I have a 2006 Acura Tsx with 80,000 miles, I've done all maintenance required, but recently when i stop at a red light or stop sign, or just stop and chill in my car for a few minutes, after driving for a bit, with the A/C on my car whistles when the radiator fan turns on and you can only hear this if your inside the car. I've taken it to the dealer and 3 other honda/acura trained mechanics, but my car doesn't do the sound there, and they think I'm crazy. Somebody please shed some light on this

 

Whistle or whoop? There is an existing thread on the whoop sound.

 

yes sorry its a whoop sound, I checked out those threads gonna try some of those options hopefully they help thanks Luvmytsx for your help

 

No problem, glad to help.
