More information would be needed to diagnose your problem more accurately, but here are some tips to start:
1) Fans will not work with dimmers. If you have a dimmer controlling your fan, it will only work when the dimmer in is the full intensity position (if at all). You will need to replace the dimmer with a fan speed control. If one switch controls both the fan and the light, this will not solve your problem, as a light will not work with a fan speed control switch. You will have to settle with a standard single pole switch, a remote switch, or get one more wire between the switch and the fan.
2) If you have a fan speed control switch, but the fan doesn't seem to respond as it should, you may want to pull on the pullchain directly on the fan. If the pullchain is not set to high, your speed control will not work correctly.
3) If #2 or #3 don't apply to you, and you are simply using the pull chain on the fan, you may have a bad switch inside the fan housing, loose or disconnected wires to the fan (unlikely), or simply a bad fan motor.

do you mean the speed of the fan? if so, it'a relay generaly near the motor of the fan. If it's the heat who only came at high speed, you need to add some antifreeze.

It sounds like your blower fan resistor is not working correctly. Eventually it will stop working all together. I suggest that you get a replacement.

There is a fan motor resistor board located under the dash on top of the plastic duct housing on the passenger side of the vehicle. It is behind the glove box. Removing the glove box will help you to get to the resistor. The power to the fan motor uses various resistances on that board to get your lower fan speeds, but on the highest setting it bypasses the resistors since they are not needed. You always will get your blower motor to work but only on high only when the resistor board is bad.
