One of my air vents makes a loud whistling noise when air or heat is on, it doesn’t do it on very low and sometimes not when it is on high. Is there a fix?
2 year old car with a 3 year warranty. Maybe you should ask your dealer?
If this is a new problem, there might be some debris in there. I managed to get a dollar bill stuck in mine.
