Pat, even "saliva" will temporarily "cleanse the lense" of it's fogging problem on my car. You would think that would tell the Chrysler service managers that the problem is sometimes on the "outside" of the headlight (not that I want them "spitting" on my car to diagnose the problem).

I rue the day I have to take my car to the dealer. They'll probably want to do a front end alignment to correct a burned out tail light.
