Sounds like the normal cycling of the ac compressor... maybe a bit fast.. could be just a hair low on r12...

When I turn on the A/C I have a constant clicking noise. 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. ------------------------------------ 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!
