U NEED A VOLT METER OR TEST LIGHT TO CK. FOR VOLTAGE TO THE BULB CONNECTOR. IF U HAVE NO POWER. CHECK YOUR VOLTAGES AT THE HEAD LIGHT SWITCH THEN COMEBACK

I am getting to the voltage testing, but I did discover that the headlights will work if the car is not started or key not switched ON. Once the key is turned, only the high--beams will work.

The brake lights-Not the bulbs, not the bulb clip assembly thing, and the green wire(marked high beam) has no power under any condition. The ground and low beam wiring is fine. Also, the third brake light works.

I will check the brake switch first chance. Moving the steering column position does not affect the lights in any noticeable way.

Thanks!

So here is what I know.

All related fuses (not sure about any relays) are good.
The Bulb and socket test good
The tail harness gnd and driving (tail) light good (the wire for brights DEAD)
The Brake switch is functioning and testing good
The voltage from the male (battery) side into the brake switch is good.

Apparently, the wiring between the brake switch to the tail light is corrupted. Anything common I could look for along the line, like some kind of in-line fuse or under vehicle exposure?

Thanks!

oh yeah, if I did not mention this, I just discovered that the headlights will work as long as the car is off. If the key is turned they won't work so we are driving with the brights on.

Thanks for your time and help. Can you offer any advice on where to look for the ground problem? I will check the fuse box and connections closer, but are there any places that commonly short or break from some exposure?
Thanks!

I'm sorry, but I thought I had covered that. No, there is no power getting the socket. The socket tested fine on both sides and the bulbs are good.

The brake switch is good (12.2V from the battery side) so the wire dies somewhere in between.

It may be important to know the lights in the panel go dim when the headlights or parking lights are turned on. The auto-lock feature for the doors is not working now and the headlights will come on as long as the key is not turned in the ignition. The HUD is not accurately showing fuel levels or economy.

Could this be from water coming in through the sunroof?
