At idle, I noticed a tick-tick-tick noise only when the ac is running. When the AC is off there is no noise. Just noticed it today! Cools fine. Belts and all pullies and tensioners fairly new. Did not see any wobbles on AC cluthc or tensioners. Cycles on/off fine. Any ideas? Archives were not conclusive.

I sure hope I am not developing a list of new problems.

TIA
