Reasons for Water Accumulation in the Main Driver's Compartment

[DiGeorge]

Here are the reasons for water accumulation in the main driver's compartment: 1. Not closing the window during rainy days: After getting out of the car, failing to confirm whether the main driver's side window is tightly closed can allow rainwater to enter the main driver's compartment. Over time, this can lead to water accumulation under the main driver's compartment. 2. Issues with drainage outlets: If water continues to drip under the driver's compartment after ruling out human factors, it is necessary to inspect the car's drainage outlets. There are four drainage outlets in total—the front two are for sunroof drainage, while the rear two are for draining water flowing on the car.

Buddy, I've seen a lot of water accumulation issues in the driver's area at the repair shop, and they're usually caused by small things piling up. The most common culprit is aging or damaged door seals. Over time, the rubber seals deform and let water in, especially during rainy seasons or after car washes. Another issue is clogged drainage holes, like those at the bottom of doors or the slots under the windshield. If they're blocked by leaves or mud, water can backflow into the cabin. Sunroofs are also a major headache—I've seen many cars where clogged drainage tubes caused water to seep under the carpet. Additionally, if the A/C evaporator's drainage system gets blocked, condensation can overflow and accumulate. If left untreated, the water can corrode metal parts, damage wiring, and even affect the airbag system. My advice? Regularly check these spots, clear out debris, and replace worn-out parts to avoid costly repairs down the line.
