Your AC is probably low on refrigerant and the system is cycling rapidly. The clicking is the compressor engaging/disengaging as it hits the low limit.

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. _________________________________________________________________ Insert movie times and more without leaving Hotmail®. http://windowslive.com/Tutorial/Hotmail/QuickAdd?ocid=TXT_TAGLM_WL_HM_Tutorial_QuickAdd1_052009 [Non-text portions of this message have been removed] ------------------------------------ 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!
