Car Repair Technology Sharing

 This car today is actually because of a very small fault cause the vehicle can not start, first of all, we test the ignition, the vehicle is indeed unable to start, after checking, not supplying fuel nor power, after the owner described, in the garage to replace the crankshaft position sensor, replace the gasoline pump, still can not solve the problem. In fact, most models have anti-theft, regardless of whether your anti-theft is the original, or later installed? If the anti-theft lock up will lead to the vehicle can not start, after my test, the car remote control can not lock the door normally, the first thing to start with his remote control, I suspect that his remote control locked up the anti-theft, resulting in the vehicle can not start, must first fix the remote control to say, after some inspection, found that this car has a broken wire place, see is here, all models are prone to broken wire location, the car door and the a-pillar between a broken wire. There is a line bet...

 Today's car is the trunk, can not be remotely unlocked, but the use of mechanical keys can be unlocked, like this case is generally the door lock motor is broken, the following we do it yourself to repair, first, we use the mechanical key to open the rear tailgate, with a screwdriver to unscrew the snap of the interior panel, and then use the snap pry plate to pry off this snap, remove all the interior panels, after the snap, the entire interior panel will After removing the interior panel, we can see the unlocking motor, the motor has been burned and melted, we remove the two screws holding the door lock, after removing it, the whole mechanism of the door lock is removed, we just need to replace the motor, remove the two fixing screws above the motor, the burned link is taken out, we put the new motor back in, tighten the screws, insert the power plug and put the whole motor back in. Plug it in, put back the whole interior panel, cover the rear trunk, press the remote control ...

In the process of using the car, you may often encounter the wiper nozzle does not produce water, so what exactly is the cause of the wiper no glass water spray out? And how should we solve it? Today we will talk to you about the common causes of failure and solutions to the car wiper spray system. The car's wiper spray system is generally composed of control switches, glass water, reservoir, water spray motor, fuse and guide pipe and other parts. That is to say, the damage to one of the above parts will lead to the vehicle wiper nozzles do not produce water failure phenomenon. Below I will talk to you about the most common causes of failure, which are the parts most likely to be damaged. Wiper does not spray water causes and solutionsFirst, the windshield under the wiper nozzle blockage caused by the use of a long time, the internal nozzle generally accumulate scale, or stained with dust and other impurities, thus causing the blockage of the failure phenomenon. In the solution, we...

 Today this car has only run more than 20,000 kilometres, the engine shaking particularly strong, idle speed is also normal, the dashboard also does not have any fault lights, the owner responded to the fuel consumption than before to much higher. When this happens, it is usually caused by the aging of the spark plugs, and many people want to go to the repair shop once they hear that they want to change the spark plugs, now the labor costs are very high, go to the repair shop for a change, no several hundred dollars is not possible. Today we replaced the spark plugs ourselves. I bought new spark plugs from the internet and it only cost me a few tens of dollars, and I was given a set of tools to remove them. Next, let's start replacing it, unplug the ignition coil, the top plug, pull out the ignition coil, the spark plug is underneath, next we use the special spanner for spark plug to take it out, you see this old spark plug gap is not very big? If the spark plug gap is too large...

 The owner of the car has been suffering from a problem for half a year, which is that the car takes two or three times to start each time and the fuel consumption is particularly high. The owner has been to the garage before to change the spark plugs, clean the throttle and change the fuel pump, all to no avail. If this is the case, I think his injectors are dirty, today we come to give him a cleaning, pull off the filter, no need any tools, with a hand break off, and then put him to the side, see, this is the four injectors, we unplug the top, just unscrew the two screws, the injectors are taken off. You see, this injector nozzle is all above the carbon and sludge, it will lead to poor atomization of oil injection, and ultimately lead to bad firing and fuel consumption problems, cleaning is also particularly simple, we use paper towels to plug the four holes of the injector nozzle to him first, so as not to fall into something, we find a plug of the injector nozzle, find two wire...

 The car we came across today had a battery that was constantly running out of power and was preventing the car from starting, so we came over to see if we could fix it for her? We got in the car to start the vehicle first to try and unscrew the key door to start the vehicle and the dash lights went out quickly. In cases like this the battery is usually dead, so we looked for a backup power source and let the vehicle start before doing a check. With the cause of the problem found, see this battery symbol light? When this battery symbol light comes on, it means that the car battery is not charging. Let's take a multimeter and measure its power output, it is only a little over 12 volts, the normal charging voltage should be over 13 volts. Let's take the generator out and see what's going on. Let's take the generator apart and see what's wrong inside? In fact, this generator is very simple, the rotor rotates and cuts the magnetic lines to produce alternating current,...

 The car has been in the car park for a month today and now the vehicle won't start, so I'll see if I can get it fixed for him. The owner has just contacted the garage and the garage has come and checked it out and said they need to overhaul the engine.Let's get in the car and start it and see what the cause is. It's true that the car won't fire. There are generally three reasons why a car won't start, the circuit has to be normal, the oil circuit has to be normal and the cylinder pressure has to be sufficient so that the car can start properly. The circuit is relatively simple to check, we first check the circuit, lead out a spark plug, see if there is fire? Do you see any spark? The circuit is normal, we then check the oil circuit, unplug the oil supply to the engine, we find a bottle to catch it, start the vehicle to see if there is oil flowing out? Do you see it? The fuel line is also normal, we put this fuel line back on him, pay a little attention when i...

 This car engine shaking today is particularly strong, in fact, we encounter this situation, simply do not need to go to the repair shop, like this car engine shaking serious situation, generally are caused by the lack of cylinders, then we how to quickly determine? Is it a cylinder shortage problem? In fact, it is very simple, we will unplug the ignition coils one by one. Observe the engine shuddering, you can quickly distinguish which cylinder is not working? Now we start unplugging the ignition coil from the first cylinder, the engine shakes even more, even to the point of stalling, we plug it in, the engine goes back to the previous shaking state, continue unplugging the ignition coil from the second cylinder, the engine also shakes even more, even to the point of stalling, we plug it in, the engine goes back to the original shaking state, then unplug the ignition coil from the third cylinder, the engine does not respond. Then we unplugged the ignition coil of the third cylinde...

Today, the owner of this car, the owner drove and then stalled, and then it will never start, ready to call a tow truck, I said I will help you see if it can be repaired? We first get into the car to start the vehicle to try, it really can not start, this does not start the fault, there are generally two possibilities, one is the oil circuit failure, one is the circuit failure, we first pick the simplest test, unscrew the spark plug, start the vehicle to see if there is a spark? See if there is no spark Our next step is to see if the oil line is clear? Find the oil line test point on the engine and start the car to see if it supplies oil? See, no oil supply either. The oil and circuitry are controlled by the engine's computer board. How many major signals does the engine computer pick up before supplying oil and power? The crankshaft position sensor is one of the most important signals, so let's take it off and have a look. This is it. The cause of the fault has been found, so ...
