Car Forum / Chrysler Cars / September 2007Concorde whistling noise
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 > I have a 2002 Chrysler Concorde Lxi 3.5L V6.

If it does it with the engine idling and the car sitting still, disconnect the vacuum hose from the booster and close the end of the hose off (duct tape or a plug) - then go back to the driver's seat and see if the noise is gone. Repeat a few times to convince yourself that you can consistently turn the noise on and off like that. If so, replace the booster. Good rebuilts are at the auto parts chains for around $80 (same exact rebuilder as NAPA, but NAPA gets over $100 for the same part).

I'll give it a shot tonight. Thanks for your help. > > I have a 2002 Chrysler Concorde Lxi 3.5L V6. When the car is running, > > I can hear a constant whistling noise.

I'm a knucklehead, so you may find the solution amusing: As it turns out, when I took the front-end apart to do it's 100K mi replacing the timing belt, water pump, serpentine belts, etc... I did not put the hood release cable back in the car very well. It had come loose and was rubbing up against the serpentine belt. The belt had scraped off the plastic and was making a whistling noise as it rubbed up against the metal wire in the cable. I moved the cable back out of the way and secured it, so the noise went away! -Paul |
