I have this wired whistle noise at the front vent at the right side. At first, I thought the problem came from the centre vent, and I took my car back to dealer. It took dealer one day to diagnose the problem and fix. Unfortunately, they couldnˇ¦t fix the problem.

I drove my car back and did the test again. I think the problem came form the lower vent at the passenger side. It occurs when the heat turn on, but when the regular or cold fan, there is no noise.

I am just wondering is there anyone has the same problem so i can share the experience? I drive TL 3.2 2002. Thanks.
