The cruise control in a 2008 Silverado may not be working due to various factors, including blown fuses, issues with the brake pedal switch, problems with the vehicle speed sensor (VSS), or malfunctions in the throttle actuator control module (TAC). Identifying the specific cause is crucial for effective troubleshooting and repair.
In this blog post, we’ll discuss the common issues that can cause cruise control to malfunction in your 2008 Silverado and provide practical solutions to get it back on track.
What Is The Cruise Control Fuse On A 2008 Chevrolet Silverado?
In a 2008 Chevrolet Silverado, the cruise control fuse is typically in the vehicle’s box or fuse panel. It may be labeled as “Cruise,” “Speed Control,” or similar. The exact labeling and location of the cruise control fuse can vary depending on the specific model and trim of your Silverado. To identify the fuse, refer to your vehicle’s owner’s manual or the fuse box cover, which often includes a diagram indicating the purpose and location of each fuse. If you’re uncertain, it’s advisable to consult the owner’s manual or seek assistance from a qualified mechanic to locate and replace the cruise control fuse if needed.
Reasons for 2008 Chevy Silverado Cruise Control Not Working
Cruise control is a convenient feature many drivers appreciate for long highway journeys. However, when your 2008 Chevy Silverado’s cruise control system isn’t functioning as expected, it can be frustrating. There are several potential reasons for this issue, and we’ll explore five common ones:
1. Blown Fuse:
A blown fuse is a frequent cause of cruise control failure. In the 2008 Chevy Silverado, the cruise control system relies on a specific fuse to operate. If this fuse blows, it can disrupt the system’s power supply. To address this, check the cruise control fuse in the fuse box, which is typically labeled as “Cruise” or “Speed Control.” If the fuse is blown, replace it with a new one of the same amperage.
2. Brake Pedal Switch:
The brake pedal switch is an essential safety component in the cruise control system. It’s designed to disengage the cruise control when you apply the brakes. If this switch malfunctions or fails, it can prevent the cruise control from engaging. Inspect the brake pedal switch for proper adjustment and operation. If it’s faulty, consider replacing it.
3. Vehicle Speed Sensor (VSS):
The Vehicle Speed Sensor sends speed-related data to the engine control module and the cruise control system. If the VSS fails, the cruise control may not function correctly. Diagnose the VSS for any issues and replace it if necessary.
4. Throttle Actuator Control Module:
The Throttle Actuator Control Module (TAC) is crucial in managing the cruise control system. If it encounters problems or malfunctions, it can disrupt the cruise control’s operation. Diagnosing and repairing the TAC module is essential for resolving cruise control issues.
5. Software and Calibration:
Sometimes, cruise control problems can be attributed to software issues or calibration errors. If your vehicle has had software updates or any changes made to its electronics, it might affect the cruise control’s operation. In such cases, recalibrating the system or updating its software may resolve the issue.
Troubleshooting 2008 Chevrolet Silverado Cruise Control Not Working Issue
When your 2008 Chevy Silverado experiences cruise control problems, it’s essential to perform systematic troubleshooting and find appropriate solutions. Here’s a step-by-step guide to help you address these issues:
1. Check the Cruise Control Fuse:
Begin by inspecting the cruise control fuse in the fuse box. Ensure it’s not blown and is of the correct amperage. If blown, replace it with a new fuse of the same rating.
2. Examine the Brake Pedal Switch:
The brake pedal switch is crucial for disengaging the cruise control when you apply the brakes. Check its adjustment and operation. If it’s not functioning correctly, consider replacing it.
3. Diagnose the Vehicle Speed Sensor (VSS):
The VSS provides speed-related data to the cruise control system. Examine the VSS for any issues, such as damaged wiring or connections. If necessary, replace the VSS.
4. Inspect the Throttle Actuator Control Module (TAC):
The TAC module plays a significant role in cruise control operations. If it’s faulty or malfunctioning, it can disrupt the system. Have the TAC module inspected and repaired by a professional if needed.
5. Recalibration and Software Updates:
If you suspect software or calibration issues, consult your dealership or a qualified technician. They can recalibrate the system or update its software to ensure proper cruise control functionality.
6. Professional Diagnosis:
If the problem persists or you’re uncertain about the diagnosis and repair, seek the assistance of a professional mechanic. They can conduct in-depth diagnostics and recommend the most suitable solutions.
Preventive Measures:
- To avoid future cruise control issues, regularly inspect and maintain your vehicle’s electronic components, such as the brake pedal switch, VSS, and TAC module.
- Ensure you’re using the correct type of fuses and replace any blown fuses promptly.
- Stay current with your vehicle’s maintenance schedule to prevent potential problems related to the cruise control system.
Where Is The Cruise Control Fuse On 2008 Chevrolet Silverado?
In a 2008 Chevrolet Silverado, you might be looking for a cruise control fuse if you’re experiencing issues with your cruise control system. While the fusebox typically doesn’t have specific labels for the cruise control, there are ways to locate it.

Check this location to see if the fuse is intact and not blown.
If you find that the fuse appears damaged, replace it with a new one of the same amperage rating. It’s also a good practice to inspect other fuses in case they contribute to any issues with your vehicle’s functions. Repair or replace any faulty fuses as needed to ensure proper functionality.
