A properly installed windshield should be quiet, dry and solid. If something doesn’t feel right after a replacement, whether we did it or another shop did, here are the most common problems, what causes them, and how Reyes Glass Group fixes them.
Water leaking from the windshield
Signs: damp headliner or A-pillar, water on the dash or floor after rain or a car wash, foggy glass.
Causes: a gap or thin spot in the urethane bead, a damaged or missing molding, or rust under the old seal.
Fix: we find the leak point, then reseal it or reset the glass. See windshield leak and reseal.
Wind noise after windshield replacement
Signs: whistling or rushing air at highway speeds, usually from the top corners.
Causes: a loose or missing molding, glass set slightly too low or off-center, or non-acoustic glass replacing an acoustic windshield.
Fix: new molding, a reseal, or the correct acoustic glass.
Windshield rattling noise
Causes: loose cowl panels, trim clips that weren’t replaced, or a mirror or sensor mount that isn’t fully seated.
Fix: we refit or replace the clips and trim.
Other windshield replacement defects
- Distortion or a wavy view: low-quality glass, or non-HUD glass on a heads-up display car. The fix is the correct glass.
- Warning lights or lane assist not working: the camera wasn’t recalibrated. See ADAS recalibration.
- Auto wipers not working: the rain sensor pad wasn’t replaced or seated.
- Rust spots along the edge later: bare metal wasn’t primed during the install.
- A new crack from the edge: stress from an uneven bead or a tight fit.
How to avoid problems
Most problems come from rushed installs: skipped primer, cheap urethane, reused clips or missing calibration. Follow the aftercare steps for the first 48 hours too.
FAQ
Another shop installed my windshield. Can you fix it?
Yes. We diagnose and fix leaks, noise and calibration problems on any install.
Is a small leak dangerous?
A leak often means the bond isn’t complete, which can affect safety in a crash. Have it checked soon.
