hi quick question if anyone has time. my ac will turn sometime while its not on like its slipping at first i thought the whole pulley was slipping but its not so anyway sometimes while sitting there idle it will make a constant noise when i let out the clutch. my question is why does it do this and in the repair manual it has ac cut out switch listed in trouble shooting under lacks power, accelerates poorly, or hesitates. which mine does all of. are the two related?
thanks
