Hello. Check the fuse. It should have been burned. Go to the repair shop to check the repair. I wish you a happy use of the car [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The car's turn signal does not light up and the double flashes may be because the turn switch is broken or the fuse is broken:

1. This is because some cars are separated from the double flash and turning insurance, please check the insurance first, if the insurance is not broken, then there is a problem with the double flash switch;

2. If the lights of the car are not lit, the biggest possibility is that there is a problem with the circuit. Check whether the switch is damaged first, and then check the circuit problem under the condition of ensuring that the switch can be used normally, focusing on checking whether the circuit is short-circuited or open-circuited, resulting in the turn signal and alarm light not lighting;

3. After the problem is determined, see if you can repair it. Of course, poor contact and damage to related equipment are not ruled out. If the cause of the fault cannot be determined, it is recommended to go to the car repair shop for inspection and replacement.

If the vehicle's turn signal only turns on and does not flash, it is possible that the flasher is damaged.

The flasher is connected in series in the turn signal circuit, relying on the regular opening and closing of the internal contacts of the flasher to achieve the purpose of light flashing.

If the internal contacts of the flasher cannot be effectively separated, the turn signal will always be energized, so it will not be able to flash.

Workaround: Replace the flasher.

Try changing the flasher of the steering.

If there is a broken bulb, look at the rear turn bulb.

The turn signal and double flashing are not lit, it is recommended to check the vehicle light switch and wiring harness as soon as possible for short circuit. If necessary, go to the 4S shop for repair as soon as possible.

Turn signal double flashing does not light up solution:

1. Check whether there is electricity at the live wire end of the flash relay. If there is no electricity, check whether there is a disconnection between the line and the power supply.

2. If there is electricity, use a screwdriver to connect the two binding posts of the flash relay, and the turn signal is on, indicating that the flash relay is faulty and should be replaced. If it does not light up, the flash relay should be checked. Open the flash relay cover and check whether the coil and resistor are in good condition.

If the resistor is hot and the contact cannot be closed, the movable contact can be pressed; If the turn signal is on at this time, it means that the relay is faulty. Adjustments should be made when the contact gap is too large. If the turn signal is still not lit when the contact is closed when the active contact is pressed, the contact can be shorted with a screwdriver, and if the light is on at this time, it means that the contact is oxidized.

3. When the two binding posts of the flash relay are shorted with a screwdriver, and the turn signal does not light up, it may be that the steering switch is faulty. During the inspection, you can use a screwdriver to connect the steering switch live wire and the left and right light wire binding posts respectively. If the light is on, it means that the steering switch is faulty and should be removed for maintenance or replacement.

2.Measure the voltage on the hazard warning light switch terminal 8 with a voltmeter. Is the battery voltage on the connector terminal 8 equal to the specified value?

11-14 volts 3Remove and disconnect the hazard warning light switch for testing. 4.

Turn on the hazard warning light switch. 5.Test the resistance between terminal 7 and terminal 8 with an ohmmeter.

6.When the hazard warning light switch is removed and disconnected, turn on the hazard warning light switch. 7.

Check with an ohmmeter whether there is conduction between the terminal and 9. 8. Repair the open circuit fault between the hazard warning light, switch connector terminal 8 and fuse F14. 9. Replace the faulty hazard warning light switch.

In this case, it should be the problem caused by your steering relay, or the insurance damage of the turn signal, you can find, find an auto repair shop to repair it, change an insurance, or give the relay a try.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Go to the car and remove the flasher. The position of the flasher is in,The lower part of the speaker head (you can find it by listening to the sound),You need to remove the head first,Then disassemble the air conditioning control panel,After finding the flasher,Remove the bracket,Unplug the wiring harness,Then remove the flasher,Buy a relay of the same size,Then remove another relay as well,Cut off the extra feet of the new relay you bought,Install it。

The turn signal and double flashing lights are not on, there must be a problem with the line. Need to go to the repair shop to have a look.

There is a problem with the circuit, it is recommended to go to the car repair to check, these two are flashing, and there is a problem with the relay that is not good for the flashing.

