92 HAS ALL 3 BRAKELIGHTS OUT.

1992 Honda Accord • 278 miles

Brake switch has been replaced, right side brake senor replaced, new wire ran from brake switch to backside(trunk) of main harness. Don't have a voltmeter. Trying to figure it out without purchasing any tools, I know it will be a challenge. Any ideas?

You need something to check for power. Even a home made test light. If you ran a new wire to the main harness and they still don't work, there has to be a problem before the switch. You need to check for power. Make sure fuses are good too. Once you get a light or volt meter, check for power to the switch and out.

It is a new brake switch. I think the old one still worked. The lights do work after I put in a new fuse, but as soon as I drive around for a very short distance then they go out again. I have tried wiggling all of the cables in the trunk with the brake lights on and nothing happens. They work. Until I drive to work the next morning.

There has to be a short between the new wiring you installed and the lights. Also, check the light sockets. I have seen them break down inside and short.

The problem is the same even before the new wire was put in. I have one light socket that was corrided inside, but was still working. I disconnected the pig tale (the corrudied wire) and the lights still go out.

If it is the same with the new wire, the problem has to be between the two. You bypassed the original wire, so that can't be the problem.

I will look at the wiring again in the trunk after the main harness. I think I will close the trunk lid this time and from the inside start moving wires around until I see the lights go out. It they go out then maybe that will give a direction or side to pay more attention to. I will let you know what I find.

Sounds good. Let me know, and have a great Thanksgiving!

Nothing happened. I replaced the fuse, set brakeslights on, got into the trunk and moved the wires around the bulbs, sensor, main harness, 3rd light wires. Nothing went out. I even jumped up and down on the rear bumper and nothing went out.
