Why is the cruise control on my 1988 Cadillac Brougham not working When I turn on the switch the amber light comes on and the green light works showing cruise engaged The fuse is good?

If the amber light is on and the green light indicates that the cruise is engaged, the issue may lie with the cruise control actuator, which could be malfunctioning or not receiving the proper signals. Additionally, check the brake pedal switch, as a faulty switch can disengage the cruise control when the brakes are applied. Lastly, inspect the wiring and connections for any damage or corrosion that may affect functionality. If these components are in good condition, further diagnostic testing may be necessary.
