View Full Version : Voltage

Had voltage regulator replaced. The shop took out air boxes, belt tensioner, belt and finally radiator to replace it. They put in the new VR and put the car back together. Still has low voltage 12V to about 12.8V and now the A/C only works with the fan on high! If you adjust it any lower it does not work!
I am taking the car back for them to fix it, but what did they do wrong? Could there be a bad diode on alternator or loose belt for the low voltage? Something disconnected? Whats up with the A/C?

Well, no one replied here. I thought the group might like to see the progress on the car from the help I got on the 5 series forum:
