I have a 2002 Beetle with the 1.8 turbo motor in it. I am having trouble with the cooling fans and a/c compressor. I have changed the relays, checked the refrigerant, changed the high pressure switch, the FCM, battery fuse panel and all interior fuses. I have s working fan jumped across the sensor running anytime the key is on, but if I understand correctly, that fan is on a separate circuit altogether. the fcm has 12 volts going to it, so i'm thinking a ground problem of some sort. I cannot seem to find it though. Any suggestions would be appreciated.
