Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the cruise control fuse using the fuse diagram.
Remove the fuse using a fuse puller and visually inspect it for damage. Replace if necessary.
Reconnect the battery and check if the cruise control is operational.

3. Check and Replace the Brake Light Switch

Locate the brake light switch, usually positioned above the brake pedal.
Disconnect the electrical connector and remove the switch using a socket set.
Test the switch for continuity with a multimeter while pressing the switch.
Replace the switch if it fails the continuity test.
Reinstall the new switch, reconnect the electrical connector, and check the cruise control functionality.

4. Inspect Cruise Control Actuator and Cable

Open the hood and locate the cruise control actuator, typically mounted near the throttle body.
Visually inspect for any physical damage or disconnections in the actuator and cable.
If damaged, remove the actuator using a socket set, noting the mounting positions.
Install a new actuator by reversing the removal steps, ensuring all connections are secure.

5. Test Cruise Control Switches

Remove the steering wheel cover to access the cruise control switches.
Use a multimeter to test the continuity of each switch while pressing them.
Replace any non-functional switches with new ones to restore proper operation.
Reassemble the steering wheel cover.
