The most common reasons a 1997 Dodge B2500 cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 1997 Dodge B2500 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 throttle position sensor fails, the engine's computer tends to overcompensate with fuel, leading black exhaust coming from the tailpipe. There is a strong possibility of engine misfires, and the check engine light will come on.

Throttle position sensors can also develop "dead spots," or certain places along the throttle curve where it doesn't get a reading. When this happens, the above symptoms can occur but then stop when you further press or let off the gas pedal.

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 steps to diagnose the non-functioning cruise control in a 1997 Dodge B2500?

When diagnosing the non-functioning cruise control in a 1997 Dodge B2500, it's essential to adopt a methodical diagnostic approach. Begin by checking the fuse associated with the cruise control system, as a blown fuse is a straightforward issue that can easily be resolved. Next, inspect the cruise control buttons on the steering wheel to ensure they are operational, as malfunctioning buttons can hinder functionality. Following this, verify the speed sensor, which plays a crucial role in relaying speed information to the cruise control system; a faulty sensor can disrupt its operation. Additionally, examine the vacuum lines for any leaks or damage, as these can significantly impact the system's performance. Finally, consider using a diagnostic scanner to check for error codes that may provide insights into specific issues affecting the cruise control. By following these steps, you can effectively diagnose and potentially resolve the cruise control problems in your Dodge B2500.

What are the common problems that could cause the cruise control to stop working in a 1997 Dodge B2500?

When troubleshooting the cruise control system in a 1997 Dodge B2500, it's essential to consider several common problems that could lead to its failure. One of the primary culprits is a faulty cruise control module, which can disrupt the entire system's functionality. Additionally, issues with the sensor may prevent the cruise control from engaging properly, while malfunctions in the throttle system can also hinder its operation. It's important to inspect the vacuum actuator and its associated hoses, as damage here can significantly impact performance. Furthermore, a damaged cable connecting the actuator to other components may be the source of the problem. Don't overlook the possibility of a blown fuse, which is a frequent cause of cruise control issues. Lastly, a faulty brake light or brake switch can interfere with the cruise control system, as can any engine-related problems indicated by an illuminated check engine light. By systematically checking these components, you can effectively diagnose and resolve the issues affecting your cruise control.

How urgent is it to address the non-functioning cruise control in a 1997 Dodge B2500?

When it comes to the non-functioning cruise control in a 1997 Dodge B2500, addressing the problem should be a priority, even if it may not seem urgent at first glance. While the immediate safety risks may be minimal, the convenience of cruise control is particularly valuable during long drives, allowing drivers to maintain a steady speed without constant manual adjustments. Ignoring this issue can lead to increased driver fatigue and discomfort, especially on extended trips. Moreover, a malfunctioning cruise control system could indicate underlying problems that, if left unchecked, may escalate into more significant and costly repairs down the line. Therefore, it is wise to have the system inspected and repaired by a qualified mechanic to ensure not only the functionality of the cruise control but also the overall safety and comfort of your driving experience. Taking prompt action can help you avoid potential complications and enhance your vehicle's performance on the road.
