We had a run in with Murphy’s Law today. You know the headlamps that are on whenever you start the vehicle, even in daylight? In our Grand Cherokee we’ve had one out for a month or so, and finally got around to taking it in to be replaced.
We arrived at the appointed time, and were asked which light needed replacing. We explained it was not one of the at-night headlights but rather one of those which effectively are running lights. The service writer objected that he had no idea which to replace, all the lights were working.
So we apologized and left. Now we’re wondering why the light would be dead for some weeks and then decide to work, an intermittent short somehow “cured” by the rain we’re currently having? That really makes no sense, but we have no better theory.
