1. The sound is caused by sand in the space between the car window and the strip.
2. Noise caused by aging and hardening of the window glass strip due to glass friction;
3. The bearing of a certain component of the window mechanism is damaged.
The first situation: this is the most common. It sounds very faint but sharp. Consider whether there was heavy rain or strong wind before the abnormal noise on your car window.
Generally, car windows are designed with double sealing strips. There is a layer above and another layer below. The noise is caused by sand penetrating the layer below.
The correct method: wipe the car window first, then lower it down, then raise it up. Try going back and forth two or three times. If the sand is shallow this may be the case. essentially be cleaned bythe sealing strip.
If it still doesn't work, wet the car window, then raise and lower the window. You will see a mark where the sand is. This is where the sand is. and find a thin sheet. Stuff the wet towel with something hard, place it in the gap of the second layer of sealing tape, and wipe it several times to solve the problem.
The second situation: This is usually an older car. Spraying a little lubricant into the cracks of the car window can alleviate the problem. If you want to solve the problem completely, purchase a pair of exterior window trims. online and replace them. It's very simple and inexpensive, you can replace it yourself.
Third situation: It is recommended to go to a repair shop to repair. Those with strong practical skills can replace the entire setble window regulator by themselves.
Are the car generator and electric motor the same engine? If not, what is the difference between the two? And the starter? Where are all three installed in the car?
As follows:
1. The battery is charged but the vehicle cannot start. This symptom is probably due to the fact that the fuse responsible for starting the engine is blown. Please pay attention to When you find that the vehicle cannot start, remember not to light continuously. Continuous ignition will cause the battery to continuously discharge and result in an embarrassing situation of complete power loss.
2. When the vehicle is driving, the tachometer displays normally, but the speedometer displays zero, and the ABS indicator light comes on at the same time. This indicates that the fuse corresponding to the ABS is blown. Some irregular companies transport vehicles. Sometimes the fusible which manages the ABS will be removed so as not to increase the mileage, but the hidden dangers that this entails are very great. A vehicle that has lost ABS will be very dangerous in an emergency.
3. If the glass water switch does not spray when you press the glass water switch, it may be due to a foreign object blocking the nozzle or the nozzle being frozen by the cold in winter. time, remember not to press the glass water switch continuously for a long time. Pressing the switch will cause the motor to overheat and blow the corresponding fuse.
Virtual connection of the fuse means that the fuse is not connected in series in the power circuit as required. Because the fuse is not reliably connected to the power circuit, the power circuit is not powered.
The power output circuit power supply is unstable and turns on and off whenIf the fuse is not reliably connected to the power line, it will cause unstable operation or even damage to many electrical appliances.
The generator and the starter of a car are two different devices with different structures!
The generator is a special device driven by an internal combustion engine for charge the battery and supply electricity to the entire vehicle. The power is only a few! one hundred watts!< /p>
The starter is a high-power, low-voltage motor that starts the internal combustion engine! Its starting current reaches hundreds to thousands of amps!
The starter is the biggest! engine on the car! Other wiper motors, window The motors are all small motors!
The generator is installed in front of the internal combustion engine!
The starter is installed in the part lower part of the comb motorinternal usage!
