The reason why the Corolla AC button does not light up is that the C switch is damaged or has poor contact, so the AC light naturally does not illuminate. Alternatively, the air conditioning fuse may have blown, which is located in the fuse box in the engine compartment. You can check if the fuse has any issues. If the fuse is broken, there will be no power supply, causing the light not to work. If no issues are found, it is best to visit a 4S shop or repair shop for a professional inspection and repair. Air Conditioning: In some car models, to activate the air conditioning cooling, you must first turn on the blower switch and adjust the temperature knob to the cooling position. For automatic air conditioning, you can set a temperature and then press the AUTO button. The automatic air conditioning will adjust the interior temperature accordingly, and the ACC light will then illuminate. Precautions: Under normal cooling conditions, when the car's AC is turned on, you should first activate the internal circulation and then switch to external circulation. This effectively limits the airflow inside the vehicle while also reducing the interior temperature. When starting the car, if you need a cooling effect, turn on the internal circulation first. Once the interior temperature stabilizes, switch to external circulation to allow fresh oxygen to enter, creating a safe environment for the passengers.

How to Repair High Water Temperature in a Van?

Find a safe place to park, turn on the hazard lights, place a triangular warning sign after parking, and let the car idle without turning off the engine. After parking the car, open the hood, slightly unscrew the radiator cap, and wait for the steam to escape before fully opening it. Check if the coolant is sufficient, but do not add it immediately as the temperature is still too high. Inspect the radiator hoses for any leaks.

Solutions for Car Air Conditioning Not Cooling Properly

Solutions for car air conditioning not cooling properly are as follows: 1. Insufficient refrigerant in the air conditioning system can lead to reduced pressure and less heat being removed, resulting in poor cooling performance. In this case, the refrigerant needs to be refilled. 2. A dirty condenser can also cause poor cooling. You can rinse the condenser directly with a water hose or remove it for thorough cleaning to ensure cleanliness. 3. Check the air conditioning filter. If the car hasn't been serviced for a long time, a dirty filter may affect the cooling performance. 4. Clean or replace the air conditioning filter if necessary.

What is the function of the car OFF button?

The OFF button in the car is used to deactivate the vehicle stability control system. The vehicle stability system is enabled by default. If you need to turn it off, press and hold the OFF button. The function of the vehicle stability system is to prevent skidding and loss of control when the vehicle is cornering at high speed. If the front or rear wheels, which have driving and steering functions, start to slip, the ESP will automatically brake other wheels and intervene with the engine management system. There are several situations where you may need to turn OFF the system: 1. When the vehicle is stuck in mud or sand during off-roading. 2. When aggressive driving such as drifting is required. 3. When snow chains are installed on the vehicle.

What to do if the scratch cannot be wiped off but the primer is not damaged?

Touch with your finger. Generally, if you cannot feel obvious unevenness when touching the scratch, it means the primer is not damaged. Take out a clean towel, wet it, and quickly wipe off the black marks with force. Note that the towel should not be too wet, as this may damage the primer. Use a polishing wheel with polishing oxidizer to remove the oxidized layer attached to the car surface, smooth out fine scratches, and allow the chemical to penetrate the paint for a restorative effect.

What is the best spraying method for automotive 2K paint?

First, use a blower (spray gun) to thoroughly dry any water in the car's seams, and cover areas that do not require painting with newspaper. Then, begin mixing the paint. Perform sanding, and apply the sealer primer in the correct proportion by brushing. Do not skip applying the sealer primer based on non-professional advice. Ensure even gun movement. Start by applying two thin coats of paint over the putty and let them dry briefly. Then, spray two more coats evenly from the bottom using a 3/1 gun movement technique and allow to dry.
