coolnesss Posted November 10, 2014 Report Share Posted November 10, 2014 My 2002 ETC's A/C clutch cycles on and off at idle, sometimes every several seconds. It works fine, blows cold. No codes. What's up?? Link to comment Share on other sites More sharing options...
airmike Posted November 10, 2014 Report Share Posted November 10, 2014 I would guess you are low on freon. Someone else will chime in here with better info Link to comment Share on other sites More sharing options...

Cadillac Jim Posted November 10, 2014 Report Share Posted November 10, 2014 Cycling is normal, but as KHE says, cycling rapidly happens when the Freon gets low. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
