The most common reasons a 1999 Oldsmobile Bravada 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 1999 Oldsmobile Bravada 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.

A faulty cruise control module will simply result in deactivation of cruise control settings. This is because a detected error in the cruise control system could lead to hazardous driving conditions, so the module will be disabled, and the cruise control system warning light will be displayed. This will be a different message depending on make and model, and a warning light or message may be displayed on the driver instrument cluster.

What are the initial steps to diagnose the non-functioning cruise control in a 1999 Oldsmobile Bravada?

To effectively diagnose the non-functioning cruise control in your 1999 Oldsmobile Bravada, start with the simplest and most common issues. Begin by checking the vehicle's fuse box for any blown fuses, as this is often a primary cause of cruise control failure. If you find a blown fuse, replacing it may resolve the issue. If the fuses are intact, the next step is to consider the possibility of a malfunctioning switch or control module. In this case, you might want to consult a mobile mechanic who can provide a thorough diagnosis at your convenience. They can identify whether the problem lies with the control module, sensors, or throttle actuation. If the diagnosis points to a faulty switch, replacing it with a new one could be a straightforward fix that restores functionality to your cruise control system. By following these steps, you can systematically address the issue and potentially save on repair costs.

What are the common problems that could cause the cruise control to stop working in a 1999 Oldsmobile Bravada?

When troubleshooting the cruise control system in a 1999 Oldsmobile Bravada, it's essential to understand the common problems that may lead to its malfunction. One of the primary culprits could be a faulty cruise control switch, which may prevent the system from engaging or disengaging as intended. Additionally, a blown fuse can disrupt the electrical flow necessary for the cruise control to operate, making it another frequent issue to check. Vacuum leaks are also a significant concern, as they can interfere with the system's ability to maintain speed. Furthermore, a defective speed sensor can hinder the cruise control's performance by failing to provide accurate speed readings. It's also important to inspect the brake light switch, as any issues here can prevent the cruise control from functioning correctly. Lastly, a malfunctioning throttle cable can impact the system's ability to maintain a steady speed. By systematically examining these components, you can effectively diagnose and address the issues affecting your cruise control system.

How urgent is it to address the non-functioning cruise control in a 1999 Oldsmobile Bravada?

When it comes to a non-functioning cruise control in a 1999 Oldsmobile Bravada, the urgency of addressing the issue cannot be overstated. While it may not seem like an immediate safety concern, neglecting this problem can lead to more significant complications down the line. A malfunctioning cruise control system often signals underlying issues within the vehicle's electrical system or sensors, which could compromise overall performance. For DIY enthusiasts, it’s crucial to recognize that timely intervention can prevent further damage and costly repairs. By inspecting the cruise control system early on, you can identify potential faults and rectify them before they escalate. This proactive approach not only ensures your vehicle operates efficiently but also enhances your safety on the road. Therefore, while it may be tempting to delay repairs, addressing the non-functioning cruise control promptly is a wise decision that can save you time and money in the long run.
