How to Troubleshoot: 2003 Ford Expedition Cruise Control Not Working

The cruise control on your 2003 Ford Expedition is a convenient feature that can help you maintain a steady speed on long road trips. However, if your cruise control isn’t working, it can be a major inconvenience.

There are a few different things that could cause your cruise control to stop working. In this article, we’ll walk you through the steps to troubleshoot the problem and get your cruise control back up and running.

Step 1: Check the Cruise Control Switch

The first thing you should do is check the cruise control switch to make sure it’s turned on. The cruise control switch is located on the steering wheel. It’s a small button with a raised Cruise logo.

To turn on the cruise control, press the cruise control switch. The switch will light up, and you’ll hear a chime.

If the cruise control switch is turned on and your cruise control is still not working, move on to the next step.

Step 2: Check the Cruise Control Bypass Switch

The cruise control bypass switch is a small button located on the brake pedal. It’s a small button with a raised Off logo.

If the cruise control bypass switch is engaged, your cruise control will not work. To disengage the cruise control bypass switch, press the button.

If the cruise control bypass switch is disengaged and your cruise control is still not working, move on to the next step.

Step 3: Check the Cruise Control Fuse

The cruise control fuse is located in the fuse box under the hood of your Expedition. The fuse box is a black box with a red cover.

To check the cruise control fuse, open the fuse box and locate the fuse labeled Cruise Control. The fuse should be a 10-amp fuse.

If the cruise control fuse is blown, replace it with a new fuse.

If the cruise control fuse is not blown and your cruise control is still not working, move on to the next step.

Step 4: Check the Cruise Control Throttle Position Sensor

The cruise control throttle position sensor is a sensor that tells the cruise control system how fast your engine is running. The sensor is located on the throttle body.

To check the cruise control throttle position sensor, you’ll need a voltmeter.

1. Turn off the engine and disconnect the negative battery cable.
2. Locate the cruise control throttle position sensor on the throttle body.
3. Disconnect the connector from the sensor.
4. Connect the voltmeter to the terminals on the connector.
5. Start the engine and let it idle.
6. The voltmeter should read between 0.5 and 4.5 volts.

If the voltmeter reading is not within the specified range, the cruise control throttle position sensor is bad and needs to be replaced.

Step 5: Check the Cruise Control Control Module

The cruise control control module is a computer that controls the cruise control system. The module is located under the dash on the passenger side.

To check the cruise control control module, you’ll need a diagnostic scanner.

1. Connect the diagnostic scanner to the OBD-II port under the dash.
2. Turn on the ignition.
3. The diagnostic scanner will display a list of codes.
4. Look for any codes that relate to the cruise control system.

If there are any codes, the cruise control control module is bad and needs to be replaced.

Step 6: Take Your Expedition to a Mechanic

If you’ve tried all of the steps above and your cruise control is still not working, it’s time to take your Expedition to a mechanic.
