Mine doesn't work. It doesn't appear to have a live feed as it won't turn on either manually or via the door switches. I'm sure it worked when I bought it, but that was a few years ago. As it's behind me, I don't really notice it ;-) Any ideas?
have you checked to see if there is a voltage at the terminals? remove the bulb and check put a dc voltmeter across the red and black( + & -), here we be the best place to start if the other interior light is ok.
