2000 Mercury Marquis signals and flashers

Hi, many mounths ago signals started to blink faster. Looked at bulbs and they were fine. Worked like this, blinking fast and slower, for a while. Now they started to not work at all on and off. Flashers had same results. Looked for flasher relay but the the blinkers noise was comming from a light control module. Checked connections, played with flashers and turn signals, but now nothing is happening no noise or lamps. Also if flasher button is depressed the brake lights dont work. Please advise thank you
