Car for repair (1) air conditioner failure 7-step removal (with list of tools)
The aim is to teach the owner how to maintain his car scientifically, to fine-tune the vehicle when there are minor problems, and to learn how to get a mechanic to fix the car。
With regard to vehicle handling and maintenance care, we have come to cope as far as we can, and the owner's friends should have been familiar with those oil checks, and the tips of how to fix the car and how to judge the course of repairing the car are the focus of our paper。
The owner doesn't have to learn to fix the car
A common paraphrasing of vehicle repair was used to identify fault points and replace damaged parts. While there is some reason for this analogy, it is far from being so simple. No one with a little mechanical common sense, except to open the hood, and to see the complex lines of the pipeline will faint. In fact, more vehicles are being repaired instead of large bodies such as engines, and more are being replaced by repairing some perishable parts. For example, motors, electricians, belts, water tanks, silencers, batteries, spark plugs, tatter lines, brakes, various bearings and lights. As owner, you don't know how to diagnose car problems, but you have to be able to judge whether the diagnosis made by the mechanic is reasonable。

What are you going to do about it
Cars are mainly designed to do their own repairs and require specialized tools and suitable premises to operate, so most types of malfunctioning owners cannot do so independently, even if they understand how to operate. For some ordinary diy self-service repairs, however, simple tools can be purchased that do not cost much to buy imported tools, and the economy is sustainable。
1 a set of rotors (9-24 mm)
Two, one round, one round. Hands
Three, spark plug wrench
Four, oil filter wrench
5. Oil basins can be replaced with similar tools available at home。
Six, one of our own car repair manuals
7. Other tools for application

How to learn how to fix a car, how to fix one's own car:
1. Learning about vehicle repair (the topic: seeing that the tutor will introduce you to some simple and practical routine repairs, please pay attention
2. Many advanced garages now have transparent workshops, short-term maintenance, while the owner can sit in the lounge to observe all the work of the workshop workers through transparent glass, and more advanced computer screens are available for the owner to observe. Most people look at the screen and are reassured, while some of the mean owners know how to ask about vehicle-related failures and solutions when they lift them。
Three, many people think that i have learned to fix cars, at least to prevent fraud, and more often, to help car mechanics diagnose car failure. It is only with a certain level of mechanical common sense that vehicles can be properly identified and judged in order to be available to masters to diagnose failures。
4. Learning to repair their own cars will increase their reliability, since they are not necessarily self-inflicted, but they are clear as to where they have been and provide solutions to the problem。

The downside of repairing your own car:
1. If it is decided to do so on an occasional basis, the oil must be prepared psychologically, especially when the oil is changed. Although some people say they love cars like gasoline in their veins, no one likes car oil. Rubber gloves can reduce some oil pollution problems。
2. Most car owners are not professionals, and the result of this knowledge is the dismantling of the east wall to supplement the west wall. On the way to learning, countless steps are needed to reach the successful side。

Main performance: usually only when car air conditioners are installed。
Solutions: reconnecting the zero line。
2. Check if it was internal or external fan damage or electrical damage

(a) main performance: if the outer fan is broken, the main manifestation is overtemperature or overpressure; if the internal fan is broken, it is shown as internal frost。
Solutions: replacement of inner (outside) aircraft fans or electric capacitors。
3. Check whether refrigerant leaks or refrigerant quality pass

Main performance: automobiles work both inside and outside, compressors work, but car air conditioning is not cooling。
Solutions: check whether refrigerants are added or replaced in a timely manner as a result of leakage or quality problems in car ac refrigerants。
4. Check the compressor's capacitor damage or malfunction

Main performance: automobiles work both inside and outside, compressors do not rotate and cause overheating。
Solutions: check if the condenser's capacitor has been exposed or damaged and if damage has to be replaced in a timely manner。
Check the car air-conditioning room for temperature temperature levels

Main performance: air conditioners reach a certain temperature and are put on hold。
Solutions: reactivate the air conditioner after a proper break and close for a period of time。
6. Check whether the internal or external control panels of the air conditioners are malfunctioning
Main performance: unresponded or “disturbed” car air conditioners after they were turned on。
Solutions: it is recommended that maintenance should be checked at point 4s or at a professional repair shop, and that no self-dismantling should take place。
List of tools needed to repair air conditioner failure:
Following the diagnosis of car air conditioner malfunctions, in addition to the leakage detection tool and refrigerant recovery loaders, repairs will need to be done with specialized maintenance tools, as described below, as well as the installation of commonly used detection tools。
(1) dpr。
Mainly used for checking and judging the working state and malfunction of the refrigeration system, it consists of a high and low-pressure table with three interfaces to three rubber hoses, each of which completes a vacuum in the refrigeration system and a coolant operation。

(2) refrigerant injection valves。
When refrigerants are injected into the refrigeration system, the injection valve may be placed on the refrigerant tank and the rotary refrigerant may be injected into the valve handle. Valve needles piercing refrigerant tanks can fill refrigerants。

(3) vacuum pumps。
After installation or repair, a vacuum in the refrigeration system is required before refrigerants are filled. Otherwise, air and moisture in the refrigeration system can cause pressure in the system to rise and expansion valves to freeze and affect the normal operation of the refrigeration system。

(4) other maintenance tools。
In addition to the tools and equipment described above, a variety of wrenchs, cutters, benders and boosters are required. The compressor should also be equipped with special tools such as a clutch wrench, a bolted nut drum, a hexagon tube and a gas tank cap breaker。

Summary: learning about the diagnosis and overhaul of car ac failure is to help you understand how air conditioning works and the mechanical structure of the car. Understanding the tools needed to repair the air conditioners will also help you to judge whether the repair shop of your choice has a basis to help you solve the problem。
