Hey guys, bought a used 2015 Accord a week ago, and have noticed there is this noise coming from front tweeters located near the side mirrors. My guess is it's got something to do with active noise cancellation. The sound is like water dripping or similar, and is always noticeable on the opposite side tweeter. When I sit on passenger side, the noise starts coming from left side, so weird. It picks up when its loud outside, and slowly goes away if I park the car in a quiet place. Has anyone noticed this, or does anyone have any fix for this problem?

 

Been thinking about this. First time I have heard this issue. Odd indeed. I suspect you are correct that it may be the ANC and I would start by either unplugging the ANC module entirely or disconnecting the microphones (located in the overhead console - remove four phillips screws: two in the sunglasses holder area and one behind each courtesy light lens).
