The most common reasons a 1998 Lincoln Continental 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 1998 Lincoln Continental 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 steps to diagnose the non-functioning cruise control in a 1998 Lincoln Continental?

To effectively diagnose the non-functioning cruise control in a 1998 Lincoln Continental, it's essential to adopt a systematic approach that begins with the simplest potential issues before progressing to more complex diagnostics. Start by checking the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable problem. Next, inspect the cruise control switch located on the steering wheel to ensure it is operational, since a malfunctioning switch can prevent engagement. Following this, examine the brake pedal switch, which is crucial for disengaging the cruise control when brakes are applied; a faulty switch here can also disable the system. After these initial checks, test the speed sensors to confirm they are accurately relaying information to the cruise control module, as faulty sensors can lead to operational issues. Utilizing a diagnostic scanner to check for error codes can provide further insights into any underlying problems. Finally, inspect the wiring and connections for any signs of damage or looseness, as these can disrupt the cruise control's functionality. By methodically addressing these areas, you can effectively identify and resolve the issues affecting your cruise control system.

What are the common causes for the cruise control not working in a 1998 Lincoln Continental?

When dealing with a non-functional cruise control system in a 1998 Lincoln Continental, it's essential to understand the common problems that could be causing the issue. One of the primary culprits is a failed control module, sensor, or switch, which can disrupt the communication necessary for cruise control to operate. Additionally, throttle actuation problems may prevent the system from maintaining speed, while a faulty vacuum actuator can lead to a complete failure of the cruise control function. It's also important to check for blown fuses, as these can cut power to the cruise control system, rendering it inoperative. Other potential issues include a malfunctioning brake light or brake switch, which can inadvertently signal that the vehicle should not engage cruise control. Lastly, if the check engine light is illuminated or if there are underlying engine problems, these can also inhibit the cruise control from functioning properly. By systematically diagnosing these areas, DIYers can effectively troubleshoot and resolve the cruise control issues in their Lincoln Continental.

How urgent is it to repair the non-functioning cruise control in a 1998 Lincoln Continental?

While the non-functioning cruise control in a 1998 Lincoln Continental may not seem like an urgent repair, it is essential to recognize the implications of neglecting this issue. Cruise control plays a significant role in enhancing safety during long drives by allowing the driver to maintain a consistent speed, which can help reduce fatigue and the likelihood of accidents. Additionally, the convenience of cruise control cannot be overlooked; it allows for a more relaxed driving experience, particularly on extended trips where constant speed adjustments can become tiresome. Furthermore, from a financial perspective, ensuring that all vehicle features, including cruise control, are operational can positively impact the car's resale value. Prospective buyers often look for well-maintained vehicles with all systems functioning properly. Therefore, while it may not be an immediate concern, addressing the cruise control issue promptly can lead to a safer, more enjoyable driving experience and help preserve the vehicle's value over time.
