Where do you connect the blue wire

Lost instructions! if the fan has a white blue and black wire and a green ground. the ceiling only has white black and ground. which do you hook the blue (lite kit) to white or black?????

Next time don't lose the instructions.....

Black is your answer...

If just simply hooking the blue and black together with the black from the switch/power supply does not work you need to replace the wire going to the fan with a 12/3 wire(white,black,red,ground) along with a switch, what you have now is a 12/2(white,black,ground)

Here is the following way it should be hooked up using 12/3 romex to the fan from wall switch.
White,Black, ground power supply
Make sure 12/3 is fed to the fan location.
From the power you Y off the black to the red with a piece of red wire to the switch.
Then from the switch is red wire.
Then at the fan red connects to blue, black connects to black, white to white, and ground to ground.
