On most ceiling fan installations a three wire feed is used. A "hot" wire and the neutral feeder are brought to a two gang switch box from the distribution panel. One switch will control the fan and the other switch will control the light if there is one. On this type of installation the "hot" wire is connected to the top of both switches. The incoming neutral and the white from the three wire cable connect together in the switch box. From the bottom of the switch that controls the fan connect the black wire. From the bottom of the switch that controls the light connect the red wire. From the switch box the three wire feeder connects to the fixture box. In the fixture box the black wire of the three wire connects to the fan's black wire. The red wire of the three wire connects to the fan's blue wire to control the light. The neutral connects to the fan's white wire. The green wire from the fan connects to the bare ground wire of the three wire cable.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances
always use a test meter to ensure the circuit is, in fact, de-energized.

I am presuming that the home run cable goes to the breaker panel and there is nothing else on the circuit. In the wall switch box you should have a white and black pair from your source of power (120 volts). The other pair of black and white wires from the wall box should be going to the ceiling fan junction box. With the power off, connect the two white wires together with a wire nut. Connect the two bare copper ground wires together making sure that at least one of the ground wires goes under the green screw in the switch junction box. Turn the switch to the off position, no little indicator bump showing on the switch toggle lever. Now take the black incoming hot wire and put it under the top screw on the switch. Hot wires always go to the top of switches. Now put the black wire that is going to the light fixture under the bottom screw. Tighten both. Install the switch into the wall box with the switch handle in the down position. All switches when installed must be off in the down position. Install the switch plate cover.
To control a ceiling-mounted fan from seven locations, you would need a minimum of three four-way switches. Each four-way switch allows you to control the fan from three different locations by working in conjunction with two three-way switches.
you fix the light on the ceiling fan by puting a new light bulb in your fan
The red wire in this case would typically be connected to the black wire from the fan. This is because the red wire is used as the hot wire for the switch and needs to be connected to the black wire of the fan for proper operation.
Typically, in the US, the blue wire of a ceiling fan is for the light kit, the red wire is for the fan motor's high speed, the green wire is for the ground, and the white wire is for the neutral connection. You would connect the blue wire to the black wire of the ceiling, the red wire to the red wire of the ceiling (if there is one), the green wire to the bare copper wire (ground), and the white wire to the white wire.
A ceiling fan should typically be hung 7 to 9 feet above the floor for optimal air circulation and safety. With an 11-foot high ceiling, you can consider hanging the fan around 2 to 4 feet down from the ceiling using a downrod.

You may not have a ground wire in your older housewiring. Hook it somewhere to the metal plate that holds the fan to the box.

there are several reasons for fan failure . temperature rise is not enough to turn on the switches . or one of three switches isn't working two are near the thermostat and oneis on the block or the fan relay check haynes manual pg 121.
some vehicles have 2 fans, one for when the air is kicked on and the other fan for normal driving so there is 2 switches.
This sounds like a ceiling fan that also has a light attached to it. The black and white wires are used for the incoming supply voltage. The green is the ground wire. The blue wire is most likely the wire that goes to the lamp portion of the ceiling fan. The black and blue wires are separated from each other in the fixture so that the fan motor and the light can be independently switched. In these types of installations a three wire cable is strung from the fan switch box to the fixture box.For independent switching, the junction box should be a two gang box. From the power source in the switch box, the white wires all connect together. The incoming black connects to the top of the two switches in the two gang box. Bottom of the first switch to the black in the three wire cable, Bottom of the second switch to the red wire of the three wire cable.At the fixture junction box, incoming white wire to the fan white wire. Incoming black wire to the fan black wire and incoming red wire to the fan blue wire. If wired this way the light and fan motor can be individually switched on and off.If there is only one switch box, at the fan junction point connect the black and blue wires together to the incoming black wire. White to white wires together and green wire to the ceiling junction boxes ground terminal. In this configuration the switch will turn on both the fan and light at the same time.
On these types of installations an electrician would use a three wire cable set from the switch box to the fixture's junction box. At the fixture's junction box both the fan neutral and the light neutral would be wire nutted together with the incoming neutral from the switch boxes. From the three wire, the white wire would go to the fan and light's neutral wires. The Black would come from the bottom of one of the switches and go to the fan's motor lead. The red wire would come from the bottom of the other switch and go to the light fixture's lead. It can be done with two runs of two wire to the fixture. You will need a two gang switch box for this project to hold the two separate switches. You could use a single gang light switch box if you can still find where duplex switches being sold. A duplex switch is one that has the configuration of a duplex receptacle with the switches being one on top of the other. The cover plate is the same one used for duplex receptacles. To answer this question fully more information is needed. See discuss in the left margin.
Installing a ceiling fan is an easy way to save money on your energy costs. A ceiling fan uses much less energy than an air conditioner, and the breeze it creates helps you feel cooler even with your thermostat set higher. If you already have an overhead light fixture, installing a ceiling fan with a light kit in its place is not difficult. It's important to choose the right ceiling fan for your room, though, to maximize your energy savings. There are two aspects to consider--the wall to wall size of your room and the floor to ceiling height of your room. Most ceiling fans come in one of three standard sizes. The size is determined by the length of the fan blades. A 36 ceiling fan is good for a room that's 12 feet from wall to wall or less. Choose a 42 ceiling fan for rooms that are between 12 and 15 feet across. Use a 52 fan for rooms between 15 and 18 feet across. If your room is larger than 18 feet across, you should install two ceiling fans on opposite sides of the room to maximize air flow. These measurements are important, because too small of a ceiling fan won't create enough air flow to allow you to comfortably set your thermostat higher. Too large of a fan can be overpowering. The second consideration is your floor to ceiling height, which will let you know whether to buy a ceiling fan that mounts flush to the ceiling or one that comes with a down rod to let it hang lower than the ceiling. You'll want to choose a fan that will hang between seven and nine feet from the floor. Most down rods are somewhat adjustable, but make sure the one you choose will let your fan hang within that range. Keep in mind that if your fan has a light kit, the lights will hang lower than the fan blades. You may want to have the fan hang closer to the nine foot mark so the light is still above the seven foot mark. Another consideration in choosing a ceiling fan is blade type. A greater number of narrow blades creates more of a breeze, while fewer paddle blades create air flow without feeling as much of a breeze.
White is for neutral on the fan, black is power for the motor, and red is power for the light. If the power from the switch only has two wires (black and white), you would hook up white to white and hook black and red from the fan to the black wire from the wall switch. This means that you'll be powering the fan and light on the same switch and to change the fan and light separately you will have to pull on the chains or use a remote control.
