Why is the car AC light not on and the air conditioner not working?

How to Clean Car Air Conditioner Thoroughly?

Cleaning methods for air conditioner are as follows: 1. Clean the air conditioner filter. The normal lifespan of the original car air conditioner filter is one year. Regular cleaning of the air conditioner filter will maintain fresh air inside the car. 2. Clean the air conditioner ducts. Ordinary air conditioner cleaners and disinfectants can be used for cleaning. Before cleaning, shake the air conditioner cleaner well, then spray it directly onto the filter. The built-in suction of the air conditioner will draw in the cleaner, thereby cleaning the ducts. 3. Clean the evaporator. When cleaning the evaporator, it is necessary to first remove the air conditioner pipes and the evaporator. It is recommended to have this done at a car maintenance or repair shop. 4. Clean the air conditioner condenser. Open the front bumper of the car to expose the condenser, then use a water gun to clean the dirt on the condenser.

How to Measure Engine Cylinder Pressure?

Cylinder pressure measurement steps are as follows: 1. First, use compressed air to clean the dirt around the spark plugs. 2. Remove all spark plugs. For gasoline engines, also disconnect the secondary high-voltage wires of the ignition system and securely ground them to prevent electric shock or fire. 3. Insert the conical rubber tip of the dedicated cylinder pressure gauge into the spark plug hole of the cylinder being measured, align and press it firmly. 4. Fully open the throttle (and the choke if equipped), and use the starter to rotate the crankshaft for 3-5 seconds (no less than 4 compression strokes). Stop rotating once the pressure gauge needle indicates and maintains the maximum pressure reading. 5. Remove the pressure gauge, record the reading, and press the one-way valve to reset the gauge pointer to zero. Measure each cylinder in this manner, performing at least 2 measurements per cylinder. Take the arithmetic average of the results for each cylinder, compare them with the standard values, analyze the results, and determine the working condition of the cylinders.

What Causes the Car to Not Accelerate When Pressing the Gas Pedal?

Here are the reasons why the car does not accelerate when pressing the gas pedal: 1. When the gas pedal is pressed, the throttle cable moves the throttle valve (also known as the accelerator). The throttle valve is equipped with a position sensor, and the control unit determines the throttle opening based on the signal from this sensor, calculates the corresponding signal voltage, and then determines the fuel injection volume accordingly. If the throttle position sensor is dirty or the voltage is imbalanced, it can cause an electronic throttle malfunction, resulting in the car not accelerating even when the pedal is fully pressed. 2. If electronic throttle issues are ruled out, the problem may lie in one of the three systems: engine intake, fuel delivery, or ignition. The throttle position sensor signal is crucial for proper engine operation, which requires sufficient air. If there is a leak or blockage in the intake system, pressing the gas pedal may lead to reduced power, inability to increase RPM, and vehicle shaking. 3. The fuel system is vital for the engine. Using low-quality gasoline can damage components such as the fuel pump, catalytic converter, or pistons, directly affecting engine power and potentially causing stalling or failure to accelerate.

What does it mean when a car displays 'Check Engine System'?

The reasons why a car displays 'Check Engine' are as follows: The message 'Check Engine System' means that the engine needs to be inspected to see if there is a fault in the emission system or an issue with the oxygen sensor. The owner should take the car to a 4S shop to read the fault code and identify the specific cause. Extension: 1. The engine consists of three major parts and five service systems: the engine block assembly, the crank-connecting rod mechanism, the valve train, the ignition system, the starting system, the lubrication system, the cooling system, and the fuel supply system. 2. The functions and basic components of each part are as follows: the engine block assembly supports the entire engine and also houses the crankcase, cylinders, etc.; the crank-connecting rod mechanism converts the reciprocating motion of the piston into the rotational motion of the crankshaft, which is then output, including components like the connecting rod and crankshaft; the valve train supplies fuel and air to the cylinders and expels exhaust gases, composed of components such as tappets, valves, and control circuits.

What is the fuel tank capacity of the Borgward BX5 in liters?

Borgward BX5 has a fuel tank capacity of 60 liters, as announced by the automobile manufacturer. Owners who have purchased the Borgward BX5 can also check this information on the vehicle's configuration sheet. The Borgward BX5 requires 95-octane fuel, with a fuel consumption ranging from 5.8 to 7.6 liters per 100 kilometers. A full tank can cover a distance of approximately 500 to 600 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safe fill level, leaving some space between the safe fill level and the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

How to Display the Remaining Mileage on the Fuel Gauge in a Land Rover?

Land Rover displays the remaining mileage that can be driven with the current fuel level as follows: 1. Press the brake pedal and press the one-touch start button. At this time, the dashboard will light up, indicating that the vehicle's power is fully connected. 2. Then press the function selection button on the multifunction steering wheel and press the OK button to confirm the operation. At this point, the remaining mileage based on the fuel level will be displayed on the dashboard. The fuel gauge shows 0 km under the following circumstances: 1. When the fuel gauge shows 0 km, the fuel warning light comes on. This is actually just a reminder to refuel, and there is still some fuel left in the tank. 2. In this situation, a typical family car can still drive about 20-30 km, but the exact distance depends on the vehicle model, fuel tank size, and fuel consumption. In the city, you can usually make it to a gas station. If you're on the highway, it is recommended to drive at a steady speed in the right lane and turn off the air conditioning to maximize fuel efficiency.
