SOURCE: mustang brake lights dont work

this car has a brake light switch on the pedal check for power in and out. if in and not out change switch. also I believe their is a relay under the hood . then check to see if the multifunction and hazard switch control brake lights i cant remember if they do like gm's but i am also almost sure they do the multifunction is your turn signal wiper arm that goes into steering wheel . after you check the brake switch and relay have some one jiggle the hazard and multi while pressing the brakes see if they come on. you can call ford and ask them about the multi and hazard .

Why would the brake lights go out in my 2003 Ford Mustang, when all of the fuses are still good?

It could be a number of things. I would check the brake light switch. Look upward from where you put your foot on the pedal, you will find the switch. Test for voltage on both sides of the switch. There should be power to one side of the switch at all times. When you push the brake pedal down, the power should flow to the other side (wire), of the switch. Basically, if you have power coming in to the switch, and you DON'T have power going out of the switch (with the brake pedal depressed), then it's the switch.

03 mustang dash and tailights are working

if you installed an aftermarket stereo, the tail lights run through the illumination. make sure all wires are hooked hot to hot and ground to ground. if you installed it while battery was hooked up and touched a wire, most likely blew a fuse

2004 ford mustang mach 1 brake lights dont work dont have manual to change the fuse

I don't believe there is a separate fuse for the high-mount brake light. Never was on older cars, that brake light is just spliced into the rear brake lights. Have you checked the bulb?

ford has a saftey in which if your brake switch is bad, brake light fuse is bad it wont let you shift out of park basically what it tells you if you have no brakelights, also in order to shift the car the brake pedal must be depressed

Hi, I have power to back up lights, turn signals and tail lights, but no brake lights, what should I check? Joe

first try a new bulb on one side of the brake light at the rear if still not working then i suspect it will be the brake light switch assuming your fuses are all good.

Brake lights stopped working 1998 mustang

Fuse panel is under the dash also as I have found with my own graceful daughter, there is a brake light switch that connects to the brake pedal itself. It is hard to get to and even harder to see but a lot of times these switches get bumped and they can not make connection when the brake pedal is depressed. Hope this helps

2003 mach1 mustang, no brake lights, no cruise control

Check the fuses, if they are blown, make sure they are the right size. If not, do not use bigger fuses than the circuit is supposed to have. If they are too small, use the correct size. If they are, do you have any extra equipment using the same circuit? Like a stereo or GPS or an alarm system? Move them to a different circuit. Check the relays to see if they are defective. Check all the bulbs to make sure they are the right ones too. Make sure they are in the right way. Check grounding wires, make sure they have good connections.
