What to Do When the Car Air Conditioning Stops Cooling?

Solutions for when the car air conditioning stops cooling: 1. Check the coolant temperature: When the car ECU detects that the water temperature is too high, it disconnects the compressor control circuit, preventing the compressor from working, resulting in no cooling. 2. Check the engine speed: A normally functioning car, whether idling or accelerating, operates within a controllable range. If the engine speed is below 600 RPM or above 5500 RPM, the compressor will not work. 3. Check the air conditioning system pressure: The car air conditioning system has high and low pressure lines. There is a pressure switch in the high-pressure line. If the system pressure is too low or too high, the pressure switch disconnects to protect the compressor, preventing it from engaging, and the compressor stops working. 4. Check the evaporator temperature: The evaporator has a temperature sensor. When the sensor detects a temperature below 3 degrees Celsius, the car ECU will also disconnect the compressor relay, preventing the compressor from working.

What is a position lamp?

Automotive position lamps refer to the front and rear position lights on a vehicle. Here is additional information: 1. Position lamps and clearance lamps are quite similar. The location of position lamps varies depending on the vehicle model. On passenger cars, position lamps are commonly referred to as parking lights. For larger vehicles, the lights on the front and rear sides are called clearance lamps. On trucks, position lamps are often called side marker lights. 2. Clearance lamps are the outermost lights at the front and rear of a vehicle. Large trucks also have clearance lamps on the roof and sides. The term "clearance lamp" can be interpreted literally: "clearance" indicates its warning function, while "lamp" refers to its role in outlining the vehicle's profile. Therefore, clearance lamps serve as warning lights to alert other vehicles. Installed along the edges of the vehicle's roof, these lamps indicate both the height and width of the vehicle. 3. The next setting after position lamps is low beam, while high beam refers to the main headlights.

What is the normal coolant temperature for a car?

The normal temperature is indicated by the center of the needle--90℃. Here are specific details about coolant temperature: 1. Coolant is an essential part of a car's engine. It circulates within the engine cooling system, carrying away excess heat generated during engine operation, allowing the engine to run at its optimal working temperature. 2. Both excessively high and low temperatures can cause damage to the car. Lower temperatures indicate stronger heat dissipation. Excessively low temperatures mean greater heat loss through dissipation, and lower working temperatures result in higher fluid viscosity. Increased viscosity leads to greater resistance in moving parts, reducing output power. 3. Excessively low cylinder wall temperatures prevent proper formation and combustion of the air-fuel mixture, increasing fuel consumption. The engine becomes harder to start, operates with greater resistance, and fuel evaporation becomes difficult. Unvaporized fuel due to low temperatures can wash over cylinder surfaces, damaging the lubricating oil film and accelerating component wear.

How to Use Turn Signals When Entering a Roundabout

There are three scenarios for using turn signals when entering a roundabout: turning left upon entering, going straight upon entering, and turning right after entering. The details are as follows: Turning left upon entering: If the vehicle intends to turn left, it should prioritize selecting the left lane inside the roundabout. Since the vehicle needs to merge from the outer lane to the inner lane, it should activate the left turn signal when entering the roundabout. Before exiting the roundabout, the driver should switch to the right turn signal in advance to give sufficient warning to vehicles behind. After ensuring safety, the vehicle should start changing lanes from the inner lane to the outer lane and finally exit the roundabout. Going straight upon entering: If the vehicle intends to go straight, it should prioritize selecting the middle lane inside the roundabout and merge into the middle lane without obstructing vehicles behind. Since no lane change is required after entering the roundabout, the left turn signal is unnecessary. When preparing to exit the roundabout to continue straight, the vehicle may need to cross the right lane inside the roundabout, potentially hindering vehicles behind. Therefore, the right turn signal should be activated to alert other vehicles before exiting the roundabout. Turning right after entering: If the vehicle intends to turn right to another intersection, it should quickly select the right lane inside the roundabout to exit or may choose to turn right from the outer lane. The situation when entering the roundabout is similar to going straight, so the left turn signal is also unnecessary. After selecting the corresponding intersection, the driver should activate the right turn signal in advance and exit the roundabout by turning right after ensuring safety. Typically, roundabouts are designed with four lanes: the left lane for left turns, the middle two lanes for going straight, and the right lane for turning right to exit the roundabout.

What Causes Rapid Consumption of Antifreeze?

Rapid antifreeze consumption is generally caused by the following three reasons: 1. Radiator damage: Poor sealing of the upper and lower water chambers leads to antifreeze leakage. 2. Overflow tank: Loose connections at the water pump interface and cooling system pipe joints result in poor sealing and antifreeze leakage. 3. Cylinder head gasket damage: Excessive flatness deviation, warping of the cylinder head and block mating surfaces, or loose cylinder head fastening bolts allow high-temperature, high-pressure gases from the cylinders to enter the cooling system, causing rapid coolant consumption. Additional information about antifreeze: The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when the vehicle is parked in cold winter conditions. Many people think antifreeze is only used in winter, but in fact, it should be used year-round.

How to Set Automatic Mirror Tilt When Reversing?

To set the automatic mirror tilt when reversing, first engage reverse gear, then press and hold the driver's seat memory button on the left side until you hear a sound, indicating successful memory. Configurations with seat memory have this function. When reversing, rotate the mirror adjustment to the R position, and it will automatically tilt down. Below are the detailed steps for setting the automatic mirror tilt when reversing: 1. Power on the car but do not start it (press the start button without stepping on the brake); 2. Set your memory seat positions 1, 2, and 3, and select your seat position; 3. Choose the side mirror you want to set by pressing the mirror adjustment selection button (left or right); 4. Step on the brake, shift to R gear, and the selected mirror will automatically tilt down to the factory preset position. Use the 4-way adjustment button to set it to your desired position; 5. Press and hold the seat memory button (1, 2, or 3) for about 2 seconds, depending on which memory position you selected; 6. Step on the brake, shift to P gear, and press the mirror adjustment selection button once more to complete the setup.
