Brake light and right turn signal come on at same time

That happened in my 1999 Buicke Century. Replaced the bulb 4 times kept burning out all within a week. Finally replaced the blinker socket and no more issues.

The tail light is usually a bulb with lower wattage, so it won't glow as brightly as the brake and turn lights.. There should be one or two other bulbs in either of the two tail assy's. The turn signal can use the same bulb as the brake light. If so, it's up to the flasher assy to direct the lights to both come on, and/or for one to flash if the brake and turn signal is on, e.g.. There could also be a backup light.

So if the brake and turn lights don't operate, look to the fuses, and flasher assy. for possible replacement.

The ground wiring on newer vehicles is a little complicated. Older cars, the ground would have been to the body around the tail-lights, but these have a ground wire in the harness and is connected to the turn-signal switch, and other sources. I don't think you have a ground problem. Does the fuse blow as soon as you press it into the fuse-block, or when you step on the brake? I believe you have a dead short somewhere, possibly a pinched turn-signal wire close to the tail-light assembly. Brake lights work through the turn-signal wires from the turn-signal switch on the steering column. That's how you can have one side blinking for turn while the other side stays on for brake. I'm kind of shooting in the dark here because I don't know what all you've done. If you replaced the turn-signal switch in the steering column, you may have pinched a wire or something there. Another thing, if the fuse doesn't blow as soon as you press it in, will both turn-signals work as long as you don't press on the brake? If you can provide a little more information, I might be able to help you more. One last thing....Have you replaced tail-light/turn-signal bulbs? If so, be sure you used the right bulb. You should only have two bulbs, one for back-up lights and one 1157-type combination for tail-lights and turn-signals. I have seen people use a single contact (1056) bulb in place of a 1157, which creates a short from brake/turn-signal back into the tail-light circuit. I do have a 1994 Dodge Dakota.

Turn signal tail lights and BRAKE LIGHTS NOT WORKING

It can be faulty brake light switch causing the problem or its blown brake light bulb. First check and confirm brake light lamp is working and that's not the case.

For turn signal not working it can be faulty turn signal switch or its issue with wiring:----

These will help.

Thanks.

Fast flashing dash signals mean there is a bulb issue-DEFINATELY!

The brake light side of the bulbs is powered by the brake switch and travels thru the turn signal switch.
If the third brake light works, I would guess the problem is in the turn signal switch.

If the brake and turn signal are on the same bulb than you can Orin straight wiring. If the brake and turn signal are on different bulbs than you'll need a wiring harness with a converter box. I'm pretty sure the wrangler has the brake and turn signal on the Same bulb so let's start with basic trailer wiring. The green wire on the trailer harness is for the right side turn and brake for the trailer. This wire should be attached to the wire on the vehicle that supplies power to the right turn signal/ brake light. The yellow wire is the left turn signal, brake light on the trailer and should be attached to the wire on the vehicle that supplies power to the left turn signal /brake light. The brown wire is the tail lights on the trailer and should be attached to either the left or right side wire on the vehicle that supplies power to the tail lights. The white wire is grounD and it is vitally important that this wire be attached to the vehicle in a manor that supplies a good ground. Failure to suppy a good ground will result in all kinds of funky problems with the trailerer lighting such as all the lights linking when the tail lights and turn signals are on at the same time. If you have any specific questions I will be more than happy to try and help. Good luck.

Sounds like you need to replace the drivers brake/tail light.

sounds like brake shift interlock is not sensing brake pedal apply so it can activate solenoid to allow shft from park.
Check bulb socket and replace if bulb ok

There should be at least 2 bulbs in the light assembly. One light is the light that is on when you turn on your headlights with out the brake pressed, the other light only lights up while you press on the brake. Make sure you are replacing the correct bulb. You may have been replacing the bulb that stays on. Your lights may be set up to turn off the light that stays on when the headlights are on while pressing the brakes.
