FIXED! Car A/C Compressor Clutch Won't Engage

If your Air Conditioning compressor isn't working (the clutch won't engage) then watch this video. The A/C switch on the dash switches the compressor on, with one exception. If the PCM (powertrain control module) senses low pressure in the low pressure fluid line, it will stop the compressor clutch from engaging to prevent any damage. This is because low pressure = low fluid, and r 134a is also oil/lubricant for the compressor and if you don't have fluid then you will damage the compressor. HOWEVER, if you cannot turn the compressor on, you cannot recharge your AC levels (grrrr). So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself.
