Seems to turn smoothe with some resistance . Ac is cold. cycles on and off. the belt tensioner for the compressor bounces more then when the ac is off. With the ac button off (led out) and the recirculation button on the ac still kicks on.
Can the compressor be replaced without flushing the system or is it contaminated ? Does GM use any inline filters to prevent contamination due to compressor failures?
Thank you very much.
