I have a 96 Honda Accord. Something strange has been happening to my car. Whenever I start it and turn on the A/C there is a very very loud grinding noise. Like when the car is started and you try to turn the igition. Whats also weird is sometimes when Im driving, the sound starts for like 2 seconds and goes a way. But if my A/C is on, its constant. It comes and goes, but I noticed its getting more frequent. Anyone any ideas?
