In my post yesterday, I claimed all was working well. And it was ... until last evening. I drove eight miles with the headlights on and no prob. After picking up a friend, I restarted the car, turned on the headlight switch and -- bang. I get the warning light on the dash as soon I stepped on the brake to put the car in reverse. Argh. But then I tried something different -- I shut down the car, restarted and, without headlights, all was fine. Then I turned on the headlights slowly -- one click at a time -- and my problem didn't reappear.

I should explain: My headlight switch has been a bit jerky lately -- feels like the detents are worn, and sometimes I have to exert more-than-usual force when turning it to get the headlights on. Plus, the pull-out feature for the driving lights no longer works ... it slides out and the driving lights illuminate, but won't remain in position.

So yesterday I finally discovered when the headlight switch goes just a shade too far in its clockwise rotation, it does something to the circuitry to cause the tail lamp problem (and warning light). Who'da thunk it?

Naturally, I'm now ordering a new headlight switch ....
