What Causes Water Leakage in the Malibu Trunk?
1 Answers
The reason is that when the air conditioning is turned on, objects in the rear will cool down. When the air conditioning is stopped and the windows are opened, hot air containing a large amount of moisture enters the car, causing condensation to form in the rear. Due to the car's sealing, this moisture is not easily evaporated and accumulates, leading to water pooling in the trunk. Therefore, it is not advisable to set the air conditioning temperature too low. Additionally, proper ventilation inside the car should be ensured. Below are solutions for fixing trunk water leakage: 1. Drain the water: There is a rubber drain plug at the bottom of the spare tire compartment in the trunk—removing it will allow water to drain. 2. Locate the leak: Check if the trunk lid is deformed or if the surrounding rubber seals have aged. After spraying water with a hose, observe which areas allow water to drip in or, after closing the trunk, check for light penetration to mark the spots. 3. Seal with adhesive: Purchase a bottle of silicone sealant, open the trunk, remove the interior panels, and apply the sealant to the marked areas—preferably on the outer side. The rear bumper must also be removed, as sealing is impossible without doing so.
