I own a 1999 Honda Civic EX with 100,000 miles. For the past six months or so there has been a " squeaking" noise coming from somewhere under the hood. The noise is very intermittent, and it seems every time I try to look under the hood to see where it is coming from, it stops before I can get the hood open. As of late, the noise has been getting more frequent and I can hear it when traveling down the road (a few months ago it was only noticeable when idling). Also, the car makes the same noise when I turn off the car and slam the door.
