I meant that I measure 12 volts to ground from both sides of the fuse -- confirming that it is not blown or otherwise faulty.



My car is indeed a pre-facelift (production 11/2002). But because it was easy to check, I went and checked fuse F107 anyways and ... DING DING DING!


Fuse F107 has continuity to big red/blue wire at the fan connector -- the one that is supposed to have constant 12v.



I checked fuse F107 and it is bad. There was 12v on the bus side, and 0v on the downstream end. I removed the fuse and I haven't used this kind before; it is not immediately obvious whether it's blown or not. But the DMM says it has very high resistance. So newtis and my Bentley manual are wrong!



I am piecing the puzzle together here. I did find a part of that wire near the connector which had been shaved, probably from getting whacked by the engine bay fan. I realized during this troubleshooting process that that wire has 12 volts all the time, even when the key is out. It must have just brushed the chassis and shorted, and blown the fuse, and since we all thought the fuse was F61 like the manual says, we stopped there. But the wiring diagram was wrong the whole time! I wonder if the other poster (daveking) has the same problem.



My gut was telling me there was no way a #6 wire could have broken without shorting out somewhere, or having an intermittent connection.



Thank you all for your help! And especially wpoll, for finding the wrong wiring diagram that turned out to be right!
