Door Light Switch Cleaning/Replacement
One of my door light switches is inoperative. If I unscrew the nut will it fall off into the void and never to be seen again? And, can I access the circuit from inside the car for testing?
Thanks in advance

that's not a nut, it's the switch body itself. they unscrew towards you. when you do unscrew it, don't pull hard, they're on a short lead.
once you have it out, you'll see the wire is crimped in a terminal on the end of the plastic plunger. the wire side of the switch body is slightly conical, so that the wire terminal centers itself when making contact.
take a very pointy craft knife and scrape the entire area where the end of the terminal makes contact with the end of the body. even though i bought two new switches, they've worked fine since scraping the corrosion from them. it's a pain if the wire is very short, mine barely pulled out of the door. they're not accessible from inside the door frame.
