Nice job, i've recently been troubleshooting my mk4 tdi bew for no A/C working. Replaced Fan control module, Fuses, Filled the system, Check power and ground to 2 pin connector on compressor. Not getting power. Relay was missing under the dash, after i replaced that i got power at the compressor. Now the compressor wont turn over so i supply 12v to the compressor and nothing. I have a new clutch kit coming to replace so i hope that fixes it!
