So I've hit a little snag with prepping my car for inspection. I just completed a brake job (rotors, pads) and realized that the Brake Lamp light is coming on in my dash. I've confirmed that I don't have brake lights (all 3), don't have any horn and the cruise control light doesn't work. I checked the under the hood fuse relay and switched in a good/spare #30 20A fuse and everything still does not work. The fuse does NOT short out and all other systems from the relay box appear to be functioning properly.

At this point I'm looking for what my next steps should be or possibly where the issue may be? I'm doing my best in reading over the repair manual's circuit charts. (attached below) Because all three systems are out, it seems to me that it eliminates a break light switch issue? Trying to follow a wire from the UH fuse relay box seems almost impossible.

To check electrical current the only tool I have is a non-contact voltage tester pen, although I could use some direction as well as to how to use this in my situation.

Any help or direction for next steps is appreciated.

Thanks

Did you by chance replace the tail light lens assemblies? If you did, you have to make sure you remove and swap the relay unit in the left lens assmebly. That will cause you brakes not to work. Not sure if it will affect the others though.

 

Did you by chance find some mysterious rubber pieces laying on the floorboard on the driverside? If so then it's an easy $3.00 fix. There is a rubber button towards the top of the brake pedal (well there should be) if you happen to see a hole in the pedal then that's your problem.

 

Did the brake light come on and the brake lights were out before you did the brake job? Normally, if the brake lights are out, it is the brake switch that failed. I would check the brake switch to make sure it closes the circuit when you step on it. You will have to take it out to test it for continuity when you press the switch and replace it if it does not close. The electrical diagram is wrong. If the horn is directly connect to the battery as depicted, it would go off all the time. There is a control circuit to tie the horn to your steering wheel horn switch that is not on the diagram.

 

Normally when the brake switch goes bad the brake lights stay on.

 

I had checked the brake light switch and that functioned normally. Ironically, both brake bulbs were blown at the same time so when i replaced the two side lights the circuit was complete and worked. I figured that even if the bulb was out the ciruit would have still worked, I guess I was wrong. Problem Solved.
