Replaced brake switch,new brake-light bulbs, fuse ok, still get no brake lights, and turn signals in rear not working....what can i do ?

If both the brake lights and rear turn signals are not functioning in your 2008 Dodge Charger, there are several possible causes to consider. Here are some common issues that could lead to this problem:
1. Blown fuses: Check the fuse box for any blown fuses related to the brake lights and turn signals. A blown fuse can interrupt the circuit and prevent the lights from working. Refer to your vehicle's manual to locate the specific fuse for these functions and replace it if necessary.
2. Faulty bulbs: Inspect the bulbs in the brake lights and turn signals to see if they are burnt out or damaged. If a bulb is not working, it should be replaced. It's possible that multiple bulbs have failed simultaneously, leading to both the brake lights and turn signals not functioning.
3. Wiring issues: Check the wiring connections and harnesses for any signs of damage, loose connections, or corrosion. Faulty wiring can disrupt the electrical flow and prevent the lights from operating. Repair or replace any damaged wiring as needed.
4. Malfunctioning brake light switch: The brake light switch, located near the brake pedal, activates the brake lights when the pedal is pressed. If the switch is faulty or misaligned, it can cause the brake lights to not work. Consider having the brake light switch inspected and replaced if necessary.
5. Faulty turn signal relay: The turn signal relay controls the flashing of the turn signals. If the relay is defective, it can prevent the rear turn signals from operating. Consider replacing the turn signal relay if other potential causes have been ruled out.
If troubleshooting these common issues does not resolve the problem, it is recommended to consult a professional mechanic or authorized Dodge service center for a more accurate diagnosis and repair. They will have the expertise and necessary tools to pinpoint and fix the specific issue with your 2008 Dodge Charger's brake lights and rear turn signals.

If the other brake and turn lights are working the brake light and flasher units are ok . With a test light check at the bulb holder terminal and bulb holder body, test light should glow ,if not check from terminal to a metal part of panel away from the light body . If test light now glows the brake light body has a bad earth if the test still not glowing the power cable to the light is broken.

The third or High Mounted Brake Light runs straight off the brake light switch on the brake pedal arm. You say you tested the "brake unit"? I assume you mean the third brake light assembly, and if you get power there when someone steps on the brake pedal, then the bulbs are bad.

The power flow for the brake lights goes like this: Fuse ->Brake switch -> Turn signal switch -> Rear lights. The only difference is, if you have a 3rd brake light in your rear window, that gets its power directly from the brake switch. It does not go thru the signal switch first. So, if you are having a brake light problem, and your fuses are good, check the 3rd light in the rear window, if it lights up (assuming the bulbs are good, no one ever changes them), then the problem is most likely in the turn signal switch, hope this helps!

Hi, the likely problem is the turn signal switch. The signals and brake lights use different fuses. You can get an owners manual here:

A new switch is about $40, and it isn't too hard to replace. Make sure you get one that has the same controls as yours does. To replace the switch, remove the covers from the steering column, disconnect the switch and unscrew it from the column.

Please let me know if you have questions, and thanks for using FixYa.

Replace the turn signal switch. All of these lights run threw it.

u have a short loose ground or power wire check all bulb sockets ur head light switch can be bad also

Hello,
The rear turn signals are wired through the Multifunction switch also called the turn signal switch. The Hazard switch is in that switch also and thats the circuitry the brake lights go through. You need to confirm voltage at the White wire off of the brake light switch and if its ok you have a bad multifunction switch.

I hope this helps.

Are the rear bulbs OK?
Is the ground good at the rear?are the sockets good?
Are there tail lights and a license plate light?then the ground is OK.
All the things that you say do not work go through the signal light switch....it may need replacing.
First make sure the bulbs and fuses are OK and power is getting to the signal light switch and to the brake light switch.
Nice car!

check fuse number 7 in Engine Compartment Fuse Box , if its ok you need change turn signal switch
