Repair Instructions:

Reset OBD-II Codes (if applicable):

  - Reconnect the negative battery terminal.
Inspect/Replace Cruise Control Module (if necessary):
- If no issues are found with the switch and the problem persists, the cruise control module may need inspection or replacement.
  - Locate the cruise control module (usually found near the engine bay or under the dash).
  - Check for loose connections or damaged wiring.
  - If necessary, replace the module by disconnecting it and installing a new one.
Test Drive:
- After all repairs have been completed, take the vehicle for a test drive to check if the cruise control is now functioning properly.
