I purchased a Hunter fan with kight assembly, Model # 53161, Item # 302359. I am having trouble making the right wiring connections. I have a green ground wire, awhite wire, a red wire and a black wire coming from the celing. I connected the green ground wires toghter, the white wies together. The back wires together, and the red and blue wiers together. The fan works but the lights will not work. What am I doing wrong?
