| Help, I'm a woman who owns a 69 ghia and does most of the work on the ghia. the problem : no brake lights. I do have tail lights, and signals and the brake switch is working. Checked the fuse and the fusebox. I do not know what to check next. Could any one point me in the right direction . thanks. |

| When you say you know the brake switch is working, it's because you've probed the circuit with a test light, right? |

| Believe it or not, you brake light switches, on the MC are electro-mechanical. Try tapping them lightly. If they then work, they need replacing. |

| Have you tried playing with the bulbs? On my ghia, most of the lights dont work in the factory 'lock' position. Play around with it and see if the advice above doesn't help. |

If you have a 69, it should have the red brake light switch on the dash, correct? It is a brake light test switch to check the circuit at the master cylinder for power. That's all it does. Press that button in and if it illuminates, you have power going to the brake light switches on the master cylinder. There are two seperate brake light switches on the master cylinder. If the dash brake light switch does not illuminate you have an open circuit. Or the lamp in the dash switch for testing is burnt out. The best way to check for power is too actually check it at the brake light switches on the master cylinder. You need a VOM or something that can detect 12 VDC. Make sure the ignition is on when you perform this test. Ground one side of the meter lead and check for voltage on one of the terminals on the brake light switches. They are in series so it doesn't matter which one that you check. But you want the 12 VDC side. The opposite side of the terminal goes to the brake lights when you step on the brake pedal. If someone can help you have them step on the brake pedal and check the other terminal (brake light circuit) for voltage. If no power your switches are bad. Check for corrosion at the terminals on the brake light switches, and brake light housing and loose connections. Also what hunter_tromboneman suggested. Most of the time is is just dirty terminals. Check all terminations for the brake light circuit. I use a color code wiring diagram.
Good luck!
Let me know, Rick |
