im getting a ticking sound when my a/c compressor kicks in. as soon as a/c is turned off the ticking stops. driving me crazy... any ideas? no noticeable vibration occurs when the compressor kicks in. i have looked and can not seem to locate the problem. | | |

Depending on model and insulation etc some appear louder than others. Mine on my 2000 silverado is getting louder as it gets older!!! | | |

I got a warrantied compressor from a GM tech to replace my locked up compressor, that's all that's wrong with them is that they "tick". Other than that, it works great,

After changing out the condenser and dryer did you add any oil to the system this system should hold about 8Oz of oil a good cummpressor should make a whiring sound not a clicking sound usually after a while the click will turn to a knock and then you end up with black death. What color was the inside of your old parts clean or a black dirty color | | |

I fixed this at an a/c parts supply in the parking lot. had the old guy help me fill the system afterwards with his manifold. asked him if anything additional was needed... he said system should still have enough oil in it. | | |
