I bought a used ceiling fan from craigslist and just installed it. Its a hampton bay that takes intermediate size light bulbs. Only one of the four lights works. The weird thing is if I take the bulb and put it in the opposite side than that works but then put another bulb in its place, the extra bulb wont work. Adjacent sides don't work at all. Also when I turned the fan on, it was touching the little part that sticks out from the chain. The light fixture was a little crooked so i bent it back.
How can i fix it?