There are two reasons for this situation, the first is that the internal contacts of the turn signal switch are short-circuited and both sides are energized at the same time, and the other is that the flash relay contacts are ablated by UMC and both sides are energized at the same time. Hello, this should be the reason for the short circuit of the line, check the line There are two reasons why the left turn signal is double flashing: 1. The double flash relay is damaged.

2. The contact point of the lever is not real. The rules for using lights are: 1. When the street lights are turned on at night, or when driving in low visibility conditions such as fog, rain, snow, dust, hail, etc., the headlights, marker lights and rear position lights should be turned on.

2. Turn signals should be turned on 100 to 50 meters in advance when turning, changing lanes, overtaking, making a U-turn, and pulling over. 3. When a motor vehicle passes through an intersection controlled by a traffic signal and turns left, turn on the turn signal, and turn on the low beam when driving at night. 4. When the rear car and the front car driving in the same direction are driving in close proximity, high beams shall not be used.

5. On roads where there is no central isolation facility or no center line, low beams should be used at night when meeting vehicles in the opposite direction at a distance of 150 meters from oncoming vehicles, and low beams should be used when meeting vehicles on narrow roads, narrow bridges and non-motorized vehicles. 6. When a motor vehicle passes through a sharp bend, slope, arch bridge, pedestrian crossing or an intersection without traffic signal control at night, it shall alternately use high and low beam lights. @2019

There are two possibilities, one is that your lamp is broken, which is less likely, and the other is that your circuit control system is faulty, and it is recommended to repair it.

This fault should be caused by a fault in your car's wiring system. If we are not familiar with the line system, it is not easy to find the fault point. It is best to find a professional staff in a 4S shop to solve this problem. If we don't understand, it can make the problem worse.

Go to the 4S store to test it, otherwise it is very unsafe.

It is recommended to go to the place where the car is repaired.

There is a problem with the signal light circuit.

Because your light is broken, it's best to fix it.

Find a repair point to see if it is a poor contact.

Headlight bulbs also need to be replaced regularly. Generally speaking, every 50,000 kilometers or about 2 years, the brightness of the headlight bulb will be weakened, at this time it is best to go to the 4S store for a test, if there is indeed a lack of brightness, then it is recommended to replace the bulb, it is recommended to replace the left and right sides at the same time, so as to avoid the situation that the brightness on both sides is not the same. I just didn't replace the bulb in time after the brightness of the bulb dimmed, which caused the time to be wasted during the annual inspection.

1. Check the tightness of the headlamp.

If there is water vapor intrusion in the headlamp, it will reduce the service life of the bulb, so it is necessary to check the tightness of the headlamp. If the sealing ring between the light distribution lens and the reflector is found to be damaged, it should be replaced in time.

2. Clean the mirror.

The reflector of a semi-enclosed headlamp becomes black and the luminosity decreases and should be replaced. If there is only dust on the reflector, it can be blown with compressed air instead of replacing it. For the mirror that cannot be blown clean, if the mirror coating material is chrome-plated, due to the high hardness, you can use deer skin dipped in absolute ethanol (content of more than 95%) from the inside of the mirror to the outside in a spiral shape and gently wipe it carefully.

If the mirror is silver-plated and aluminum-plated, due to its poor hardness, it can only be cleaned with clean cotton dipped in hot water, and must not be wiped to avoid damaging the mirror plating.

Some mirrors are pre-coated with a thin and transparent protective film on the surface of the dough, so be careful not to damage it when cleaning. If the mirror is frequently dirty, it means that the sealing rubber ring is damaged and must be replaced. After wiping or cleaning the mirror, be sure to dry it before putting it back on, and pay attention to whether the installation position is correct.

3. Clean the bulb.

Halogen bulbs can be scrubbed with absorbent cotton soaked in ethanol (90%). Be careful not to scrub the lights when the lights have just gone out and the bulbs are still hot. After cleaning, it should be dried instead of wiped dry, and do not touch the bulb with your hands or rags, and turn it on immediately, otherwise it will lose its luster or even cannot be restored.

It should be that the fuse of the turn signal is broken.

Please go to the after-sales service.

Wishing you health and happiness.
