Is It Normal for Water to Leak Under the Passenger Seat of the Buick Excelle?
2 Answers
Water leaking under the passenger seat of the Buick Excelle is not normal; however, if it's dripping due to air conditioning usage, that is a normal phenomenon. Relevant explanations are as follows: 1. If water is leaking under the passenger seat of the Buick Excelle, you should promptly visit a 4S shop or a professional auto repair shop to have the staff inspect it. 2. Identifying the problem is essential for targeted repairs. 3. Dripping from the air conditioning is normal. The evaporator box of the car's air conditioning system absorbs moisture from the air, which then condenses on the pipe walls and casing. If this moisture cannot be drained, it can cause dampness around the air conditioning system (inside the dashboard) and corrosion of components. The drainage outlet is typically located under the passenger seat. Therefore, if this is the case, the owner need not worry.
Having driven my Buick Excelle for five years, I can definitely say that water leakage in the passenger seat is abnormal—I’ve experienced it firsthand. During a heavy rainstorm recently, I noticed the passenger-side carpet was completely soaked. When I lifted it, there was standing water about half a finger deep, so I rushed to the repair shop. The mechanic diagnosed it as a loose sunroof drain pipe joint and cracked, aged tubing, allowing water to flow directly from the A-pillar under the floor mat. Another common cause is a clogged AC drain pipe—condensate can’t drain and backs up into the cabin. Other culprits include deformed door seals or cracked windshield adhesive. Ignoring it can lead to mild issues like mold and odors, or worse, electrical shorts and blown fuses, making repairs even costlier. I ended up spending over 300 yuan to replace the tubing. My advice: if you notice leaks, avoid washing the car and get a professional inspection ASAP.
