1996 FORD F150 WHEN YOU TURN ON THE FOUR WAYS THE LIGHTS WONT WORK. CHANGED THE SWITCH STILL WONT WORK, CHANGED FUSES WHAT COULD BE THE PROBLEM

Sounds like the brake light switch under the brake peddle change it out should be okay.under 15 bucks at the parts store

The other flasher fuel will be under the hood in the main fuse contol box.

You may need to replace the flasher,the turn signals use a different flasher but the same wireing so that would be the first place i would start.

Hello heinz2127: My name is Roger and i will help you. The rear brake wires are green and yellow. They also are the turn signal wires. The brake lights work through the turn signal switch.The turn signal switch has logistics for determining which side is blinking so as to make the opposite side to show park brake light.Check the fuse box for a blown fuse. Look at the fuse box under the hood. Also try this. Turn on the four way flashers. Step on the brake pedal . The lights should stop flashing If not I would replace the turn signal switch.

Possible cause is that your fuse is blown, or switch is malfunctioning.
Try to check the fuse first.

bad ground on tail lights

If you have trailer lights make sure you don't have a short in the connector or harness. You obviously have a short somewhere after the fuse. Try unlpugging each running light. to see if its in the light connecter. also check the side markers

its probably the headlight switch. the headlights work, but the taillights don't, and the instrument panel lights don't work either. i have had this on another ford model.

check fuse number 7 in Engine Compartment Fuse Box , if its ok you need change turn signal switch
