you may have a faulty turn signal switch may also try to test the brake switch located on the brake pedal with a test light to do this locate the 2 wires on the switch one will b hot the other not with the key on depress the brake pedal and check 2 seee if the one wire that wasnt hot, is now hot if it is then the switch is good good luck cause that turn signal switch is about 300$
If you have the same bulb for brake and signal, brake light power needs to be interrupted by the signal lights, The brake circuit has to go through the signal light switch so the problem could be there.
the turn signal switch is probably bad
Assuming the signal lights still work, no. But a bad brake light switch or a blown brake light fuse could.
Check the brake light fuse, the bulbs, the brake light switch and last, check the signal switch.
Problem may be in the steering column turn signal not cancelling completely - try "jiggling" stalk and have assistant watch brake light
Check and make sure you have the correct bulb. The turn signal/brake light is a dual element bulb and if you have a single element it does not work properly.
Bad fuse or bad brake light 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.
The brake light switch on a Nissan is located just behind the brake pedal. It sends a signal to the brake lights when the pedal is pressed to turn them on.
Your question was a little unclear, does the brakelight work when the headlights are off but not when they're on? If that's the case, it's a ground problem. Check the ground to the tail light/brake light assembly. If the brake lights don't work at all, check the turn signal switch. Brake lights are routed throug the turn signal so that you can use the same bulb for turn signal and brake light. BTW, if you have an air bag, don't attempt to replace or inspect the turn signal switch yourself. It can be very dangerous.
i have conected the black and red wire to the brake and it works (the brake light that is) and i conected the blue and white to the signal lights each wire being left and right signal and it all works. but when i brake all of the light lights up the red bar for the brake and the orage bars left and right when i signal left or right whiles braking the signal works but the other signal light sticks on with the brake light. so if any one as any idears please let me know thanks
Above the brake pedal. If your main brake lights dont work but your third center brake light does, then the brake light switch is not the problem. Its is the turn signal switch.
