How to Drain Water Inside the Car Door?
3 Answers
Methods to drain water inside the car door: 1. There are three drainage valves at the bottom of the door. When the door is closed, the drainage valves will automatically squeeze out the water inside the door. 2. If the drainage valves are clogged, you can use a tool to widen the gaps of the valves to allow water to drain. 3. You can use a hair dryer to blow dry the wet areas, speeding up the evaporation of the water. 4. Visit a 4S shop directly for professional inspection and maintenance to prevent water from causing short circuits in the electrical system. Common causes of water entering the car door: 1. Rainwater flows into the door through the sealing strips outside the window. 2. During car washing, water enters the door through the sealing strips outside the window. Accumulated water inside the door can increase the vehicle's weight and, in severe cases, lead to corrosion, rust, damaged circuits, or malfunctioning window switches. It is important to remove the water promptly.
There's water trapped inside the door that won't drain out. I've dealt with this several times myself – it's quite simple. There are usually small holes at the bottom of the door called drainage holes, which can get clogged with mud or leaves and cause water accumulation. Just use a soft thin stick or an old toothbrush to poke the hole and let the water flow out. If you don't have tools, park the car on an uphill slope or leave the door open to let the water drain naturally. Afterward, check if the door seal is aged or cracked – if it is, replace it with a new one, which only costs about ten bucks. When washing your car, avoid using a high-pressure water jet directly on the door gaps, and regularly clean debris around the door edges to prevent recurrence. If water stays inside too long, it can cause the door panel to rust and affect the window mechanism, so don't delay – it only takes a few minutes to fix.
I find water accumulation in car doors quite annoying, but it's not difficult to deal with. There are drainage holes at the bottom of the door—just poke them open. If they're clogged, use small tweezers or a compressed air canister to blow them clear. After draining the water, use a towel to absorb any residual moisture and keep the interior dry. It's also a good idea to check the sealing strips afterward; replace them if they're worn out—buying parts online and installing them yourself is cheap. Prolonged water accumulation can corrode the door frame and damage the window regulator. When washing the car, remind them not to spray water forcefully into the gaps. Address any water issues immediately to avoid small problems turning into costly repairs.
