Dee Hass Posted July 19, 2023 Share Posted July 19, 2023 No brake or turn signal on my rear lights. When I turn my headlights on my rear lights work as well. Just no brake or turn signal. Link to comment Share on other sites More sharing options...
Bloo Posted July 19, 2023 Share Posted July 19, 2023 Check your fuses. Check the bulbs. They have two filaments inside and the filament for brake/turn can be burned out while the one for the tail light is still good. Link to comment Share on other sites More sharing options...
Dee Hass Posted July 20, 2023 Author Share Posted July 20, 2023 Appreciate your quick response. I have recently changed the bulbs thinking that was the issue. I can't find the brake switch to eliminate that as the cause. Recently changed wiring harness in the steering column. New to this vehicle so trying to figure it out slowly.

Bloo Posted July 20, 2023 Share Posted July 20, 2023 Well the brake circuit also goes through the steering column if that's where your turn signal switch is. Look near the master cylinder for a hydraulic brake light switch. I'm not sure it's there and I'm not sure it's hydraulic, but it probably is. Make sure you have voltage on one terminal, and then both terminals when someone steps on the brakes hard. The next place that wiring goes is to the signal switch. Find your flasher. You should have voltage on at least one terminal and probably two. You can probably ignore the middle ("P") terminal for now. The next place this wiring goes is also the signal switch. Do the front turn signals come on? 1 Link to comment Share on other sites More sharing options...
Dee Hass Posted July 20, 2023 Author Share Posted July 20, 2023 Yes front lights work for parking and turn signal. 1 Link to comment Share on other sites More sharing options...

Rusty_OToole Posted July 20, 2023 Share Posted July 20, 2023 I'm told the brake light switch is near the back of the car, just ahead of the rear axle, on the brake line. 1 Link to comment Share on other sites More sharing options...

Dee Hass Posted July 24, 2023 Author Share Posted July 24, 2023 Turns out it was signal switch as Boo mentioned earlier. I tested my lights with a spare one and everything worked except my brake lights. Another question if I can have help, is there an aftermarket bulb socket I can convert to? Existing rear stop/brake sockets wires are getting freyed so looking to update to something newer and easier to install. Thanks 2 Link to comment Share on other sites More sharing options...
Rusty_OToole Posted July 24, 2023 Share Posted July 24, 2023 Bulb sockets are a standard parts store part. It may take a little phenageling to get them to fit your light housings. Brake lights may be a faulty pressure switch, they are known for failing. Or it could be more frayed wiring. Link to comment Share on other sites More sharing options...
