Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery cable to ensure safety.
Allow the vehicle to cool down if recently driven.

2. Check 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 with a fuse puller or pliers.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.

3. Inspect and Replace Brake Switch

Locate the brake switch, typically mounted above the brake pedal.
Disconnect the electrical connector from the brake switch.
Test the switch with a multimeter; it should show continuity when the pedal is pressed.
If faulty, remove the switch by unscrewing it and replace it with a new unit.

4. Test Cruise Control Switch

Remove the airbag module from the steering wheel (if necessary) to access the cruise control switch.
Disconnect the wiring harness from the cruise control switch.
Use a multimeter to check for continuity on the switch when pressed.
Replace the switch if it does not function properly.

5. Inspect Cruise Control Actuator

Locate the cruise control actuator under the hood.
Disconnect the actuator's electrical connector.
Check for proper voltage supply to the actuator with a multimeter.
If no voltage is detected, trace back to the cruise control relay and wiring for issues.

6. Reconnect Everything

Reconnect all connectors and components that were removed.
Reconnect the negative battery cable.
Ensure all tools are removed from the engine bay.
