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.
To effectively diagnose the non-functioning cruise control in your 2012 GMC Savana 3500, begin with the simplest checks to rule out common issues. Start by inspecting the cruise control fuse located in the fuse box; a blown fuse can easily disrupt the system's functionality. Next, examine the cruise control buttons on the steering wheel to ensure they are not stuck or damaged, as this can prevent engagement. Utilizing an OBD-II scanner to check for error codes can provide valuable insights into any underlying electronic issues. Additionally, verify the operation of the vehicle speed sensor, which is essential for cruise control to function correctly. Don’t overlook the brake pedal switch; a malfunctioning switch can inadvertently disable the cruise control. Finally, inspect all wiring connections related to the cruise control system for any signs of damage or looseness. By following this structured approach, you can systematically identify and address the root cause of your cruise control issues, making your DIY troubleshooting more efficient and effective.
When dealing with a malfunctioning cruise control system in a 2012 GMC Savana 3500, it's essential to understand the common problems that could be at play. One of the first areas to check is the brake pedal switch, as a faulty switch can prevent the cruise control from engaging, since it is designed to deactivate when the brake is pressed. Additionally, a malfunctioning speed sensor can lead to incorrect speed readings, which may disrupt the cruise control's functionality. It's also wise to inspect the fuses related to the cruise control system, as a blown fuse can halt its operation entirely. If these components check out, consider the cruise control module itself, as a defect here can be a significant factor in the system's failure. Lastly, don't overlook the possibility of vacuum leaks in the engine, which can adversely affect the cruise control's performance. By systematically examining these areas, you can effectively troubleshoot and potentially restore the cruise control functionality in your vehicle.
Addressing the non-functioning cruise control in your 2012 GMC Savana 3500 should be a priority, even if it may not seem urgent at first glance. While the immediate drivability of your vehicle may not be compromised, neglecting this issue can lead to more significant problems down the line. A malfunctioning cruise control system can indicate underlying electrical issues that, if left unchecked, could escalate and affect other critical components of your vehicle. Moreover, the convenience of cruise control enhances your driving experience, particularly on long trips, by reducing fatigue and improving fuel efficiency. Therefore, it is wise to inspect the system promptly, as doing so not only helps maintain the vehicle's performance but also safeguards against potential safety risks. By addressing the cruise control issue sooner rather than later, you can ensure your vehicle remains reliable and retains its value, making it a worthwhile endeavor for any DIY enthusiast.
