94 Cavalier

The brake lights and blinkers are not working. The fuses are still good. A few months ago I had to add brake fluid at least 3 times. When the brake lights and blinkers stopped working the ABS light began blinking on the dashboard. I need to know what to do. The police stopped me which is how I found out about these problems.

You need a mechanic to fix the brakes. You have a dangerous condition where you have to add brake fluid. The brake switch may not be working.
When you get the brake system repaired, the ABS light may stop blinking.
