMC Savana 2500 should be considered a priority, even if it may not seem like an immediate emergency. The cruise control system is designed to enhance driving comfort and efficiency, and its failure could signal deeper issues within the vehicle's electronic systems or sensors. Ignoring this problem could lead to more significant complications, such as affecting the vehicle's overall performance or safety features. For DIY enthusiasts, diagnosing the issue early can save time and money, as it prevents further damage that might require more extensive repairs. While you may be tempted to delay fixing the cruise control, doing so could result in increased driver fatigue during long trips and decreased fuel efficiency, ultimately compromising your driving experience. Therefore, it is advisable to investigate and resolve any cruise control malfunctions promptly to ensure your GMC Savana 2500 remains safe and reliable on the road.
