Is the fan and light in one unit? As in a ceiling fan? You must change the configuration inside the fan's electrical system.
If you wish to change a circuit in a switch at the plate, you must (1) Turn power off of the circuit, (2) open the switch junction and (3) rewire the switch exactly the same as the old one.
To split the two functions, you need to identify the two appliance circuits and add another switch in tandem with the old one. This involves a larger switch box and plate. This is best left to a professional, but if you feel you absolutely must do this yourself, there are instructions available on YouTube in video.

sorry but the light isn't serviceable
apparently the switch that controls when the fan kicks on and off is bad.
The fan does not have a switch - the thermostat switch runs the fan.
It sounds like your fan also has a light with it. If your wall switch is a two gang box with two switches in it most likely one switch is for the light on only and the other switch is for the fan on only. This can be checked out by installing the fan and making the connection green to green, white to white, black to black. Turn on one of the switches and see if the fan operates. Disconnect this connection and then connect the red wire to the black fan wire. Turn the other switch on. If the fan turns on again, then the two switches were installed to operate the fan and light separately. If this is the case disconnect the red and fan black wires and reconnect the black to black. This is the fan connection. Connect the red to blue fan wire and this is the light on the fan connection.
One can easily be installed. Locate the wire that runs to the water temp sensor. Splice this wire to a switch and then off to a ground. When you flip the switch it will ground the wire and make the fan come on. Do not get confused with the oil temp sensor. It controls the HOT oil light, not the fan.
how do you change a fan switch on a 1997 Chevy cavalira
Not usually, The light would have had to been wired with a three wire from the switch to the fan. One circuit to control the fan and the other switch to control the light. If this is your situation then all you will have to do is change the light switch to a timer and that will do what you want.
See: "How can you re-wire a wall switch that controls an outlet to control a ceiling fan?" (Follow the link below.) The procedure is the same whether the new device is a light fixture or a ceiling fan.
Some brand fans have a remote control kit that installs in the fan housing. Also if you have access you can run a separate switched voltage to the fan. In this case you would have to put a second switch in the same box that controls fan, unless it is a switch with speed control that came with fan. In this case you would have to install a new box (Old Work Switch Box from Home Depot or Lowes for example) and run voltage to the box, install a switch and run wire to fan and connect to light. One other possibility is to check the ceiling box and see if there is a spare red wire. If so you could use this to switch power to the light separately from the fan. Again it depends on the switch configuration and supply voltage feed.

Yes. Simply turn on the ceiling fan while the light switch is in the "on" position. Adjust the spinning to the level of your choice. Now the fan will turn on and off when you switch the light on and off.
