2024 Mazda MX-5 Miata — windshield replacement created a highway whistle

GarageWrench215Community StarterDec 31, 20252024 Mazda MX-5 Miata ClubPortland
A windshield was replaced and now there is a whistle around highway speed that did not exist before. Glass looks seated. Any simple way to locate the air leak before taking it back? I am in Portland. I would rather test this logically than replace parts.

This is usually cheaper to test than to guess. Move a coil or plug on the 2024 Mazda MX-5 Miata if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. Do that first. I'm keeping receipts and dates in one folder.

Log the conditions before you spend. Two 2024 Mazda MX-5 Miatas can feel identical and have different causes, so measure before you copy someone else's repair. Don't erase codes until someone who can help has seen them. On “5 miata — windshield replacement created a,” that was the fork that mattered for me. When does it actually happen? Climate here is different, so treat that as a local data point. Trying not to diagnose from the couch.

Start with the test that can prove you wrong. If a shop can't duplicate it on the 2024 Mazda MX-5 Miata, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. If it doesn't change the out-the-door or the repair estimate, it's noise. I refuse to clear codes until someone else sees them.
