hmm well i have this problem but i cant figure it out... every now and then while my car is running the high chirping noise will start up.. like squeaking.. like as if its a belt or something but its not a belt.. its coming form the bottom center area of the engine.. sometimes when i turn on my a/c it will start making that chirping noise.. but i can thear it coming from the fans?? i dont know whats making that noise.. nor where at.. i just know the general direction of where the sound is :T.. does anyone have an idea of what it could be.. or have a clue on wha tim talking about hehe.. just imagine an old squeaky bed lol.. and start hopping on it
