Detailed introduction is as follows: 1. Air conditioning drainage hole: Location: Generally installed below the evaporator, connected to the chassis with a hose. When the car's air conditioning is turned on, condensation water forms during the heat exchange process of the evaporator. The hole that drains this water out of the car is the air conditioning drainage hole. After running the car's air conditioning for a while, you will notice a puddle of water underneath. 2. Engine compartment drainage hole: Location: Usually installed on both sides of the front windshield wiper, with one on each side. The engine compartment drainage hole is the most prone to clogging due to its installation location. Dust, dirty water, and fallen leaves can flow into the engine compartment along the windshield. Moreover, it is very close to the air conditioning intake, making it easy for bacteria to grow in a hot and humid environment. Clogging can cause engine malfunctions and may affect the engine computer in some car models. 3. Sunroof drainage holes: Location: There is one drainage hole in each of the four corners of the sunroof.
