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.

My A/C is new...installed 6 months ago. > > ------------------------------------ To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnewsYahoo!
