The door drain holes on the Corolla Hybrid are located at the bottom of the doors. The Toyota Corolla features a MacPherson strut front suspension and a torsion beam rear suspension. The entire lineup is equipped with a 1.0-liter three-cylinder turbocharged engine, delivering a maximum horsepower of 122 hp, peak power of 90 kW, and maximum torque of 173 N·m. The vehicle offers both 6-speed manual and CVT transmission options. Inside the Corolla, the center console boasts a 10-inch display screen with a two-tone color scheme (dark upper section and light lower section). Soft-touch materials are used throughout the cabin, while the steering wheel features a multifunctional design wrapped in leather.

I've been driving a Corolla Hybrid for several years, and the location of the door drain holes is quite simple to find—they're at the bottom edge of each door, with several small holes hidden beneath the rubber seals inside the door. Specifically, if you open the door, crouch down, and run your hand along the very bottom of the door, you can feel a small hole or slot where rainwater drains out to prevent water accumulation inside the door, which could corrode internal components. Once after a rainstorm, my window stopped working, and upon inspection, I found the drain hole clogged with mud. A gentle poke with a toothpick fixed it. The design is effective but inconspicuous, so regular checks are necessary, especially before the rainy season. If blocked, the issue isn't visible from the outside, but water trapped inside could damage the window regulator or cause rust, leading to major repairs. Since then, I clean them quarterly to keep them clear and avoid trouble. The drain holes are uniformly located in the same spot on every door—front and rear—making the Corolla Hybrid's drainage system quite reliable with basic maintenance.

As someone who frequently helps friends with car repairs, I'm familiar with the location of drain holes: On the Corolla Hybrid, each door's drain hole is located at the innermost bottom of the door panel, specifically beneath the door gap where those small round or oval holes are positioned. When rainwater seeps through the window gaps, it drains out through these holes to maintain dryness. The key to locating them is their proximity to the chassis - you can spot the holes by bending down outside the car, but you'll need to gently touch with your hand to confirm their position at the rubber edge. Importantly, regular cleaning prevents clogging - simply use compressed air to blow or a small stick to clear them, which is quick and effortless. Though small, these drain holes protect the entire door's electronic systems from corrosion that could affect window regulator sensors. A cleaning frequency of once every three months is recommended.

When I first drove the Corolla Hybrid, I encountered water accumulation in the doors. The drainage holes are located at the very bottom of each door, slightly inward along the edge. You can easily spot the small holes hidden along the inner edge of the door. Maintenance is simple—just use a thin wire to clear any blockages. The position is consistent, making them easy to find on both the front and rear doors.
