What Are the Reasons for the Car Air Conditioner Fan Not Turning On When Activated?

There are several reasons why the car air conditioner fan does not turn on when activated, including poor contact of the main control switch, damage to the fan motor coil, and detachment of the fan bearing. Poor contact of the main control switch: If the air conditioner switch has poor contact, it cannot control the normal activation of the car air conditioner, and the lack of connection between the two leads to the fan not turning on. Solution: Replace the air conditioner control switch and check for any short circuits in the connecting wires. Damage to the fan motor coil: If the fan motor coil is damaged, the fan cannot receive power normally, resulting in it not turning on. Solution: Use a multimeter to measure the contact resistance of the main control switch. If the resistance is too high or zero, repair or replace the component. Detachment of the fan bearing: When the fan bearing is detached, activating the air conditioner causes the bearing to spin idly without the fan turning normally. Solution: Reinstall and secure the fan bearing. How the car air conditioner works: The car air conditioning refrigeration system consists of a compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower, among other components. These parts are connected by copper pipes and high-pressure rubber hoses to form a sealed system. When the refrigeration system operates, the refrigerant circulates in different states within this sealed system.

What is the difference between OEM headlights and aftermarket headlights?

OEM headlights and aftermarket headlights differ in quality. The housing of OEM headlights maintains its sealing performance for many years without significant aging, while the housing of aftermarket headlights tends to lose sealing performance and show noticeable aging over time. Headlights are a crucial component of a car, serving the primary function of illumination. Also known as car front lights or LED daytime running lights, headlights act as the 'eyes' of the vehicle, impacting not only the owner's external image but also safe driving during nighttime or adverse weather conditions. The use and maintenance of car lights are essential and should not be overlooked.

What is the principle of hybrid power?

Hybrid power works by using both an internal combustion engine and an electric motor to provide energy for the vehicle, thereby driving the car. This results in improvements in fuel economy, comfort, and acceleration. In hybrid vehicles, the electric motor serves as an auxiliary power source to assist the engine, delivering strong and smooth power during normal driving. Hybrid vehicles offer superior fuel efficiency and excellent driving performance. While the engine still consumes fuel, the assistance from the electric motor during startup and acceleration helps reduce fuel consumption, leading to lower fuel costs compared to similarly sized conventional vehicles.

How Long After Touch-Up Painting Can You Wax?

You can wax your car 24 hours after touch-up painting. Here are the relevant details: 1. Car waxing: This is a traditional car care procedure. The primary functions of waxing are waterproofing and protection against acid rain. The wax coating reduces water droplet adhesion on the car body. It also provides protection against high temperatures and UV rays, as the wax film reflects some light, effectively preventing paint aging. 2. Additional information: When a car moves, friction with air generates static electricity. Car wax effectively insulates the body from friction with air and dust. Reduced static means less dust accumulation, and wax also enhances shine, making the car appear newer and more attractive.

What is the function of the powder inside the three-way catalytic converter?

The powder inside the three-way catalytic converter serves to decompose harmful gases and also contributes to environmental protection. Below is relevant information about automotive three-way catalytic converters: 1. Function: The three-way catalytic converter is installed in the front section of the vehicle's exhaust pipe to reduce toxic and harmful substances in automobile exhaust. 2. Quality assessment: When the catalytic converter operates normally, it generates substantial reaction heat due to oxidation reactions. Therefore, performance can be evaluated by comparing temperature differences. Start the engine, warm it up to normal operating temperature, maintain engine speed at approximately 2500r/min, and lift the vehicle.
