This is a continuation of my older thread which is now read-only. See
for the history.

I have followed the advice of Art and others. I found that the connector behind the headlamp was somehow melted and this seemed to have caused a connection problem. I cut out the connector and replaced it with some fully insulated, crimp-on spade connectors. This immediately restored my headlight function.

But a mystery still remains for me. Seems like since I did this, the bulb failure warning light comes on when the headlights are turned on. However, I not that: (a) This only happens when the engine is running and (b) When the high beams are turned on, the bulb warning light goes out.

I have checked all the other bulbs on the car and they seem to be working just fine. I suppose I can learn to live ignoring this but I would rather see if I can resolve this issue. So thanks for any suggestions.
