my a/c clutch engages only when it's "cold" and when i rev hard. meaning that at idle, it usually doesn't engage.
thinking it was a weak a/c magnetic clutch, replaced it but the problem persists. connecting a wire directly from the batt to the clutch to test it affirmed that it simply wouldn't engage at the batt's voltage (and the batt is new).
i can only conclude that the pulley mechanism is faulty. any other areas i could examine?
the a/c uses a piston type compressor, not sure if that's what the "york" compressor refers to though...
appreciate it if someone could tell me the part number of the pulley, and if it is available seperately without the clutch. thanks!
