What year is it? I have an 86, it does the same thing. I havent been able to figure it out either. With a volt meter it reads 12 volts at the terminals, but it wont light the bulbs.

Might have an issue between the switch and the light itself.

I have the same problem except it only works when the car is off. I noticed it when me and my girlfriend were sitting in it having a "smoke" and it didn't turn on. Then I turned the car off and it worked just fine. I just use my visor-mirror light

According to the volt meter, all the switches work properly. It reads 12v at both when the buttons are pressed, and when the door is open. I think it is immediatley burning out the lights. Or the polarity is backwards, But i dont think it would matter with those kind of bulbs.

Polarity is not an issue. Mine had the same troubles. Its a supra thing.

The trouble is in the light assy., not the door switches.

I found the ground circuit does not make a good contact, for one thing.

I also had to screw with it all for 3 hours. I had to re-solder the wires to the terminals 3-4 times to make a goog connection. It was a real nightmare project, but they've been working now for 3 years.

yeah I'm too lay to screw with my lights for that long. i just use the visor mirror to pack my bowls......

well some bulbs for cars are meant to be 6v but they have resistors and diodes that only make them work with a certain polarity, and so they can run on 12 volts. Same with LEDs, becuase they are diodes. But i need my dome light to work, because i deliver pizza. lol. Its very helpful
