Brake lights dont work

Blown fuse ,bad headlight switch,or wiring issue.
the tail lights have there own fuse and are powered through headlight switch. Do the front running lights come on? If none of them work, switch could be bad if front work and rears dont, check bulbs and power to them when lights are on

Three places to look. 1) Brake lamp fuse, 2) Turn signal switch and 3) the brake pedal switch. Brake light power comes from the fuse up to the turn signal switch down to the brake lite switch on the brake pedal and then on to the light bulbs. Start by putting the 4 way flasher on. If the brake lites flash, then the bulbs are good. That eliminated the fuse too. so the problem is the other two.

For starters it is spelled "Brake" light...LOL . Sounbds like you may have a brake light switch that has gone out. In yor owners manual does it show more than one fuse for the brake lights? Most vehicles with a thrid/highmount brake light split the brake light power to either the left and third brake light and the right brake light or vice versa, or posibble 3rd brake light on its own fuse. I would check if all of the brake light including the 3rd brake light dont work. If no lights work at all it leans toward the switch which controls all or them to activate hence the brake light switch. It should be mounted on your brake peal arm or to the main base. The pedal lever activate the switch when you depress the brake pedal.

You have a failed brake lamp relay,this is located at the back right hand in the trunk at the quater panel.

I think there are 2 fuses for those switches. Fuse #11 & #39

Hope that works for you

The brake lights are routed through the signal light switch.
Looks like that will be the next switch to replace and the problem.

Not even the third eye? then the fuse is blown or all the bulbs are out or the brake light switch on the break pedal is bad wire off or broken( it breaks right off the plug then crosses then blows the fuse as the loose broken wire hits the brake pedel arm. Test the break pedal switch first if the third eye doesesnt work either. no power with a test light the fuse is blown or the wire broke ( the wire goes straight to the switch from the fuse and doesnt go anywhere elese. the other wire if hot should light the lights. Most of these wont come out of park without this working as the wire also turns on the park release but some Fords the park release sticks released and Ford made em that way as they didnt like the brake to get out of park law. If the brake lights dont work maybe you ought not be able to get out of park anyway till its fixed. the switch is hot on both wires with the switch pused down and the lights dont still work go after the third eye first if the bulbs are bad change em before you do the rest of the work. on cars with yellow turn signals the brake lights all work on the same wire but red only use three wires, but you didnt say the turn signales didnt work if they work and they are red you r on the way to the turn signal switch as the brake switch powers the turn switch with power then it splites it fot the two lights and adifferent switch circuit for the front hooks them all together for hazard. yellow turns in the back or even separt bulbs can mean blown bulbs ther too its old enought for all the bulbs to fail and the runs still work.

I have a 2001 Ford F150, my brake lights dont work. Ive replaced the bulbs, checked the fuses,and the brake switch on side of the brake pedal was replaced. I still dont have any brake lights. My third brake light works fine, along with my running lights,flashers, blinkers.

if all fuses and bulbs are ok get to the brake switch and see ifits stiff or stuck, if it just has two wires on it you could join themtogether to see if the brake lights come on though obviuosly dont leave them joined.Good luck davelee

check the fuse for the brake lights. The brake lights and siganl lights use the same bulb filament. The parking and running lights use a dimmer filament in the bulb. There are 2 filaments.
Your brake lights work through the multifunction switch which operates the signal lights. If the signal lights work, you may have a bad brake lamp switch which is on your brake pedal arm.
Let us know what you find.
