There is a switch under the dash for the Brakes. If this is the part they are replacing it can be due to physical damage caused by shoes hitting it. If you can check the repair bill find out if the switch is broken or burned out each time it was replaced.

If the switch is burning up, you need to trace the Brake wiring to the 3 fixtures. The high fixture and both taillights. Your problem would be bad light sockets or a bad wire to the brake. You are just operating about 3 lightbulbs, which at best is maybe 3 Amps. But if the power is grounding through a bad wire or bad socket, it will draw as much as it takes to melt the connection.

Don't know how important it is to you to know if your feet or someone else's feet are hitting the underdash switches. You could put ATV blue on the switch and it would rub off on the shoes hitting the switch. But it could make a mess on a carpet or start a War.

I hope you find my solution very helpful.

Why does my brake wire burn in half on my 2000 mustang?


Very strange. If circuit is pulling enough amps to burn up wire, one would expect fuse to blow. Is it possible something else is heating the wire, such as heater vent hose leaking, courtesy lamp bulb too close, other such? Could be that Hot Foot you are driving with,lol.

Hi Nadeem

I had a similar problem with my Toyota Hilux, it turned out to be the brake light switch. While driving, dab the breaks just enough to trigger the brake lights, if your motor cuts out then it could be the brake light switch

Have 03 mustang brake light switch went out 3 times within a short time of each other, they replaced it at no charge each time but why does it go out so frequently, as a matter fact it went out again today


Hi, because there is no relay in the circuit, all the lamp power passes thru that switch. Recommend you check the stop light bulbs to make sure they are the low wattage bulbs specified for your car. The higher wattage bulbs will fit in, but they draw too much current. Please let me know if you have any questions, and thanks for using FixYa.

2006 ford mustang front right parking light stays on at all times and drains the battery is there a stuck switch?


With only one light staying on, it won't be a switch.

To start troubleshooting, swap the 2 front bulbs. If the problem follows the same bulb, replace the bulb. If it doesn't, you may have a power wire issue somewhere and would take a little more troubleshooting.

If the bulb filament is too close to each other, it can keep it on. I had it happen on a previous vehicle.

If this doesn't get you a solution, please come back.

The stop light switch keeps going out on my 1998 ford mustang. Is there a known root problem for this? I have had to replace it four times in the past 4 years, the most recently being 1 month ago, and now...


Make sure switch is installed properly and it has the proper bushing in it. make sure the hole on the hydroboost push rod isn't damaged and crushing switch internals when braking. hope this helps

My 20002 mustang v6 its automatic


To shift from "P" to "R", there is a swicth that allows the shift button on the shift lever to be depressed. For this switch to work, the ingnition switch must be "ON" and the brake pedal depressed. If all yor brake lights went out (or if your brake switch on the pedal fails to work), then the shift switch wont work and you can not shift out of "P".
