I hung a hampton bay ceiling fan (Huntington III), controlled by a simple single light switch, and the fan works well, but the lights do not work at all. I wired white to white, black to black, green and blue to outlet box ground. I am guessing that it's a manufacturer's defect, since it is getting power to run the fan, but could I have screwed up?

Blue connects to black.

Blue ground to black does it. Thanks! (blush)

No problem.
