The car gauges don t show up, and the doors won t open

Hello! This is when the car battery runs out of power, and you take the mechanical key to open the door. Call for help.

Just take the power and then go to the repair shop to check if there is any problem with the battery. This can be checked with an instrument. If there is no problem with the battery, it is necessary to measure whether there is a leakage phenomenon [If there is a problem with the car, ask the car master.

It is the two-stage poor contact of the battery, there are positive and negative poles on the battery, there are wire links respectively, the connection is easy to oxidize and cause poor contact, the method is also very simple, use boiling water to scald both poles, of course, if you use sandpaper to polish is a regular practice, but it is time-consuming and laborious, this original method is simple and effective, and then use a screwdriver to lock the screws at the joint, it is best to smear it with butter, and it is not easy to oxidize in the future.

Ignition system faults can be divided into two situations according to their position in the ignition system: low-voltage circuit faults and high-voltage circuit faults.

1) Common faults in low-voltage circuits: insufficient battery storage; Poor or deranged wire connections; Poor battery tie-up; Damage to the distributor or Hall sensor; Damaged ignition switch or poor wiring; The transistor ignition control unit is damaged or poorly wired. Most of the diagnostic methods for low-voltage circuit faults use ammeter or voltmeter to check the fault line by line to eliminate the fault point.

2) Common faults of high-voltage circuits: high-voltage lines fall off or leakage; Breakage and breakdown of distributor cover; Ablation, rupture, breakdown of distributor fire head; The spark plug electrode gap is too large or too small; Excessive carbon deposits in the spark plug; damage to the spark plug insulator; The ignition coil is damaged or the wiring is falling off. Most of the faults of high-voltage circuits adopt the high-voltage fire test method, that is, the high-voltage line in the center of the distributor or the high-voltage line of a cylinder is unplugged, and the wire head is placed at a distance of 3-6mm from the cylinder block, and the engine is started to test the fire, as shown in Figure 2.

If there is a spark and the spark is strong, it means that the ignition system is working properly.

The door switch is broken, the door switch is a normally open electric shock, the door is opened and closed when the door is opened, and the instrument panel shows the door open status.

You can also check the handlebar, and use the wire short to connect the positive pole of the handlebar and the signal line (to put it bluntly, let the handlebar be short-circuited). Solution: If the car rotates and proves that the handle is broken, and it needs to be replaced or repaired urgently, turn on the power and twist the handle to measure the positive wire and signal line with a universal meter.

(1) "Vehicle" means motor vehicle and non-motor vehicle.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

It may be that the door switch is broken, the door switch is a normally open electric shock, the door is opened and closed when the door is opened, and the instrument panel shows the door open status.

Hello, the door dashboard behind the main driver and the main driver is not displayed, what is the problem.

It is the reason why the door of the individual is not closed properly, and there is a door sign showing a yellow light, in addition to the door and the trunk is not closed.

When the door is not fully closed, the instrument cluster lights up to indicate that the driver has not closed the door, and the indicator light turns off when the door is closed. The engine cover and trunk door are not closed, which is also displayed on the instrument cluster. The engine cover and trunk door are not closed, which is also displayed on the instrument cluster.

Commonly used automotive instrument indicators.

1. Fuel indicator.

When the light is on, it means that the fuel is about to run out, and generally the vehicle can still travel about 30-50 kilometers from the light to the time the fuel is exhausted.

2. Water temperature indicator.

When the engine coolant temperature is too high, stop the engine immediately and turn off the engine, and then continue driving after cooling to a normal temperature.

When the door is not fully closed, the instrument panel will light up to indicate that the driver has not closed the door, and the indicator will turn off when the door is closed. The engine cover and trunk door are not closed, which is also displayed on the instrument cluster. The engine cover and trunk door are not closed, which is also displayed on the instrument cluster.

The dashboard shows that the doors are not closed, check the corresponding four doors, which one is not closed tightly, and close it.

Hello, if the door of the vehicle is closed but the dashboard shows that the door is not closed, first check whether the door clearance is normal or whether the door switch is faulty, if there is no problem, check whether the wiring harness is short-circuited.

If the door is closed and the dashboard shows that the door is not closed, you need to check whether there is a problem with the lock block.

Hello! In this case, it is mainly caused by the damage of the door light switch, this is recommended to go to the repair shop to check the door light switch and check the wiring at the same time.

The dashboard shows that the door is not closed, go to the repair shop to check that the door limiter is broken, and replace the limiter.

Hello, in this case, there is a car door that is not closed properly, it is recommended to check next to each other to see if it has been closed.

Hello, this situation may be caused by the door is not closed properly, it is recommended to try to close the door again.

In this case, it is mainly a problem with the door side light switch, and more importantly, it is recommended that you measure the door side light switch for each door to see if there is a broken wire or a place where the wiring harness is lapped.

Hello, check the door lock or limiter, if it still doesn't work, it should be caused by the wiring harness on the door, it is recommended to check it.

The reasons that cause the door to be opened inside and outside are: 1. The child lock is in the open state, 2. The door lock block cable fails, 3. The door hinge and lock post are deformed, 4. The door limiter fails.

1. The child lock is on.

The rear door of the general vehicle has a child lock, located on the side of the door with a child's sign, if you accidentally open it and close the door directly, then the door can not be opened, so when closing the door, you must remember to see if the child lock is closed, if it can't be opened, we need to take out a word to change the cone, and screw the child lock to the closed state, on it.

2. The door lock block cable fails.

If the cable fails, it will directly affect the lock block can not be opened, and after this kind of problem, we can only change the door lock block to pull the wire, so as to make the door reopen.

