Electrical??????

2000 work van... All bulbs are good... Reverse lights dont work, Right Blinker stays on but when it decides to blink the radio and dash lights blink with it.. Hazards stay steady on but do the same when they decide to work... Left Blinker works... When you tap the brake pedal you here the door open ding and the dash lights flash.....

Bad body ground.... somewhere. Check battery negative cable, take it apart and shine it up with a file or sandpaper, then reinstall and tighten. Check body grounds near the head lamps on radiator support, both sides. Take it apart and shine up the connectors with a file or sandpaper and tighten it up. Check all body grounds and clean and tighten them. Post your results.

Ugh well i dumb ass put the wrong bulb in the right blinker... Reverse lights still dont work bulbs are fine now....

Check fuses and check for battery voltage and ground at the back up light sockets with the key on and the transmission in reverse.
