I have two wires coming in. I've connected one black to black on fan,one black to blue on fan, both whites coming in to white on fan, green on fan to green on mounting bracket,
Both bare wires together. Fan works but light does not

You said you have 2 wires coming in but then you say you connected 1 black to fan and 1 black to blue and then whites. Do you have 2 blacks or 1. Is it a single wall switch? Or 2? If 1 wall switch, connect the blue wire to the black wire that you used for the fan. Light should work. Cap off the other black and put it in the box. With 2 wall switches, you usually find a black, red and white. Hope this helps.

Stop!

What you have is more than likely a switch loop that should feed the light circuit (blue).

What I would expect you to have is a Black/White/Bare copper that is the supply cable.

Does one of the white wires have either black or some other tape coloring on it?

If so, this is the feed conductor to the wall switch. You would connect the Supply black, to the fan black to the White wire that is taped.

Connect the other black wire to the fan blue wire (light). The White from the supply cable connects to the white from the fan.

The fan should now work off the pull switches and the light will work off the wall switch.

Please make certain that there are at least two cables in the ceiling. If you have a volt meter you can test this by placing the black probe on one of the ceiling whites and the red probe on the black. If the voltage is a constant 120 +/- than that is the supply line.

NEC Code allows the white conductor to be re-tasked so that it can supply power to a switch. It is not allowed to be the return from the switch.

Don, think I misread this, 2 wires coming in is really 4 wires. Then a switch loop makes sense, if they use the wall switch for the light so it meets code.

When you say the fan works, is it opperated by the switch?