3. The door hinge and lock post are deformed.

When the door is subjected to a certain external force, it may lead to the deformation of the door hinge and the lock post, which is also one of the reasons why the door can not be opened, after this problem occurs, only the door and the door hinge are disassembled together, and then replaced with a new hinge and lock post, so that the door can be opened and closed normally.

4. The door limiter is out of order.

The failure of the limiter is also one of the reasons why the door cannot be opened, after this problem, it is very laborious to open the door, or it cannot be opened at all, and the solution is to replace it with a new door limiter.

1. The door lock block cable fails, and the door lock block is pulled with the line; 2. The central lock of the door is open, and then try to open the door after the central lock button is unlocked; 3. The remote control key cannot open the door, and the mechanical key can be used temporarily to open the door. 4. The child lock is in the open state, and the child lock is screwed to the closed state before opening the door.

Question: How do I screw it to close and then open it?

The answer is that the door lock mechanism itself is faulty: the probability of the door lock itself failing is very low, and most of them appear on the body of the car that is relatively old. No matter how high-end your car is, its working principle may not be able to be said by ordinary people, but the structure of its door lock is relatively simple, basically composed of lock cylinder, lock block, central control motor, and control mechanism.

In most cases, they can be solved by replacing the central control motor or by lubricating the lock block and control mechanism.

You can't open the question like this.

You can try to add some lubricating oil to the lock cylinder to see if it can be opened, if it still can't be opened, you need to replace the lock cylinder.

Several situations and solutions for the door can not be opened: 1. The door lock block cable fails, and the door lock block is pulled with the line; 2. The central lock of the door is open, and then try to open the door after the central lock button is unlocked; 3. The remote control key cannot open the door, and the mechanical key can be used temporarily to open the door. 4. The child lock is in the open state, and the child lock is screwed to the closed state before opening the door.

1. The cable of the door lock block is out of order. If you can't open the door from the inside of the car, you can basically determine that the lock block can't be opened due to the failure of the cable, and the door will not open at the same time.

2. The central lock of the door is open. When the door can't be opened, you can use the car key to unlock it first, and then lock it, repeat twice, and then find the central lock button on the left front door trim of the main cab, press the unlock button, so try to see if you can open the door.

3. The remote control key can't open the door. You need to check whether the remote control has power and replace the battery; If it's not a battery problem, try to see if other buttons on the remote control can work, such as opening the trunk; If all the other keys work, it's a problem with the door control part, and in the case the remote key doesn't work, you can temporarily use the mechanical key to open the door.

4. The child lock is on. The rear door of the general vehicle has a child lock, if the door is closed directly in the open state, then the door can not be opened, you need to take out a word change cone, and screw the child lock to the closed state, so that it can be opened.

What should I do if the car door sometimes opens and sometimes does not open?

First check whether the child lock in the car is opened, resulting in the inability to open the door, and then use the spare remote control key to see if the remote control fails, if the remote control key can not open the door, you can also try to unscrew it with a mechanical key. If the above reasons are ruled out, it is basically the fault of the door lock mechanism itself, and you need to find a lock company.

1.In winter, it is cold and the car door cannot be opened.

In the north, winter temperatures are very low, mostly below freezing. After we wash the car, some of the remaining water will accumulate in the door handles, locks, door frame gaps, etc., and after a night of severe cold, the water turns into ice, which freezes the car door firmly and cannot be opened in the morning.

In this case, you should not use the violent method of "pulling hard" to open the door, as it is likely to damage the paint and sealing strip, and it is possible to break the door handle.

When the door is frozen, the most effective solution is to pour warm water over the frozen door to let the frozen ice melt as soon as possible. Or just wait until noon, when the sun is full and the temperature rises, you can open the door.

It is recommended to pay attention to the timing when washing the car, it is best to wash the car when the sun is full at noon, and carefully wipe the place with water, so that you can also leave time to dry, and easily avoid the problem of the car door freezing.

2.The rear passenger gets out of the car and can't open the door.

The passenger sitting in the back seat could not open the door when he needed to get out of the car, so he had no choice but to let the passenger in the front seat get out of the car and open the door from the outside. In fact, it is not a fault that causes this to happen, and the child lock is the "culprit".

A child lock is a protective tool to prevent children from inadvertently opening the door in the car. This function is usually located on the two rear doors. However, most drivers rarely use it, and even many novice drivers don't know that their cars have this function.

When the child lock was activated, I even thought that the door was malfunctioning.

The solution is simple, just turn off the child lock function. But if you have small children, it's a good idea to turn on this feature, don't bother, open the window and reach out of the car to open the door. Although, it's worth it for the safety of your child.

3.The remote control is out of order.

Each car is equipped with two remote control keys when it leaves the factory, and if one of the keys cannot open the door, you can try it with a spare remote control key to make a correct fault judgment. If the key fob doesn't open the door, don't worry, don't forget that you can also unscrew it with the mechanical key.

The driver is noisy and the door induction is closed, and the instrument is still not closed, which means that the door induction system is faulty, and the cab door induction system needs to be rematched, and the specific operation steps are as follows

1. Open the door of the car driver's side.

2. Press the brake pedal of the car to prepare to start the engine.

3. Press the car's one-button start button.

Fourth, the instrument light of the car is fully lit up, which proves that the engine is started.

5. Press the top of the toggle lever on the right side of the steering wheel, press and hold it for more than 5 seconds, and the match can be completed.

One is caused by poor contact. One is that the conduction signal is not transmitted to the central control. During the inspection, you can adjust the interior lights to open the door and turn on the lights, and turn off the door.

Then close the door. If the lights in the car are turned off, the cause of poor contact can be ruled out. Check whether there is a break point between the conduction signal line and the faulty lamp and whether the faulty lamp is broken.

If the door is closed and the lights in the car are not turned off, check the vicinity of the door bayonet.
