Turn signals wont work causing tempture controls to flash

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.

It sounds like there may be an issue with your turn signal relay. The turn signal relay is a small device that helps to control the electrical current flowing to your turn signals. If it's malfunctioning, it may cause your hazards to flash instead of your turn signals when you activate them.
In most vehicles, the turn signal relay is located in the fuse box or under the dashboard. You can consult your vehicle's owner manual to find out the exact location of the turn signal relay in your 2009 Chrysler town and country.
Before you start checking the relay, it's a good idea to make sure that your turn signal bulbs are all working properly. If any of the bulbs are burned out or damaged, this can also cause your turn signals to malfunction.
If your bulbs are all working properly, you can try swapping the turn signal relay with another relay in the fuse box to see if that resolves the issue. If swapping the relay doesn't work, you may need to replace it.
If you're not comfortable working with electrical components, it's recommended to take your vehicle to a qualified mechanic for further diagnosis and repair.

Make sure all the bulbs are working in the turn signal. Some front turn signals will use two or more bulbs per side. If any one of these bulbs are burned out it will cause the turn signal to flash at a fast rate. It also could be a bad control lighting control switch a.k.a. multi-function switch.

check the flasher relays in the fuse box. these are what causes the lights to flash.

Hi, i recommend testing the switch and flasher module. i will post the testing procedures for both devices. replace the device that is faulty.

To test turn signal switches, use a 12-volt test light to probe for voltage into and out of the switch. The ignition switch must be in the RUN position for the circuit to operate. If voltage is present on the input side of the switch but not on the output side, the switch is faulty.

FLASHER TEST PROCEDURE---

• A test light can be used to determine which flasher is used for the turn signals and which is used for the hazard warning light.
• An easier way is to turn on both the directionals and the hazards. This activates both flasher units.
• By removing one of the flashers, the affected circuit no longer flashes.
• Therefore, that flash unit controls that particular circuit.
• If the turn signals fail to operate and the fuse is good, the flasher has probably failed.
• Occasionally, the flasher does not flash as fast as it once did, or it flashes faster. This is also cause for replacement.
• If it flashes too slowly or not at all, check for a burned-out bulb first.

the flasher is located in the Front seating area, driver side, driver side of steering column, mounted in corner behind instrument panel

If the turn signals operate properly in one direction but do not flash in the other, the problem is not in the flasher unit. A burned-out lamp filament will not cause enough current to flow to heat the bimetallic strip sufficiently to cause it to open. Thus the lights do not flash. Locate the faulty bulb and replace it.

turn on the turn signals without turning on any other lights, first left, walk around the car, and see if there is a light that is not functioning, then right, and do the same. If there is a light that is not functioning, replace the bulb.
If all lights work, then its the unit flasher unit itself, and can be baught at a parts store, and is easy enough to replace in the fuse box of most cars.

could be the flasher.
