Question about 1989 Ford Thunderbird

1 Answer

No Brake Lights

I have a 1989 T-Bird SC w/ABS. I have no brake lights. I have changed the fuse, checked the bulbs, and replaced the switch under the pedal. Still no brake lights. The running lights and turn signals work fine. I tried jumping the wires to the brake switch (with the key on) and still no lights. There appears to be no power to the brake light switch. Is this a relay problem? If so, where is it? Any suggestions are very appreciated.

I have the same problem I suspect the circuiut that involves the criuse control as cruise will not disengage on tapping of the brakes and thence the brake lites are out again.

I have no brake lights at all not even the high mount light. I changed the bulbs and I checked the fuses.

This model T-bird has a brake light switch that commonly wears out...also, how it attaches is suspect to failure...the bracket and the switch are attached by an adjustable nut, and could just have slipped.

I have had this problem before, and had to jimmy-rig mine with a bit of flexible wire to keep it in place.

The brake lights do not want to work. i have changed the brake switch under the dash and the bulbs on the tail lights.still nothing. i also, changed fuses.

does the high mounted brake light work? the brake switch has 2 contacts one for the high mount (LT BLUE/BLACK) and one for the tail brake lights. The tail/brake light wire is LIGHT BLUE. the main connector between the brake light switch and the tail lights is C208 which is located behind the rear seat, left side. So if there is power coming out of the brake switch OK and no power at the tail lights, check that connector. Hope this helps.

1989 Toyota Camry. No brake lights.

It could be the relay, which is a yellow box located under the carpeting in the trunk on the left side. It is a problem common to your model. Also, check the brake switch's (behind the brake pedal) functionality (12V present with key at ACC or ON and continuity between wires when button engaged).

i hope this helps
