Hot Insulation Smell

[Lincolnlov]

Well boys (and girls) Took my 03 LS to the dealer for the second time for a hot insulation smell. First time tech went out with me and we couldn't smell it. This time I reported that I only smell it after several hours with the headlights on. After a bit of discussion the service manager told me that it was probably electrical grease in the switch which was heating up (supposedly normal). I was told that there probably couldnt be a fire from this since the switch only runs on 5 (five) volts. Anyone know if that is true? After asking if they could examine the switch for heat damage I was told that perhaps they could replace the switch. Had to wait a day for the switch but they changed it out and I am now with a different switch that I presume is new. It turns with less force that the original. I have not had the opportunity todrive a few hours with the lights on yet. Will report the results when I get in some road time.

Wow that sounds shady. Given the way they ended up handling it I would think it may.

Did you drive it around with the headlighs on in the daytime?

I distinctly remember suggesting that to you. If the smell came back in the daytime with the lights on, it would be a good indicator it's your headlight circuit.

Frogman,
Nah, no time to drive it day or night! Maybe in a week or so!
