Brake Lights Won't Work

[anditfeelsgold]

I own a 1990 240sx hatchback.

Today, after I redid the rubber around my tail lights to stop the flooding in my trunk, I noticed the brake lights no long worked after I re-installed them.

The running lights work, the reverse lights work, and the rear blinkers, but the brake lights don't come on when I hit the brakes.

Any suggestions?

I had the same issue and it turned out to be slightly loose screws. Might want to check the screws.

Which screws?

I had to take them all out when I replaced the tail lights. Why didn't they work with loose screws?

The same screws that your rear lights are working off of. When mine wasnt working I noticed a bit of a spark where the screw was loose. I tighted them up and it worked fine. Just an idea. It could be a number of things. Do you have the center rear brake light also? Is that working?

The grounding wire?

Thats on fine if it is what you're talking about.

Yeah, I've got the center light too, but it doesn't light up when i hit the brakes.

All the lights work fine, the brake lights come on dim when i turn on the headlights like they're supposed to, but when I hit the brakes they don't get brighter.

I've messed with the brake switch on the brake pedal just to see if it was malfunctioning, and it works fine.

I've noticed there are 3 wires running to each brakelight, one black, one red with blue, and one red with green, so i'm assuming one of them controls the brake lights to get brighter, and light the other filament inside the bulb.

I'm stuck on ideas for the moment.

They worked fine before i took them out, and all of the fuses look good.

If I short circuit the switch at the brake pedal, I can get the brake lights to turn on.

Is there a problem with a fuse or relay then?

im bringing this back to life cause i have the same problem. now i have a few other electrical issues, and i wonder if there related. last post started the way im thinkin, see i also have a headlight issue aswell, which i think is a relay or something, and my clock resets everytime i open and close my door. i really think that its in the door, i know there are some relays and timers in the door, so i have no idea, but i need some help.....

i'm having a issue with my brake lights also and my door light is on too. it use to come on when i pressed the brakes and the clock would reset too.
