Please help! My wifes 2003 1.8 automatic Beetle/Dream Car has A/C problems. The condenser fan comes on, but the compressor clutch does not engage when the A/C is turned on. The strange thing is that the engine does some kind of spurratic, surge thing (like a pulse)every few seconds only when the A/C is turned on. The clutch makes no attempt to engage (even while the engine is surging) and makes no strange noises.
