I have a 2002 Chrysler Concorde Lxi 3.5L V6. When the car is running, I can hear a constant whistling noise. It sounds like its coming from under the steering wheel.
The whistle just loud enough to be irritating and high enough pitched that my father-in-law can't hear it, I can barely hear it, but my wife can hear it extremely well.
Occasionally, there is also a ticking noise I can hear too. The ticking doesn't hapen all the time or last very long (maybe about 5 mintues). When it does, it's about 2 ticks per second.
Outside the car, with the hood open, I can't hear the whistle or clicks over the engine noise.
The whistle noise does change in pitch occasionally, but I can't pin it down to changing during accelleration or braking. It's just random. It doesn't seem to matter if the car is warmed-up or cold.
The "check engine" light is not on.
If anybody has a suggestion as to what this could be, let me know.
Thanks, Paul
