This subject appears to be a common issue, but i'm not getting anywhere with my efforts. I have a 2002 Beetle 1.8 turbo. Before blowing a coolant hose and warping the head, I was trying to track down why the coolant fans and ac compressor aren't coming on. I repaired the other issues and am now back to fans and a/c. I live on the Texas/Louisiana Border and cannot impress how important those items are. Up to this point, I have changed the high pressure a/c switch, the relays, the tempature sending units, the one on the tee coming off the radiator and the one in the hose by the block, the FCM, the battery box fuse block and traced wires till i'm blue in the face. I've got power to the FCM but no power to the fans or a/c compressor. I'm pretty fair at mechanicin', but this is getting the best of me. Any help would be appreciated.
