ok, i need your help guys.. car is 1991 teggie, my brake lights wont turn on but the back lights and signal lights work. i checked all the fuses and its all good! i just cant firgure it out! bulbs are fine. what can be other possible causes of this? thanks guys

 

make sure fuses are all good...by using a test light or something...not by just looking...cause they could break a funny way, and you wont be able to see it...

i went without brake lights for like 2 years, and one day i got fed up, and replaced the "good" fuse and voila...

 

like esguerra said, sometimes fuses look good but are not, but if after you check and swapped out the fuses , check the brake light switch at he brake pedal

use a circuit tester and check for power when the pedal is pressed which will send signal to the relay and turn on the brake lights

if that's fine, use the tester and check power at the harness or bulb socket at the light assembly... still nothing? u got a broke wire or ground problem

good luck .....

 

how about your brake light switch which is mounted towards the top of the brake pedal it probably needs replacing

 

alright tanks guys, solved! well the horn, the brake lights and the cruise control is wired all together in g2's i found out.. so i checked the wires and i had a bad ground for all of them..
