Why 2004 Ford Expedition Cruise Control Not Working

The cruise control module is responsible for controlling the cruise control system. If the module is faulty, it can cause the cruise control to not work.

Cruise Control Switch Fault

The cruise control switch is used to engage and disengage the cruise control system. If the switch is faulty, it can cause the cruise control to not work.

The cruise control system is wired to the engine, the throttle body, and the brake pedal. If there is a problem with the wiring, it can cause the cruise control to not work.

How to Troubleshoot: 2004 Ford Expedition Cruise Control Not Working

The cruise control on your 2004 Ford Expedition is a convenient feature that can help you maintain a steady speed on long road trips. However, if your cruise control is not working, it can be a major inconvenience. There are a few things you can check to troubleshoot the problem and get your cruise control working again.

Step 1: Check the Cruise Control Switch

The first thing you should check is the cruise control switch itself. Make sure that it is turned on and that the button is not stuck. You can also try toggling the switch on and off to see if that fixes the problem.

Step 2: Check the Cruise Control Wiring

The next thing you should check is the cruise control wiring. There are a few wires that connect the cruise control switch to the cruise control system. These wires can become damaged or corroded over time, which can cause the cruise control to stop working.

To check the cruise control wiring, you will need to locate the wiring harness under the dashboard. Once you have located the wiring harness, you can use a voltmeter to check the voltage at each of the connectors. If there is no voltage at any of the connectors, then the wiring is damaged and will need to be repaired or replaced.

Step 3: Check the Cruise Control Throttle Valve

The cruise control throttle valve is a small valve that controls the flow of air to the engine. If the throttle valve is stuck or malfunctioning, it can prevent the cruise control from working properly.

To check the cruise control throttle valve, you will need to remove the air intake manifold. Once you have removed the air intake manifold, you can visually inspect the throttle valve. If the throttle valve is stuck or damaged, it will need to be replaced.

Step 4: Check the Cruise Control Control Module

The cruise control control module is the computer that controls the cruise control system. If the cruise control control module is malfunctioning, it can prevent the cruise control from working properly.

To check the cruise control control module, you will need to use a diagnostic tool to scan the system for codes. If there are any codes, they will help you identify the problem with the cruise control control module. If the cruise control control module is faulty, it will need to be replaced.

Conclusion

These are the four most common causes of a cruise control not working on a 2004 Ford Expedition. By following these steps, you can troubleshoot the problem and get your cruise control working again.
