Fan speeds are usually controlled by a series of resistors on a circuit board.
When some speeds don't work, it means that you have to replace that
little circuit board.

Most are up underneath the dashboard. Turn on the heater blower motor and listen where the sound is coming from. The heater core is behind that sound.
Yes, there is a fuse for the blower motor.
Depends on what you mean by heater will not work. If the blower motor will not work, it can be a blown fuse, bad blower motor, bad blower motor switch, or a defective blower motor resistor pack. If you mean that the blower motor works but there is no heat, then it can be a clogged heater core, thermostat stuck open, or defective heater control valve.
Remove the wiring harness from the back of your 2005 Chevy Cavalier heater blower motor. Remove the heater blower motor retaining bolts. Remove the heater blower fan.
The a/c heater blower motor resister is located in the vehicle on the passengers side inside the housing next to the blower motor...............Remove the blower motor resistor wire harness connector.Remove the blower motor resistor screws.Remove the blower motor resistor.
On my 2002 Sunfire it's under the dash on the passenger side.
heat not working
1) Check the blower motor, make sure it is not making any weird noises.2) Check the blower motor resistor, its located next to the motor. It is what controls the lower speeds of the motor. You can try to find one at the junkyard.
the heater resistor needs to be replaced it is mounted in the heater box next to the blower motor

Are you asking about the heater blower motor or the engine cooling blower motor?
the switch, or the blower motor resistor, or blower motor usually it the last two at one time
