Hello...
A new compressor was installed on my car recently ('94 LX, 4.6l).
I was wondering how the A/C compressor operates in this respect: I have noticed that it 'cycles' every few seconds. I have observed that the pulley on it spins for a couple seconds, then it stops for a few seconds. The A/C is blowing cold air, which indicates the system is working ok.
I would like to know if that 'cycling' is part of the normal operation of the condenser. It makes a sound I didn't observe, as part of its cycling between "stand-by" and "on." The sound is nothing more than a small "psst" - system pressure fluctuates between the high range of normal (when compressor is on) and just under normal (when compressor is 'off').
Thanks!
