How to Fix Car Window Leaks?
2 Answers
Apply silicone sealant to the joint seam. Relevant details are as follows: 1. Causes: The reason is that the rubber gasket has aged over time or was not cleaned properly during replacement, such as dirt or broken glass remaining at the joint, causing gaps. Naturally, rainwater can easily seep in during rain. If not addressed promptly, the metal sheet where the windshield is installed may rust and rot. Generally, avoid using hard-setting adhesives like cyanoacrylate (super glue), as they tend to crack after sun exposure. 2. Warranty: If the car is still under the three-guarantee coverage, you can report the issue to a 4S shop for repair. According to the "Automobile Three-Guarantee Regulations," if the windshield leaks within the warranty period, except for replacement and maintenance, the only option is repair.
I often fix my car myself and have encountered the issue of window leaks several times. It's usually caused by aging sealant or damaged door seals. First, locate the leak point by drying the window and then spraying it with a water hose to see where the water enters. If the seal is broken, buy a new one from an auto parts store and replace it—it usually costs just a few dozen yuan. Remember to clean the drainage holes at the bottom of the door by poking them with a wire; if they're clogged, water can't drain and leaks easily. Small gaps can be repaired with silicone sealant—just apply it and wait an hour for it to dry. It's best to do this on a sunny day for better results. Also, check if the window frame is loose and tighten the screws to prevent recurring issues. For prevention: clean the window and door seals every six months to avoid excessive dust buildup. Simple DIY saves time and money while teaching you a handy skill.
