wiring exhaust fan in bathroom

I have a Nutone exhaust fan model QTN110E that i have installed in bathroom & went to wire up & have misplaced the diagram which tells me what the colored wires from fan go.I can run a copy of fan diagram from web site but it does not give color of wires & what wires operate what.I have pulled wire from panel box to exhaust fan & on to switch in bath room.wire coming from panel box has black,white,& ground.wires from exhaust fan
Blue & white together
Red & white together
Black & white together
One is supposed to operate a night light
One is supposed to operate 2 bulbs
One is to operate fan
Night light im not going to hook up. I have had it where light & fan would come on but would not cut off at switch & had it wired but breaker would trip.
Any help would be greatly appreciated.Also please break down so i can understand which wires go where since i am not an electrician.

Did you run 3-conductor cable to the switch?

With 12-2 to the switch box you will have to put the fan and light on the same switch.

To test which wire group on the fan goes to each function connect the neutrals to power in white. Then connect each fixture hot wire one at a time to the power in black to determine which function it is.

At the fixture:
Cap the hot wire to the night light.
Connect the whites of the fixture to the white of power in.
Connect the black power in to the white* of the cable to the switch.
Connect the hot of the light and fan to the black of the switch cable.

At the switch:
Connect black and white to the switch.

Grounds connected in the usual manner.

*The white wire of the switch cable muse be remarked black, red, or any color but gray, green, or white on both ends using felt tip marker, colored tape, or paint.

Ray gave you the wiring but maybe you didn't understand it.

Start with your line from the panel.
Connect the white wire of that cable to the fan's white wires. This is neutral.
Connect the black wire of that cable to the white wire going to the switch.
Connect the black wire from the switch to your fan and light hot wires (blue and black)

Sorry for the crude drawing....still perfecting my craft
In the drawing the blue wire is actually white.

PJ's is more representative of your situation but here's an old crude diagram for a light that I did a while back. Just imagine both the light and fan hot at the same connection. Maybe between the two you can see your mistake.

There is not enough space in the small junction box on the fan to allow switch loops to be used, especially if you want more than one function to work. Bring the power into the switch first. I then run a flexible conduit up to the fan housing from the switch.
