How do you fix the cruise control on a 98 Volvo S70?

To fix the cruise control on a 1998 Volvo S70, first check the fuse associated with the cruise control system, as a blown fuse can prevent it from functioning. Inspect the brake switch, as a malfunction here can disable the cruise control when the brake is applied. Additionally, examine the throttle cable for any damage or disconnection, and ensure the cruise control module is receiving power. If these components are in good condition but the issue persists, consider consulting a professional for further diagnostics.
