Methods to fix car air conditioning not cooling by yourself include: 1. Incorrect gear setting; 2. Insufficient refrigerant; 3. Compressor failure; 4. Clogged throttle valve and idle valve of the throttle body. Solutions for air conditioning not cooling: 1. Replace the refrigerant; 2. Replace the compressor; 3. Clean the dirt from the throttle valve and idle valve of the throttle body. Air conditioning, short for car air conditioning system, is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to an optimal state. Its functions are: 1. To provide a comfortable riding environment for passengers, reducing travel fatigue; 2. To create good working conditions for the driver, ensuring driving safety.

I enjoy troubleshooting minor car issues myself, especially when the AC isn't cooling. First, I check if the AC switch is turned on and whether the temperature setting is low enough - sometimes we accidentally turn it off without realizing. Next, I inspect the cabin air filter, as clogged filters are the most common cause. I can easily access it by opening the glove compartment to check if it's dirty; replacing a dirty filter is inexpensive and simple. Then I start the engine with AC on to listen for the compressor's clicking sound - no noise might indicate electrical issues or a blown fuse. The fuse box under the hood can be checked using the manual, and replacing a fuse is straightforward. If everything seems normal but the air remains warm, it could be low refrigerant or a leak, which requires professional tools so I won't attempt that myself. The key is not rushing to the repair shop - checking filters and fuses first saves money and is practical.

Solving AC issues on my own always gives me a great sense of accomplishment. When my car's AC isn't cooling, I jump into action: first, I make sure the AC button is pressed and the fan is set to maximum. Then, I crawl in to locate the air filter—usually found in the glove compartment on the front passenger side. If it's dirty, replacing it with a new one costs just a few bucks and helps prevent odors. Next, I start the car to listen for the compressor's sound. If I don't hear it engaging, I pop the hood to check if the fan is spinning. A faulty fan might mean a loose belt, so I try tightening it, or if it's a blown fuse, I replace it with a new one from the fuse box. For refrigerant issues, I avoid handling refrigerant cans to prevent leaks and injuries, opting instead to look up simple tutorials online. But if the system pressure is too high, I know to stop and take it to a professional to avoid damaging components. As a DIY enthusiast, I always say that basic checks can be done yourself, saving on labor costs.

When the air conditioning malfunctions, my first reaction is safety first. If the car isn't cooling, I'll park in a safe spot to check basic points. See if the cabin air filter is stuck in the vent - if it's dirty, I'll replace it myself to avoid blowing dust. Set the temperature to minimum and test the airflow. If it's not cooling, don't rush to touch the compressor - compressor failure risks electric shock or pipe damage, so I absolutely won't touch it. Is the fan running normally? If there's no abnormal noise, confirm the switch isn't broken. These self-checks I can do myself, but for refrigerant pressure or electrical leaks, I'll immediately call a tow truck to the repair shop - taking risks isn't worth it. Regular AC maintenance helps prevent unexpected issues.
