What to do if the car battery is dead?

If the car battery is dead, you can push the car to start it. You need to push the car from the front, back, left, and right of the car, reach a certain speed, shift into first gear, release the clutch and add gas to start. You can also find a car with a battery that has power, and connect the batteries of the two cars in sequence with a connecting wire. Or you can use a traction rope to tie the two cars together and start the car by pulling it with external force.

This method requires many people. Although it is simple, it is time-consuming and laborious, and it is only suitable for manual transmission cars. The driver sits in the car and drives, and the other people push the car in front, behind, left and right. When the car reaches a certain speed, the driver puts the car into first gear, then quickly releases the clutch pedal, and steps on the accelerator to start the car.

This method can be used for both manual and automatic transmission models, provided that there are other cars nearby. First find a car with a charged battery nearby, move the two cars close together, open the front cover, and connect the batteries of the two cars with a connecting wire. Connect the positive pole to the positive pole, and the negative pole to the negative pole. Do not reverse the order, otherwise the current will be too large and burn the battery.

Prepare a strong towing rope, tie the heads and tails of the two vehicles tightly, and then start towing and starting. The speed should be slow when starting. The driver of the front vehicle slowly pulls the rear vehicle to ensure the speed of both vehicles. Pay attention to driving safety. When the rear vehicle starts, notify the front vehicle in time to avoid the rear vehicle suddenly rushing towards the front vehicle.

What to do if the car windshield is frozen

If the front windshield of the car is frozen, you can directly rinse it with warm water. Take warm water of about 40 to 50 degrees, wipe it several times with a rag soaked in water, and then rinse it with warm water. If you are not in a hurry, you can drive the car to a sunny place, let the sun shine, and the ice on the glass will slowly melt by itself.

The front windshield of the car can be melted with warm water. Take a basin of warm water at about 40-50 degrees, soak it with a rag and wipe it continuously for about 3 times. Then rinse the front windshield with warm water at about 40 degrees to melt the ice.

When the car windshield is frozen, you cannot use hot water to melt it. The hot water is too high, which will cause a large temperature difference. The windshield may burst due to thermal expansion and contraction. Do not use hard objects to shovel, which may scratch the glass. Do not turn on the wipers, which will cause damage to the wiper blades and motor.

If you are not in a hurry, you can drive the car to a sunny location to let the ice melt naturally. In winter, due to the low temperature, the front windshield is easy to freeze, but this can also be avoided by driving the car to an underground parking lot when parking, or applying a layer of antifreeze windshield water.

What to do if the car air conditioner has no hot or cold air

If the car air conditioner has no hot or cold air, it may be because the refrigerant has leaked out. In this case, the leak needs to be repaired and the refrigerant needs to be replenished. It may also be because the air conditioning pump is damaged internally, or the condenser fins are too dirty, causing the pressure and temperature of the air conditioning system to be too high. In order to protect the air conditioning system, the car system will stop the air conditioning.

When the car air conditioner has no hot or cold air, it may be caused by refrigerant leakage in the air conditioning system. In this case, it is necessary to check whether the pipes, air conditioning pump, condenser, evaporator and other components in the air conditioning system are damaged and cause refrigerant leakage. If there is a leakage, it is necessary to repair the leak or replace the parts in time.

The air conditioning pump is an important component to ensure the normal operation of the car air conditioner. If the piston ring inside the car air conditioning pump is damaged, or the clutch suction cup is damaged, the air conditioning pump will not work and the air conditioner will not be able to cool or heat.

When the condenser fins in the car's air conditioning system are too dirty, the pressure and temperature of the air conditioning system will be too high. In order to protect the air conditioning system, the car system will stop working and the air conditioning will not cool. In this case, you can use the speed of the car to dissipate the heat of the air conditioning system while driving the car, and the air conditioning system will cool down after the temperature drops.
