It is coming from directly behind the drivers seat almost as if it's directly behind my left ear. It almost sounds like a relay clicking. It clicks at 4 second intervals. It occurs whenever the A/C knob is turned on. The fan speed doesn't affect it. Any ideas? My A/C is new...installed 6 months ago. > It usually signifies that there is not enough pressure in the A/C system, forcing the pump to be more active. If you are sure there are no leaks and the pressure switches are okay, have the A/C shop check your system and if necessary add refrigerant.
