Door drainage holes are located at the bottom of the doors. Remove the lowest sealing rubber strip to see them. Function of door drainage holes: Car door drainage holes are essential devices on every vehicle, effectively draining rainwater outside during rainy or snowy weather or when the car is wading through water, maintaining a dry interior environment. When the door drainage holes become clogged, water leakage may occur at the door area, leading to a damp interior and musty odors over time. Other drainage holes: In addition to door drainage holes, cars also have drainage holes in the engine compartment, trunk, sunroof, fuel tank, and other areas. Engine drainage holes: Generally located under the front hood, near the windshield. Trunk drainage holes: Usually found where the trunk and rear windshield meet. Sunroof drainage holes: Typically located at the four corners of the sunroof; some vehicles may also have them on the A-pillars and B-pillars. Fuel tank drainage holes: Located inside the fuel tank cap; open the cap to see them.

As an experienced car owner who frequently washes the car myself, the drainage holes of the Lavida Plus are mainly located in four areas: the sunroof, doors, fuel filler cap, and below the windshield. The sunroof drainage holes are the most easily overlooked—they are small holes at the four corners of the sunroof track, where rainwater drains after a downpour. The door drainage holes are near the rubber seal at the very bottom of the door panel; lifting the seal reveals elongated drainage slots. There’s also a hidden drainage hole inside the fuel filler cap, which helps drain any spilled fuel during refueling. The drainage channel below the windshield is located behind the hood gap, specifically designed to collect rainwater from the windshield. Remember to regularly clean these holes with fine wire, especially before the rainy season, as clogged door drains can corrode wiring, and blocked sunroof drains may cause leaks into the car.

As the owner of an auto repair shop with extensive experience servicing Lavida Plus models, I can detail the drainage hole locations: First, there are four tiny drainage holes at the corners of the sunroof, frequently clogged by fallen leaves; Each door has two rubber-covered drainage outlets at the bottom; Lifting the fuel filler cap reveals a small groove with a drainage hole; The U-shaped channel beneath the windshield in the engine compartment also features drainage design. For maintenance, quarterly inspections are recommended, especially before and after the rainy season. Clogged door drainage holes are particularly troublesome as accumulated water can cause window regulator failures. Using compressed air guns for clearance is most efficient - avoid poking with wire to prevent pipe damage. The spare tire well in the trunk actually has drainage holes too, though they rarely get blocked under normal circumstances.

The Lavida Plus has quite user-friendly drainage hole designs, mainly in three areas: There are pinhead-sized drainage holes at the front and rear corners of the sunroof – you can test if they're clear by blowing air through them; the door drainage holes are hidden beneath the bottom rubber seals and can be revealed by gently lifting the seal; inside the fuel filler flap, there's a small hole specifically designed to drain rainwater. For DIY maintenance, just buy a bottle of specialized drainage hole cleaner, spray it into the holes, and rinse with water. Once, my sunroof drainage got clogged, causing condensation on the front passenger footwell carpet – it turned out to be excessive dust accumulation in the sunroof tracks. Now, I clean the tracks with a towel during every car wash to avoid having to remove interior panels for repairs. The AC drain outlet, located beneath the front passenger chassis, also counts as a drainage point.
