I have a ceiling fan don't know the make or model and is compatible to light kits, I bought a new light kit(a harbor breeze light kit)but will not work after I wired it up, there's only to wires (a blue one for the black wire coming from the fan)and a white one (for the white wire coming from the fan)and I've hooked them up the right way but the fan works but not the light. What can be the problem?
