Help wiring (2) 3 way switches to one ceiling fan with light

I need help wiring a ceiling fan with light fixture. Here is the info:
-Power into wall switch box (just one) is B, W, Ground
-I took out the single pole switch and want to use two 3 ways to operate the fan and light separately.
-The fan has a B, W, Blue (light), Ground
I don't know how the two switches should connect to each other and run to the ceiling unit. Help!

Dave

That is not a three way. It is a duplex switch. You would need to run a three conductor (+ground) cable between the switch and ceiling box. Connections would depend on if power comes in at the ceiling box or switch box. If you have only a black and white connected to the switch and no other wires in the switch box power probably comes in at the Light.

Ray, thank you for the quick reply.
The power comes into the switch box from below with a black, white, and ground
I installed the three wire plus ground going from the switch box up to the fan

I have (2) seperate single toggle switches each with (1) black screw, (2) brass screws, and one ground screw.

So you do have two sets of three way switches in two different locations for a total of four switches? You didn't make that clear before so I am deleting my answer above as it is not relevant. In addition to the 3-conductor cable to the fan/light do you have two three conductor cables between switch A and B and switches C and D?

Let me back up and reorganize my notes since I'm very confused.
Forget all the info I've provided so far
I went to the hardware store and picked up two single pole switches
I have one location on the wall with one dual box in the wall
In that box I have the (2) single pole switches in it
Each switch has one toggle
I have the power coming up into the box from below with a black, white and ground
I have four wires (black, white, "marked black", and ground) going from the wall box up to the ceiling fan/light
I wired it according to what they said but there is no power to the fan/light
Also, I've discovered that a wall outlet next to the wall switch is affected by that switch
The ceiling fan/light has a black, white, blue, and ground coming out of its houseing

No more confused then I am.

You earlier described them in post #4 as I have (2) seperate single toggle switches each with (1) black screw, (2) brass screws..... That is a 3-way switch. (Note 3-way switches are single pole switches [Single Pole Double Throw.]) It sounds like you have the wrong switches. You need a regular light switch with two brass screws and a ground (Single Pole Single Throw).

I have four wires (black, white, "marked black", and ground) going from the wall box up to the ceiling fan/light
That doesn't make sense. You do have cable not conduit don't you? What was the original color of the wire marked black? (Note: usually only whites are re-colored.)

Also, I've discovered that a wall outlet next to the wall switch is affected by that switch
Open that receptacle and tell us the wiring inside? Also check if the tab between the screws on the brass side has been removed.

If you can provide pictures that might also help. http://www.doityourself.com/forum/li...-pictures.html

Typically one switch is connected to the 'marked 'black' wire and controls the light while the other switch is connected to the black wire and controls the fan. In your case, you'll need to pigtail the hot black coming into the box to attach it to both switches.

Then, in the ceiling it's black to black, marked black to blue, white to white and ground to ground.

This is all generic, your setup apparently has some complications.

Mitich's advice is generally correct but your situation is different. I think one of the switches was a switch loop for the receptacle so will you need three switches in the box, one duplex, one simplex or you will need to make both sides of the receptacle always hot.

The wall switch had only one single pole single throw in it before
I've changed the wall box so it can hold (2) single pole single throw switches in it for independent control options
I still have the 14/2 feed coming in from the bottom
I have (2) 14/2 lines going up to the fixture
The "marked black" is from the the 2nd line going up
I didn't hook up the ground or white from that second

Now the receptacle next to the wall switch has the following:
(3) 14/2 lines coming into it (two on the right side and one on left)
The (2) whites from the (2) lines on the right hook into the receptacle's left side screws
The (2) blacks from the (2) lines pigtail with the white from the single leftside line and run to one of the right side receptacle screws
The remaining black from the single left side line goes to the remaining right side screw on the receptacle.
What am I dealing with here?

That sounds like a switch loop. (Terminology note: There are no left or right sides to receptacles, just brass and silver sides.) Is the tab between the screws on the brass side broken? The cable whose white is connected to a black seems to be a switch loop cable. Do you have a switch some where for the receptacle?

The wall switch had only one single pole single throw in it before
I've changed the wall box so it can hold (2) single pole single throw switches
Did that switch control a ceiling light that you replaced with the fan?

The tab on the brass side is broken
The switch that controlled this receptacle is the one I'm using now to control the fan fixture

Then you'll need to nut together the two wires which were attached to that switch to make both sides of that receptacle always hot.

Good, now we have the correct information. While Mitch's answer again is good I'd do it a bit differently. Just replace the receptacle with a new receptacle.

The cable in the switch box you called hot was not a hot cable. It was a switch loop. To make it hot go into the receptacle box. In there connect all whites together (including the white previously connected to a black) to a pigtail. Connect all blacks together and to a pigtail. Black pigtail to brass and white pigtail to silver of the new receptacle tab not removed. You now have a hot cable to the switch.

Now to the switch box.
I have (2) 14/2 lines going up to the fixture
The "marked black" is from the the 2nd line going up
None of the wires on these two cables should be recolored.
Two pigtails are attached to the hot in. One pigtail to each switch.
The blacks of the two cables out go one to each switch.
All three whites are wire nutted together.

At the ceiling:

All whites including fan white wire nutted together.
One black to black and one black to red.

All grounds connected together and pigtailed to the switches and the fan/light. If metal box also pigtailed to the box.
