I'm sure you are right, David. That's what MB Doc told me but I misunderstood. Since then I've pulled that fuse and put it back. It went out for a while, but then came back on. I pulled it again and put it back and once again it's off, but for how long I couln't say. But the problem with the car is still with me. I hope you all will keep thinking about what I could try to do to fix it. Bob H
