Generally, it is located below the windshield. The air conditioning intake may vary depending on the brand and model of the vehicle. The locations of car air conditioning intake vents are introduced as follows: 1. There are two air intakes for car air conditioning - one is for the external circulation system, located in the air filter box under the front windshield; 2. The other is for internal circulation, typically found as two circular vents on both sides of the dashboard inside the cabin. Most vehicles' external circulation intakes are equipped with air filtration devices such as pollen filters or dust filters, while most internal circulation systems lack intake filtration devices.

Generally speaking, the air intake vent of the car's air conditioning system is located beneath the plastic cover panel under the front windshield. After driving for so many years, I always pay special attention to cleaning that area during car washes. It's the most prone spot for accumulating leaves and dust. Last time, leaves blocked the air intake, causing a musty smell whenever I turned on the AC. The mechanic taught me to clean the mesh with a vacuum cleaner, and it indeed worked much better. Now during seasonal changes, I even disassemble the cover panel myself to inspect, since the air intake is connected to the cabin air filter – keeping it clean ensures fresh air inside the car. The exact location is near the base of the wiper arms; lifting the hood reveals the black plastic grille.

I've been running an auto repair shop for over a decade, and the air conditioning intake vents are typically located under the windshield's deflector panel. This design primarily considers rain protection and dust prevention, as rainwater flows down the glass and is less likely to enter. However, be careful not to drop small items like parking tickets into the grille. Just last week, a customer slid their parking card in, causing unusual noises. For cleaning, first remove the wiper arms, then lift the plastic cover upwards. DIY is completely feasible, as many video platforms have tutorials demonstrating the procedure.

Actually, the location of air intakes varies among different vehicle models, and I've researched this. For sedans, it's usually at the edge of the engine compartment below the front windshield, while my SUV has it slightly behind the grille. When I first bought the car, I was also puzzled about its location. Later, when I turned the AC to maximum airflow and felt around the hood gaps, the spot with noticeable suction was the intake. Nowadays in summer, I avoid parking under trees to prevent leaves from falling in and causing mold. I recommend cleaning it every six months—just use a soft brush and a car vacuum cleaner. There's absolutely no need to waste money at the 4S shop.
