Pontiac Problems? Ask a Mechanic for Answers ASAP
hi, do you not have brake lights or are the turn signals not working ?
yeah, that lt blue comes from the brake switch and goes through the fuse box on the left side Ip fuse box then goes to the rear lights and you say you have power on that wire at the brake lights circuit board ?
the lt blue /black wire is for the left turn signal at the rear ,,you may have to take the bulb out and see if the power for the brake lights is getting to the bulb ,in the socket
is there power coming out of the brake switch on the lt blue wire when you put on the brakes ?
battery voltage ?
do the parking lights work ?
if they do and you have turn signals then it won't be a ground problem ,
did you check the bulbs in the third brake light ?
did the mechanic find the issue ?
