My 1998 Ford Escort runs great except for an intermittant squeal or screech that no mechanic has been able to fix. I've had it to one regular mechanic who thought it was the transmission, a transmission guy who said it wasn't but didn't know what it was and to two Ford Dealers - one who blew me off saying it didn't make the noise long enough to pin point so unless I wanted to pay a technician by the hour he couldn't help me,and the 2nd one told me he was certain it was the IAC Valve. He replaced that and said the noise immediately stopped. Unfortunately the noise continues. The squeal doesn't start until the car is warmed up about 5 minutes or so and it continues to make this horrid screech whether I'm sitting in idle or driving - with or without the air conditioner on. The pitch of the squeal also changes along with the engine RPM. It will also make the noise about a second or so after you turn the engine off and what's weird is I can look at the pulleys after a friend cuts the car off and it will make the noise about a second AFTER the pulleys and serpentine belt have completely stopped turning. After seeing this I thought it may be the electric fan because it was the only thing that was still turning after the engine completely stopped turning but I disconnected it and the car still makes the screech. So whatever it is, is still turning some AFTER the motor/belt/pulleys have stopped. What could be still turning after the motor has stopped besides the fan?? Can anyone help diagnose???? Help! Thanks
