There should be a switch under the brake pedal. This should opearate the brake lights. It is also not impossible for both the brakelight lightbulbs to blow at the same time.

Sometimes a trunklid slamming can break the filaments. Check the switch under the brake pedal first and remember to look at the backwindow light to see if it is working. The brake pedal switch is simple to install. The rear window light may work if the tailight wires are unplugged.

I have a 2005 Dodge Durango. My brake lights are the only lights not working all 3. Every other light works but the 3 brake lights. I've changed the all 3 brake light bulbs and the brake light switch....


If fuse 25 under the hood is good, you have a wiring issue. Are you getting power at the brake light switch? If yes, trace the wires from there to he rear of the truck. If not, trace forward to the fuse.

Third brake light does not work after changing the bulbs


If some of the lights work then you probably don't need to change the light assembly. My first guess would be a burnt out fuse. Look for the fuse box and remove the cover. Usually on the inside of the cover it will have a diagram for all the fuses and you can find the one for the brake lights. Some vehicles have relays that are fried and these may be under the hood. Just look for a black box which contains electrical relays and other fuses. The last thing I can think of is a switch that is right above the brake pedal. When you apply the brake a small plastic or metal extends and this is what makes your brake light come on. www.lightdeal.co.uk

How do i fix the brake lights on my mercury sable. all the other lights work fine


Does your car have the `lamp out'indicator system? It's more complicated.
My manual shows fuse #28 , a 15 amp fuse powers the brake bulbs.Is this the one you changed?
A bulb can be out for a long time and you don't notice it,then the other burns out and you think they both went out at the same time,but they might not have,see?
So check the bulbs and make sure you got that brake switch installed correctly. don-ohio (:^)

My daughters 1998 honda accord ex keeps blowing fuses she is having to replace the brake light fuse after we replaced the brake light switch when she changed the fuse last the horn blew and she was shocked...


The horn and rear brake lights are on the same fuse. Eventually the horns rust out like on my 1998 CRV. Once I replaced the horns, I could put in a new fuse without it blowing every time I sounded the horn. Problems still remain, namely: the cruise control does not engage and the remote start only starts the engine that runs for two seconds then dies. Still looking for an answer. It's a "Code Alarm" with Codestart dated 11/24/99.

I have a1993 Fird Taurus wagon. The brake lights


Check all fuses with a test light with key on.
This is the best way to do it on Fords.
Change all blown fuses.
Are the brake light BULBS OK?
This is the more common cause of.....no brake lights.
....and don't forget the brake light switch if all this fails.
