wiring confusion - ceiling fan installation

I am in the process of installing two ceiling fans in my family room. They are both replacing existing light fixtures that are controlled from a single switch. Upon removing the existing fixtures, I've stumbled upon some confusing wiring. In one box I have two cables coming in... a gray cable containing a black, red, white and bare wire... and a white cable (with markings), containing a black, white and bare wire. The other box has these same two cables coming in along with an additional third white cable (no markings) also containing a black, white and bare wire. The ceiling fan has a black, white and blue wire along with a green ground wire. It comes with directions to wire to either the 3 or 4 wire comination, but assumes a single cable in the box. Any insights would be appreciated.

Thanks.

You are installing combo fan/lights right? Blue is the fan and black is the light I bet.

Tell us about the switches that control the light fixtures and what color wires are connected to the switches.

I'm an office bound electrician and had not touched a wirenut in years but installed one for a lady friend yesterday........... 'bout killed me ................ LOL..:D

Need more info; What wires are on the wall switch ? You didn't say what wires where on the existing lights. Where any of the other wires spliced together ? Also which ceilng box contains what(the one closest to the wall switch , for example)Lastly do you have a multimeter ? I assume you are installing fans without light kits, is this correct?

Isn't the black usually hot for the fan and blue for the light kit?:)

Answering some of the follow-up questions...

I am installing combination fan/light fixtures. The directions seem to indicate that the blue is for the fan and the black is for the light.

The switch on the wall is a single on/off switch. It has a white cable coming in, with black and white wires going to the switch and a bare ground wire.

The box with the three cables is closest to the wall switch.

I don't recall how the existing light on the 2 cable box was wired.

The 3 cable box had 1) the gray-cable/red-wire and the plain-white-cable/black wire connected to the light fixture/black-wires 2) the marked-white-cable/white-wire and the gray-cable/white-wire connected to the light fixture/white-wires 3) marked white-cable/black wire, gray-cable/black-wire and plain-white-cable/white-wire connected by a third wire nut and 4) all bare ground wires grounded.

O.K. we are making progress. First make sure your boxes are rated to support a ceiling fan. If not swap out the boxes for the heavier duty fan type after drawing out your existing wiring. Now with the power off (of course) connect the blue "light" wires coming out the top of the fan to the existing colored wires that were previously connected to the ceiling lights. These are called "switch legs". Next connect the white wires coming out of the fan to the white wires previously connected to the ceiling lights. These are called your "nuetrals". Next connect the black wires "motor" coming from the fans to the other wires in the ceiling boxes. These wires were NOT previuosly connected to the ceiling lights but are in the ceiling boxes spliced together with wirenuts. These are "hots" and have power on them no matter if the wall switch is on or off.Also these "hots" will have a white wire connected to a colored wire in the ceiling box closet to the wall switch, do not change this,(it is NOT a nuetral)it is the constant power down to the "supply" side of the wall switch. Last connect bare/green wires together which are your "grounds" When you are done you will be able to control both lights from the wall switch together and you will be able to control each fan indepently by using the pull chain on each motor wheter or not the lights are on or off.
