As many of you know that I am working on Jays 95 SC. While I have it, he also wants me to look at a few things to try and figure out. One of his problems is the rear brake lights will not come on. His running lights work, turn signals, tag, and reverse, but NO brake lights. I have checked the bulbs, and ALL the fuses. Inspected the wiring, and then rechecked the fuses yet again. They are all good. I looked at his brake sensor on his pedal, and it is indeed there and not broke. He has an aftermarket alarm installed and it is a Python with remote start. He also had an auto car and now converted to a V160 and had Dr. Tweak do the harness. His cruise control is completely removed, just the plug hanging. I also have his radio, center console, climate control, and the trim under the cluster out. He also has a Greddy turbo timer and Greddy boost controller installed. I didn't think this would make a difference, or would it? This has got me stumped. I thought for sure it was the brake sensor on the pedal, but it aint, or is it maybe bad? One post stated there is a sensor under the driver side dash, color blue, does this control the brake lights?????

I searched and all the links to the same problem, all the threads are dead, and only a few replies. I need these working before he picks it up.

Any insight on this?

 

Did he replaced the tailights to a newer tailights?

There is a tailight ecu right by the antenna motor on the driver side quater , it's a black box make sure it plugged in, or swap the box with yours.

Will try that when it stops raining. Thanks Quick

He has the original taillights.

 

I did see a small thin 2 prong wire under the dash for the alarm, but didnt see where it went. All the prongs on the alarm brain are full. I am thinking it went to something in the dash that I removed from Jays car, that wasnt needed. I will look more into this tomorrow.

 

come on guys, the tails work and the brakes light up when u arm the alarm. but no brake lights when pressed......

 

Swap the brake switch to see..

 

power goes to the brake light switch
then power goes to that box in the trunk (ive had that break before)
then power lights up the bulbs

use a test light.

 

It was the brake sensor on the pedal. Worked great. Life is good now. Thanks for all the replies.
