What are the aftereffects of replacing the front windshield?
2 Answers
The aftereffects of replacing the front windshield are: 1. The adhesive may not bond tightly with the glass; 2. Wind may enter through gaps between the windshield and car body, increasing interior noise; 3. When driving on bumpy roads, you may hear rattling/impact sounds from the front. The windshield replacement procedure is: 1. Remove black protective trim around windshield with screwdriver; 2. Use steel wire to separate sealant around entire windshield; 3. Scrape off residual black sealant with blade; 4. Apply polyurethane sealant to windshield frame; 5. Install new windshield.
After replacing the windshield, the most troublesome post-installation issues are leaks or wind noise caused by improper sealing. I recently helped repair a car where the owner discovered water seeping around the windshield during heavy rain, soaking and molding the floor mats. This happens when the adhesive isn't applied evenly or the sealing strip ages, allowing moisture to seep in over time, which can also lead to fogging or short circuits in electronic components. Another common problem is increased wind noise, especially at high speeds. If the glass isn't aligned correctly, the whooshing sound of airflow can be incredibly annoying. Additionally, built-in sensors like automatic wipers or ADAS systems for driving assistance need recalibration. If the repair shop skips this step, you might face delayed wiper response in rain or malfunctioning lane-change warnings, increasing accident risks. It's highly recommended to choose a certified installation center and conduct multiple tests afterward—otherwise, minor issues can quickly turn into costly repairs.
