Where is the drainage hole for the Mazda6 car door?

[Amy]

The drainage holes for the Mazda6 car door are generally located in areas such as the fuel tank cap, engine compartment, lower part of the door panel, and sunroof. The most prone to clogging areas are the sunroof and engine compartment. Specific details are as follows: 1. Air conditioning drainage hole: It discharges the condensate water generated during air conditioning use. The drainage outlet is usually located at the lower part of the evaporator box, connected to the chassis via a hose. You may notice a puddle of water under the car after the air conditioning has been running for a while. If the drainage hole is clogged, water may enter the passenger compartment through the connection, soaking items like floor mats. 2. Engine compartment drainage hole: It is typically located on both sides of the front windshield wipers, with one on each side. The engine compartment is a relatively open environment, so wastewater and debris can flow into it along the windshield. Engineers have designed a water barrier at the rear of the engine compartment, along the lower edge of the windshield, and placed drainage holes in the barrier.
