There are two filaments in the lamp. One for the tail light and a brighter one for the brake light. First thing I would do is pull out the bulb and check the filaments to be sure that they are both good. If the lamp appears to be good you can have someone hold the brake pedal down and check for voltage.
Check the bulb--should be a double filament one may be burnt out(Smaller filament is Stop light) and backfeeding when tail lights are not on Check the socket may have some corrosion Check the ground - Check the bulb--should be a double filament one may be burnt out(Smaller filament is Stop light) and backfeeding when tail lights are not on Check the socket may have some corrosion Check the ground -
Just a side note Some brake light problems are also caused by a faulty turn signal switch. I was having problems in my 97 firebird where one side would work then not work and then the other side would work and not work. After a long check of the whole system it turned out to be the turn signal switch. I replaced it and all is good now!
Great chance it is a bad bulb. There are 2 filaments and one is probably bad.
make sure u got a twin lement bulb one element is for tail light other is for brake light sounds like u just put wrong bulb in
brake light switch bad check for continuity at the fuse then the switch, but yeah bad switch. Kongkit Raggan-Supatanampon
The bulbs and or sockets are dirty/corroded and need either cleaned or replaced. The corrosion causes the light to not have a good ground contact, therefore the circuit's power is finding it's way through other systems.
my '94 grand 'kee has a similar problem. The warning tone comes on and STAYS ON, even though the dashboard diagnostic display doesnt show anything is wrong. It will cut out intermittently, and then quit for no reason after about 20 minutes. Drives my wife nuts. ( I drive a Ford Ranger lol)
Most likely your car battery is completley dead.
my back brake lights don't work, but the brake light on the back door does what could be wrong
wrong bulbs or bad earth
Brake light switch near brake pedal
=I don't know about the brake lights. I know that most cars, when you turn it off and get out, the head lights and main backlights stays on for a while but then goes off. The brake lights? Maybe it's the way that car is or something is wrong with the brake or you have it on wrong.=
Have you checked your bulbs ? The tail light / brake light bulb has 2 wires inside it In my case I have had to change each bulb because the brake light portion did not work but the tail light portion of the bulb did ( I'm assuming that your front park lights are working )
Chjeck the brake light switch located somewhere on the brake pedal lever.
Have you checked all the lights? Reverse lights, tail lights and brake lights?
Fuse or brake light switch are most likely.
why my jeep brake light on all time
What year is the Ford Explorer ? There could be a separate fuse for the lower brake lights
the engine is going out. sell the car
It could be the brake light switch, usually mounted on the brake pedal.
