I have a 1999 Oldsmobile Aurora with 90,000 miles that the headlights will blink on and off in an irregular pattern. Even when the vehicle is on and running, it will continue to do the same thing. If you turn the headlight switch on, it will stop the blinking but I can hear a relay in the HDLMP auto control module clicking. I have already ruled out the module. I am hoping you might have an idea of what might be causing my problem.
