Hello to group. The subject of my concern is a 1999 Aurora 120,000 miles. My major concern is a fire.
Details: I have developed an intermittent "crinkling" sound in dash behind drivers side dash. This is the best I can describe it. When engine is running all lights will flicker when it happens [ there is NO specific length of time between occurrences ] Here is the scary part... When car is NOT running with no key in ignition it STILL does it. I have never done anything behind the dash nor been in there. I do not want to drive for fear of a electrical fire. I am asking for ANY ideas from group.
You are having a multifunction switch issue. Just a guess, but yes the clicking you hear is from the LCM but I would almost bet the issue is originating from the switch. See these threads if you don't see anything wrong with the LCM. Fwiw, you can unplug the connector from the LCM and at least be able to park it without draining the battery. You would also be able to drive with it unplugged during the day, brake lights and signals would still be functional.
