No brake lights or blinker

Did you replace any parts of the system? In any case, it sounds like a short and the lights are getting direct power. The light switch itself may be bad. You may want to use a light tester to check the wires of the entire assembly.

ACTUALLY!!!...r u sure it's the back running lights and not ur brake lights??? There is a brake/cruise/ABS control switch connected to the brake pedal...way up under the dash. If this switch, which controls the brake lights, cruise control and ABS system isn't aligned properly, then the first and most obvious condition is the brake lights stay on. Try going for a drive and see if the cruise control works. Also, pull out on the brake pedal and have someone at the rear of the pick up n see if the lights go out.

BTW, the blinkers are a different matter...see if the light question is brake lights or not, first.
