Something you may not realise is that the brake light bulb is often one bulb with two elements. One of the elements will be for the brake and the other will be for the tail lighting for example so,when tested, the actual bulb will still light up because the second element is unaffected. Make sure that the 'blown' bulb that you are actually changing is not in fact your fog lamp. This will not automatically light up when you test your lights as you have to operate this light separately (similarly to indicator lights). So the fog lamp bulb will appear to be the only one not lit up when you test your lights. Find the bulb with two elements inside and change that one. Sounds obvious (and may be obvious to many) but it's a common mistake. Hope this helps!.
brake light switch is above the brake pedal under the dash
Blinkers can work without brake lights. Brake lights are activated by a switch that is switched by the brake petal and the turn signals are acivated by your turn signal switch on your steering column. The two are two separate circuits. I suggest you check out the switch on your brake pedal to see if it is working properly. It must have 12 volts applied to one side when it is not acitvated and 12 volts should be on both sides when it is activated. When the 12 volts is on both sides of the brake switch, it should apply 12 volts to your brake lights and then they should come on.
Change out the switch. Bad switch!!
Check the brake light fuse. If you have 12 volts at the brake light switch I would suspect the signal light switch is at fault.
Bulbs? Sockets? Steering column switch?
have you check the tail light fuse to see if it is blown. other possiblly is the headlight switch.
The problem might not be a fuse. There is a switch which activates the brake lights when the brake pedal is depressed. This switch is usually mounted under the dash, near the top of the brake pedal lever. Insure that this switch is free to move physically, and test it to see if it is switching electrically.
Check the bulbs. These bulbs are a combination tail light & brake light. Even though the blinkers work, the brake light part might be burnt out. If these are okay, check the brake light switch. It's mounted on the brake pedal. Are the brake lights on all the time or they don't light up at all? if all the bulbs are fine, its more than likely the stop-light switch underneath the brake pedal.
IT COLUD BE A RELAY BOX multi function switch( turn signal, lites ect.)
whats the color circuit for the blinkers an break lights?
First, check all fuses. Then see if you are getting power to the bulbs. Then the next possibility would be the turn signal switch.
Turn signal switch is melting...replace the turn signal switch in the steering column.
