The mystery continues with the switch. I have checked out all the lights and it has nothing to do with any lights.
As was mentioned above, it might have something to do with the Nav or Entertainment system. I have both of these systems and will need some coaching for these from my teenage grandson.The RED switch issue will now likely have to wait until he is finished school in about two weeks.
The owner of my local auto repair shop said it was very likely installed by either the CIA or NSA and will remain a secret until either I receive top security clearance or I find a young hacker to look into the government files.
At some point the mystery will be solved---but for now it is a good conversation item.
